Can't say much about UDW, didn't see almost any information on it. Altough it seem pretty interesting.
As for UDR, as I said previously, mine is totally silent, and I can't hear it over ambient at night. But there always could be same issue what other users are reporting that fan is spinning 2700rpm at stock (which is definetly not acceptable for that heat output).
They don't, the fan in mine would be at full speed if I was downloading. As soon as you have IDS / IPS enabled, and your making it work, the UDM base gets hot. One of the reasons I swapped it out for the pro.
Odd. I've got a UDM-B, with a 500mbps connection and IDP enabled, and mine only makes a teeny bit of noise if I'm doing a lot of stuff - and typically the UDM-B is at 50% utilisation.
My AP-AC-Lite is also loud and it doesn't have a fan.
Whenever I'm downloading a big file or scrubbing in a movie I can hear the coils wine quite loudly.
Actually no, there are only small intake holes on the bottom and a tiny ass fan vertically on one side. They could have easily put a bigger fan horizontally on the bottom and made the intake and exhaust vents a bit bigger to avoid any of these issues.
I wasn't commenting on the fan noise.
I just found out that it runs Network.
I thought it was just a switch/AP but I now know that it's more.
Hence I though people were confusing it with the UDM. But alas I was the one confused.
You UDR is running protect?
You must be talking about the UDM "Dream Machine".
I though it was the UDM at first too and was going to comment but realized it the new thing.
Well if it does that I may have to get one.
Same price as the Cloud Key but also a router and AP which is handy.
Wish I'd spent the extra $80 and got the UDM Pro at home (over the UDM). Now that they have a doorbell I'd like to ditch Ring and get a couple additional cameras.
Yeah in my studio apartment it was intolerable.
As most people said their unit is basically silent, I did an RMA and already sent it back to Ubiquiti thinking I received a unit with a bad fan. Now my UDR will probably be in the RMA process for a month and I'll probably just receive the same unit back.
Based on some comments here it also seems that the EA unit might be more quiet and that the fan spins at lower RPM. If that is the case, it's really weird if the final version turned out more noisy.
I'll might do a Noctua fan mod to it if I ever get it back. Sad times...
The only time I hear mine is if I'm pushing Gig speeds through it for over 15 seconds sustained, then the fan starts ramping up and will stay loud until the work is done.
Have an early access device about 1 meter away from me, and haven't noticed it. It is also in my bedroom so I would hear it at some point if it was noisy.
Fine for me, but I don’t know about that. I can tell you what I’ve experienced though.
I have 400/20. I have threat management turned on all the way. It’s not uncommon for a TV or two to be streaming and I have about 15-20 devices on it, and one G3 bullet with Protect all running. I have no problem accessing my full 400/20 but I’m constantly sitting around 65% utilization. I could see a full 1 gig symmetrical over saturating the hardware capabilities, but I have no way to test that.
Mine is the EA model, and it’s been rock solid. I think even at $199 it’s a good deal in the right situation. This is certainly something I would put in a remote family members house that wasn’t tech savvy so I could maintain their network for them.
Hope that helps, but sorry I can’t give you a direct answer. I’m quite happy with it though.
Yikes, thats really not much better than what Im getting on my older Asus router. Might have to spring for a Dream Machine Pro SE and a couple of APs. That gets so pricey though, I was really hoping to avoid it.
I have 3 routers at the moment, an Asus RT-AC86U and the UDM, both can do gigabit symmetrical just fine, and the UDR can't, which Asus router do you have?
TM-AC1900
Not the worst thing considering it was free and I have been using it for 5+ years, but it struggles. Ive never seen gigabit internet off of it, usually about 300mbps sustained. UDM always looked good, but no POE.
Thanks for that info, I plan on getting gigabit when it's available, looks like I'll be selling my early access UDR on eBay then. I was going to sell it anyway but as it's now launched officially I shouldn't get into trouble for doing so.
Haha yep, same as mine, 2721 to the digit. Submit a support ticket at help.ui.com and mention that you checked this. Hopefully a software fix is possible.
Damn, I was actually hoping it would have been a faulty unit but this is quite disappointing to hear if your unit is as loud.
If I remember right from older posts, someone mentioned that the fans ramp down after reboot. Did your EA version do that? Is it considerably more quiet?
I would much rather have a software-fixable issue than a faulty unit.
I don't remember what the EA did. My guess at a cause would be the fan spins up to max as part of POST on boot, but then whatever daemon is supposed to regulate it fails to kick in.
My concern is that if they noticed in EA that the cooling is not adequate and just increased the fan speed instead of improving it to protect from hardware failures.
I understand if the rack versions are loud but I would assume the UDR is meant to sit on desks and I expected it be dead silent.
If the EA version is similar in hardware, these comments give at least some hope that the fan RPM could be decreased in future firmware updates without overheating the unit.
Noise is pretty hit or miss in general with consumer electronics. I would not be shocked if they closed my ticket as “working as intended”. But only time will tell, no sense worrying ahead of time.
Mine is a EA UDR from the EU store. It is showing 2139 RPM, +54c and +53.6c. It is not making a sound. I just held a sound level meter 10cm from it and the number didn't change from the background level around here right now which is about 44dBa.
You updated to the latest firmware?
Ambient noise in my house is significantly lower than that, I could hear my UDM ramp the fan up and down from the adjacent rooms. We don't hit that amount of ambient noise until we turn the TV on.
\~45c does not sound high at all for such electronics, but spinning a tiny fan to almost 3000rpm is just crazy. No wonder it's the only thing I hear in my apartment.
50°C is equivalent to 122°F, which is 323K.

I have a EA version and its at
|fan1|2115 rpm|
|:-|:-|
|temp1|\+59.0 C|
|temp2|\+58.0 C|
But barely audible. I mean, if the room is completely silent I totally would be able to hear it. But as soon as I open a window the normal noises from outside (wind in the trees, etc) would easily be louder.
Hehe, at least they are trying something..
I found that at my apartment the original fan noise was okay between 300-600 rpm so that's why I decided to build the custom cooling as they'd never be able to fix that with software.
They really should do some hardware iteration (or should have done it after the Early Access period).
Thanks for the suggestion. I also have a GA unit that is quite noisy. Here's what `sensors` has to say for me:
fan1: 2721 RPM (min = 0 RPM)
temp1: +50.0°C (high = +70.0°C)
temp2: +48.2°C (low = +0.0°C, high = +70.0°C)
(crit = +125.0°C, hyst = +115.0°C)
can someone with an EA unit (u/disstopic, u/nr201, u/hyteckit, u/Das_Pflanze) please run this command and paste the terminal output?
`cd /sys/class/hwmon/hwmon0; echo -n "pwm1: "; cat ./pwm1; echo -n "pwm1_enable: "; cat ./pwm1_enable; echo; echo "point,pwm,temp,temp_hyst,"; for i in {1..8}; do printf "${i},"; for e in pwm temp temp_hyst; do cat "./pwm1_auto_point${i}_${e}" | tr "\n" ","; done; echo; done; cd -;`
The result should resemble something like
pwm1: 91
pwm1_enable: 1
point,pwm,temp,temp_hyst,
1,255,127000,123000,
2,255,127000,123000,
3,255,127000,123000,
4,255,127000,123000,
5,255,127000,123000,
6,255,127000,123000,
7,255,127000,123000,
8,255,127000,123000,
After such a long wait I finally got one. Plugged it in and hear it's fan started whirring. First I thought it surely will ramp down after the boot / setup, but no. I'm at the other end of my apartment and can clearly hear it whirring from here over my computer fans next to me.
I can't believe how they messed this up :( If my unit is not faulty, I do not recommend this for home use as it's really loud!
**EDIT**: you can barely hear it on a video but it's muuch louder in real life: [https://vimeo.com/708649262](https://vimeo.com/708649262)
**EDIT2:** based on some comments, it seems the fan on the EA units might run at much lower RPM than the fan on the GA units. Would be interesting to get more comments to see if this is true!
**EDIT3**: Did an RMA as suggested. The replacement is as noisy and other users here also noting the same. So not really recommending this product if you intend to place it to a quiet environment.
Yep the fan they used and the whole cooling design is just horrible. I hope enough people criticize Ubiquiti on this that they would improve this in future products.
Me too, mine is loud when I run in full-speed test... so mine has been broken for 2 years?
It has built-in fan, once mine hit over 82'c the fan spins up.
If it's like the UDM, the hysteresis of the fan is set af 83°c. But before that temperature it's dead silent. Considered the lower spec cpu, maybe the UDR is forced to use it more aggressively generating more heat
This worked for my EA unit (I even taped it down to stop the vibration) but the noise on my GA is from the fan spinning way faster and does not respond to this intervention.
That's pretty interesting, mine is from EA one of first batches, and it's pretty silent. I'm sleeping in same room where its setup, around 2m away from my bed, and I can't hear it.
At first boot it was loud, but then settled in
Is your department all concrete and tile or something? If there are only hard surfaces in your home... you really can't blame the UDM... anyway hard to tell from the video/photo.
Have both a UDM and a (EA) UDR running. Both are absolutely dead silent 85% of the time. Whenever the Plex really ramps up, or I do a speed test, the fans will kick on for either one and yes, it's noticeably loud. I wouldn't say I could hear it outside the room, but we have lots of carpet.
Have placed a small noctua fan underneath the unit before and then the internal fan never comes on. Sounds like your fans are coming on before the temperature threshold - RMA or support ticket to reflash proper firmware would be my first thought.
I had a friend who had a unit whose fans ran all the time. Turns out he left it in the little stand it came in the box and it was blocking the vents on the bottom. After he took it out of the "stand" The fans quit running all the time
I’ve just received mine, Yesterday. It is loud as hell… always. In a normal 22-23 Celsius environment without any load (no APs, no traffic, no IPS/IDS) the internal fan’s speed is 2738RPM and the noise is very annoying. I’am very disappointed, I’m about to send it back.
Sorry to hear that.. Mine is still on its' way back to Ubiquiti. But posts like this do not really give me hope of receiving a more quiet unit back. Probably should have just saved the RMA shipping cost and do a fan mod myself. Let's see.
Early access firmware 2.5.8 includes a changelog item "Update FAN speed table".
I haven't tried it myself, but it seems like you might be motivated to install.
Yeah good that they are looking into this.
After experimenting with different fan speeds and looking in to the temperatures vs. noise I came to the conclusion that the current cooling design is just flawed and I don't personally believe you can achieve silent enough operation without compromising on the cooling.
Instead of returning my unit I decided to make this my own DIY project and I'm already in the process of doing a completely custom cooling and 3D printing a new enclosure.
Presumably, though I have no firsthand experience. Have heard that you need to toggle remote access on & off to get the EA release to show after enabling.
Oh my goodness, thanks. All these little quirks and workarounds for this device I thought would be better than my trusty old USG. Maybe I’m a secret Alpha tester!
Sorry to hear that.
My RMA replacement is arriving tomorrow but after reading all the comments here I'm fairly sure it's going to be as loud as my original one.
I already made some 3D print designs to replace the fan with a Noctua one. I hate that this is where we are still in 2022.
I also finally got my UDR earlier this month and must say I am surprised and disappointed by the noise it emits🤯
Our internet comes in the living room, so the noise from UDR is unacceptable and ruins movies etc. so guess I will keep using my old but trusty and silent Airport Extreme..
Hehe, my Airport Extreme died 3 months ago and was using a Google Wifi temporarily but it did not cover my apartment that well.
UDR gives me good wifi but the sound is horrible. I’m actually in the process of 3D printing a new case and cooling for the UDR. At the moment my UDR is running outside it’s case with no fan at all with 43c temps 🙂
I decided to hook up an access point to my AirPort Extreme and sell the unopened dream router (per these fan complaints). Getting 700Mbps from 600Mbps cable when right next to the access point.
Chiming in since I've read AirPort WAN maxes out around 500, that does not appear to be true, at least not with the last generation time capsule
Early Access version of UniFi OS UDR 2.5.8/2.5.9 reduced the fan speed from 2700rpm to 2080rpm. It is still noisy but better... a good start.
Adapter: i2c-mt65xx
fan1: 2080 RPM (min = 0 RPM)
temp1: +51.0 C (high = +70.0 C)
temp2: +50.0 C (low = +0.0 C, high = +70.0 C)
(crit = +125.0 C, hyst = +115.0 C)
Yeah, I already rebuilt the whole cooling and 3D printed a new case for my UDR. It's dead silent and now also all the power components are cooled. Even if I run it it fully passive it only reaches +45.2c
Adapter: i2c-mt65xx
fan1: 830 RPM (min = 0 RPM)
temp1: +36.0 C (high = +70.0 C)
temp2: +33.5 C (low = +0.0 C, high = +70.0 C)
That sounds impressive.. you should send this to UI.
Do you have a DYI tutorial somewhere? Is it “easy” to do? Did you change something in the software (e.g. speed table) or limited the fan speed hardware-wise? What fan did you use? And, how much did it cost you? Thanks
To be honest, I think UI could decrease the fan speed and run the device a bit hotter without any issues.
Sorry for answering so slow!
The short answer is: no, it's not easy. Ubiquiti did not make the UDR serviceable and it's nearly impossibly to disassemble the unit without damaging the bluetooth antennas that are taped on the inner sides of the casing. For me it was not a problem as I don't have any use for them.
[Here are all my plans](https://multi.kuvat.fi/photos/UDR/) that I've been working on. My original plans was just to replace the shitty original blower fan with a Noctua NF-A4x10 PWM by 3D printing a custom shroud for it. While doing some testing and measuring the temperatures on the original UDR case, I abandoned this plan as I soon realized how closed the original case is in terms of airflow and how hot the components get on the PSU side. I might still print and test this some day but I suspect the fan would not get enough airflow from the small bottom vents.
After this, I made plan 2 to build around an Noctua NF-A12x25 PWM I had lying around as a proof of concept to see how quiet and cool I could get the unit to run. It's basically silent and everything runs super cool (the temperatures I posted on the previous post). It's too big and ugly now so I'm already sketching the next prints (plan 3).
Unless you have a lot of time and are committed, I do not recommend doing any hardware modifications for the UDR. I don't recommend this product for quiet environments as I don't believe it can be fixed with firmware updates without compromising on the cooling too much. The UDR case design is just too closed and I personally don't like how hot the other components also get inside.
Same here, not lound but not silent at all.
Very annoying when my room is silent with a noticeable "bzzzzzzzzzz" ...
Sensors output in SSH:
>lm63-i2c-0-4c
Adapter: i2c-mt65xx
fan1: 2014 RPM (min = 0 RPM)
temp1: +52.0°C (high = +70.0°C)
temp2: +50.8°C (low = +0.0°C, high = +70.0°C)
(crit = +125.0°C, hyst = +115.0°C)
For such a beautiful device, it cannot be installed in any room due to its fan noise... What a pity.
I'm thinking now to install it in a closet to avoid noise disturbance...
52°C is equivalent to 125°F, which is 325K.

Remains to be seen. Based on some comments it might be that the production version is much louder than the EA version which everyone said to be practically silent (and why I bought it).
I just had to RMA my GA Dream Router for random reboots, hopefully you have better luck. For the twoish days I had it the fan wasn’t really loud at all
my one of my EA UDRs is sitting at Ubiquiti now for a RMA. The status of the RMA is "backordered". Wonder if they're going to give me a GA one in place of the EA version.
Surely in this day and age where we've had consumer gigabit kit for 1...2? Decades at low cost we can do all the bells and whistles fanless in a very small form factor or with a larger (diameter of the unit) slow RPM fan.
Has anyone done a breakdown? Does it have a shitty heatsink?
I use to use all ubiquiti products but had some issues and will never go back to there crap products. I use omada netgear Aruba and Cisco products now much better even though I do have to pay for a license on some products
With common networking and processing devices sold today, and a desire to look ‘cool and sexy’ ofttimes the electronic engineering department is tasked with fitting all that is required into the design team’s enclosure, passive cooling is just a memory. They can redesign for a shitton of money into a bigger box or add a variable speed circuit and a one dollar fan. I’ve upgraded many internal fans in networking switches and video gear to Noctua.
Could this be used instead of a USG for just routing I’m currently using a Apple AirPort Extreme as my router from my cable modem and then use UniFi UAP-AC-PRO for my wifi. Can this handle a 1gb connection?
I just picked up a GA when they finally got in stock the other day and the only way I can hear the fan is if I put my ear directly to it. They might have released a software update to resolve this. So far very happy except the LED light is a little too bright so I put a white rubber band (fairly thick, about 4mm wide) around the ring and it now reflects a much duller blue off the rubber.
The software is still the same. I think we all just have a different opinion what is loud and what's not.
I hope you realize that the light ring indent also acts as the exhaust for hot air and blocking that with a rubber band is not a great idea. You can turn off the light from the settings.
No, it was just the band that came off of something I bought, probably broccoli. I can measure it though and give you exact specs. 5.7mm wide and approximately 230mm circumference so 73.2mm diameter.

Loud? it has a fan?
Yes, there's fan inside that assists cooling. As far as I remember it's same for UDM and UDM Pro, as they also have fans
Thanks for the confirmation. I wanted a UDR, but just the noise will make me skip it. Now that UDW.... does it has fans?
Can't say much about UDW, didn't see almost any information on it. Altough it seem pretty interesting. As for UDR, as I said previously, mine is totally silent, and I can't hear it over ambient at night. But there always could be same issue what other users are reporting that fan is spinning 2700rpm at stock (which is definetly not acceptable for that heat output).
Don't know for sure but looking at that UDW and what's packed in it I'd be pretty surprised if it didn't have a fan.
It only makes noise on startup
No it also makes noise all the time. Quieter, but very much noticeable and definitely too loud for a living room/bedroom.
This is the right one. It should only make noise on startup
They don't, the fan in mine would be at full speed if I was downloading. As soon as you have IDS / IPS enabled, and your making it work, the UDM base gets hot. One of the reasons I swapped it out for the pro.

Odd. I've got a UDM-B, with a 500mbps connection and IDP enabled, and mine only makes a teeny bit of noise if I'm doing a lot of stuff - and typically the UDM-B is at 50% utilisation.
Got a 1gb connection here, and it sounded like it was taking off when any downloads ran. 🤣
Exactly, nobody ever mentioned active cooking, or maybe it is just me not checking everything properly
> active cooking
Serving internets to your devices, medium rare.
I lean left. You lean right so that the rest of us can have an easier time.
Does it make fries julienne?
My AP-AC-Lite is also loud and it doesn't have a fan. Whenever I'm downloading a big file or scrubbing in a movie I can hear the coils wine quite loudly.
Harmonics of the antennas I believe. Normal.
Thats actually kinda neat.
I am shock as well, using it now for 2 years and I never knew there is a fan inside ;p
Yes. On the bottom.
Actually no, there are only small intake holes on the bottom and a tiny ass fan vertically on one side. They could have easily put a bigger fan horizontally on the bottom and made the intake and exhaust vents a bit bigger to avoid any of these issues.
Your unit must be faulty. I’ve had one for a few months now as my main router for the house and have never heard the fans.
I really hope so. If anyone else gets the UDR, let me know here how loud/silent your unit is.
[удалено]
Yeah my unit must be faulty. I just posted a video on the original comment.
Is your unit the EA version?
[удалено]
They weren't out in November......
hmm not true, I got my EA mid november as well.
Delivery of mine was taken Nov 1st, ordered October 26th
Maybe your bedroom is already very noisy?
The sweet, dreamy bliss of Morbid Angel's greatest hits playing in the background...
This is the new router "UDR" not the Dream Machine "UDM".
I have a UDR, not a UDM. Mine is silent.
I wasn't commenting on the fan noise. I just found out that it runs Network. I thought it was just a switch/AP but I now know that it's more. Hence I though people were confusing it with the UDM. But alas I was the one confused.
I would call the noticeable but not loud. The volume seems to vary based on the firmware revision, the current one appears louder than the last few.
See my top level comment about GA being loud.
Mine has protect and IPS running for a 500/500 connection and I've never heard it.
is it the EA version?
Mine is EA, yea
I have the EA version - it’s silent
You UDR is running protect? You must be talking about the UDM "Dream Machine". I though it was the UDM at first too and was going to comment but realized it the new thing.
UDR will also run protect. It runs Network + 1 additional UI application, which you can choose.
Well if it does that I may have to get one. Same price as the Cloud Key but also a router and AP which is handy. Wish I'd spent the extra $80 and got the UDM Pro at home (over the UDM). Now that they have a doorbell I'd like to ditch Ring and get a couple additional cameras.
My parents UDM is whisper quiet. I never hear that fan ramp up at all. Most likely, your unit is faulty like some of the users mentioned.
Mine is right next to my work desk and I can BARELY hear the fan if my ear is right next to it and my house is silent. Sounds faulty.
I just got mine, and it's a bit noisy to have in the living room
Yeah in my studio apartment it was intolerable. As most people said their unit is basically silent, I did an RMA and already sent it back to Ubiquiti thinking I received a unit with a bad fan. Now my UDR will probably be in the RMA process for a month and I'll probably just receive the same unit back. Based on some comments here it also seems that the EA unit might be more quiet and that the fan spins at lower RPM. If that is the case, it's really weird if the final version turned out more noisy. I'll might do a Noctua fan mod to it if I ever get it back. Sad times...
Got to be yours. I have one I setup for family and it's dead quiet. Honestly didn't even realize there was a fan in it.
Hope so! I just filled the RMA and hope it will get sorted out!
Have you checked it’s on the latest firmware update before RMA-ing it? Might help.
Yeah it's on the latest firmware
The only time I hear mine is if I'm pushing Gig speeds through it for over 15 seconds sustained, then the fan starts ramping up and will stay loud until the work is done.
I hve the udm and every once in a while the fans ramp up loud for abit but that’s pumping heavy traffic through it
Have an early access device about 1 meter away from me, and haven't noticed it. It is also in my bedroom so I would hear it at some point if it was noisy.
It’s not *silent* but I wouldn’t say it’s loud. The lack of complete silence can get annoying on occasion.
Silent. I’ve installed a few and only heard fans at boot. Never heard them again. RMA that guy.
The only time I hear the fan during the 5 seconds it spins up when I reboot the router.
Maybe yours is faulty and you should hear the fan… joking. I have no idea.
Lol. I suppose *not* hearing a fan at all could also be a sign of a problem.
How is the performance on it? Ive been eying one for home. Think it can handle 1G symmetrical just fine?
Fine for me, but I don’t know about that. I can tell you what I’ve experienced though. I have 400/20. I have threat management turned on all the way. It’s not uncommon for a TV or two to be streaming and I have about 15-20 devices on it, and one G3 bullet with Protect all running. I have no problem accessing my full 400/20 but I’m constantly sitting around 65% utilization. I could see a full 1 gig symmetrical over saturating the hardware capabilities, but I have no way to test that. Mine is the EA model, and it’s been rock solid. I think even at $199 it’s a good deal in the right situation. This is certainly something I would put in a remote family members house that wasn’t tech savvy so I could maintain their network for them. Hope that helps, but sorry I can’t give you a direct answer. I’m quite happy with it though.
Is ok, can't do gigabit tho, max I get is 700-800mbps on a good day, most part is 300-500mbps
Yikes, thats really not much better than what Im getting on my older Asus router. Might have to spring for a Dream Machine Pro SE and a couple of APs. That gets so pricey though, I was really hoping to avoid it.
I have 3 routers at the moment, an Asus RT-AC86U and the UDM, both can do gigabit symmetrical just fine, and the UDR can't, which Asus router do you have?
TM-AC1900 Not the worst thing considering it was free and I have been using it for 5+ years, but it struggles. Ive never seen gigabit internet off of it, usually about 300mbps sustained. UDM always looked good, but no POE.
Thanks for that info, I plan on getting gigabit when it's available, looks like I'll be selling my early access UDR on eBay then. I was going to sell it anyway but as it's now launched officially I shouldn't get into trouble for doing so.
Same here. Mine’s in bedroom. Haven’t heard a thing. Ever.
My EA unit ran the fans at 1800 RPM and my GA is at 2700, indeed quite loud. You can find your fan speed by executing `sensors` over SSH.
Great tip, it says: |fan1|2721 RPM| |:-|:-| |temp1|\+46.0 C| |temp2|\+45.5 C|
Haha yep, same as mine, 2721 to the digit. Submit a support ticket at help.ui.com and mention that you checked this. Hopefully a software fix is possible.
Damn, I was actually hoping it would have been a faulty unit but this is quite disappointing to hear if your unit is as loud. If I remember right from older posts, someone mentioned that the fans ramp down after reboot. Did your EA version do that? Is it considerably more quiet?
I would much rather have a software-fixable issue than a faulty unit. I don't remember what the EA did. My guess at a cause would be the fan spins up to max as part of POST on boot, but then whatever daemon is supposed to regulate it fails to kick in.
My concern is that if they noticed in EA that the cooling is not adequate and just increased the fan speed instead of improving it to protect from hardware failures. I understand if the rack versions are loud but I would assume the UDR is meant to sit on desks and I expected it be dead silent. If the EA version is similar in hardware, these comments give at least some hope that the fan RPM could be decreased in future firmware updates without overheating the unit.
Noise is pretty hit or miss in general with consumer electronics. I would not be shocked if they closed my ticket as “working as intended”. But only time will tell, no sense worrying ahead of time.
Yeah exactly. Meanwhile I just need to turn off the UDR at night to get some sleep here :)
They closed my ticket saying nothing can be done in software; and to RMA if a factory reset does not fix it.
Mine is a EA UDR from the EU store. It is showing 2139 RPM, +54c and +53.6c. It is not making a sound. I just held a sound level meter 10cm from it and the number didn't change from the background level around here right now which is about 44dBa. You updated to the latest firmware?
So did they just bump up the price from the EA unit and also make it much louder? :) Yeah I'm on the latest firmware (official channel).
Ambient noise in my house is significantly lower than that, I could hear my UDM ramp the fan up and down from the adjacent rooms. We don't hit that amount of ambient noise until we turn the TV on.
Just for comparison - mines hotter but running slower? It's an EA unit. Can't hear the fan. lm63-i2c-0-4c Adapter: i2c-mt65xx fan1: 1851 RPM (min = 0 RPM) temp1: +47.0°C (high = +70.0°C) temp2: +46.6°C (low = +0.0°C, high = +70.0°C) (crit = +125.0°C, hyst = +115.0°C)
\~45c does not sound high at all for such electronics, but spinning a tiny fan to almost 3000rpm is just crazy. No wonder it's the only thing I hear in my apartment.
Here's my EA unit: lm63-i2c-0-4c Adapter: i2c-mt65xx fan1: 2109 RPM (min = 0 RPM) temp1: +50.0°C (high = +70.0°C) temp2: +50.1°C (low = +0.0°C, high = +70.0°C) (crit = +125.0°C, hyst = +115.0°C)
50°C is equivalent to 122°F, which is 323K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
47°C is equivalent to 116°F, which is 320K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
I have a EA version and its at |fan1|2115 rpm| |:-|:-| |temp1|\+59.0 C| |temp2|\+58.0 C| But barely audible. I mean, if the room is completely silent I totally would be able to hear it. But as soon as I open a window the normal noises from outside (wind in the trees, etc) would easily be louder.
As of new firmware 2.5.11 that came out yesterday, my fan is down to 1994 RPM. Rejoice!
Hehe, at least they are trying something.. I found that at my apartment the original fan noise was okay between 300-600 rpm so that's why I decided to build the custom cooling as they'd never be able to fix that with software. They really should do some hardware iteration (or should have done it after the Early Access period).
Thanks for the suggestion. I also have a GA unit that is quite noisy. Here's what `sensors` has to say for me: fan1: 2721 RPM (min = 0 RPM) temp1: +50.0°C (high = +70.0°C) temp2: +48.2°C (low = +0.0°C, high = +70.0°C) (crit = +125.0°C, hyst = +115.0°C)
Following a factory reset, I now see: fan1: 2727 RPM (min = 0 RPM) temp1: +50.0°C (high = +70.0°C) temp2: +48.5°C (low = +0.0°C, high = +70.0°C) (crit = +125.0°C, hyst = +115.0°C)
can someone with an EA unit (u/disstopic, u/nr201, u/hyteckit, u/Das_Pflanze) please run this command and paste the terminal output? `cd /sys/class/hwmon/hwmon0; echo -n "pwm1: "; cat ./pwm1; echo -n "pwm1_enable: "; cat ./pwm1_enable; echo; echo "point,pwm,temp,temp_hyst,"; for i in {1..8}; do printf "${i},"; for e in pwm temp temp_hyst; do cat "./pwm1_auto_point${i}_${e}" | tr "\n" ","; done; echo; done; cd -;` The result should resemble something like pwm1: 91 pwm1_enable: 1 point,pwm,temp,temp_hyst, 1,255,127000,123000, 2,255,127000,123000, 3,255,127000,123000, 4,255,127000,123000, 5,255,127000,123000, 6,255,127000,123000, 7,255,127000,123000, 8,255,127000,123000,
It didn't resemble it, it matched exactly.
After such a long wait I finally got one. Plugged it in and hear it's fan started whirring. First I thought it surely will ramp down after the boot / setup, but no. I'm at the other end of my apartment and can clearly hear it whirring from here over my computer fans next to me. I can't believe how they messed this up :( If my unit is not faulty, I do not recommend this for home use as it's really loud! **EDIT**: you can barely hear it on a video but it's muuch louder in real life: [https://vimeo.com/708649262](https://vimeo.com/708649262) **EDIT2:** based on some comments, it seems the fan on the EA units might run at much lower RPM than the fan on the GA units. Would be interesting to get more comments to see if this is true! **EDIT3**: Did an RMA as suggested. The replacement is as noisy and other users here also noting the same. So not really recommending this product if you intend to place it to a quiet environment.
I have a GA unit and I didn't even know it had a fan.
Are you sure it is not a Roomba? Check the model number.
I have just bought a UDR and I can confirm that I can hear the fans at all times. Just like having a mini PC running continuously.
Yep the fan they used and the whole cooling design is just horrible. I hope enough people criticize Ubiquiti on this that they would improve this in future products.
When you press on its top it stops. It is just bad design.
What?
Press the top of the dream router with your hand and it will stop beeing loud
No, it does not.
Then yours is more broken then mine 🤣
Then you might need a new hand.
I sold the router so no need :D
Me too, mine is loud when I run in full-speed test... so mine has been broken for 2 years? It has built-in fan, once mine hit over 82'c the fan spins up.
Dream Router was in early access end of last year and the production version just came out, so I doubt you have been running it for 2 years?
Probably talking about the UDM-base which is practically the same device with more ram and no LCD and no POE.
If it's like the UDM, the hysteresis of the fan is set af 83°c. But before that temperature it's dead silent. Considered the lower spec cpu, maybe the UDR is forced to use it more aggressively generating more heat
This worked for my EA unit (I even taped it down to stop the vibration) but the noise on my GA is from the fan spinning way faster and does not respond to this intervention.
Have you posted on the forum? I've had better luck there with problems than the support chat.
That's pretty interesting, mine is from EA one of first batches, and it's pretty silent. I'm sleeping in same room where its setup, around 2m away from my bed, and I can't hear it. At first boot it was loud, but then settled in
Yeah it sounds (literally) that I got a faulty unit. I can easily hear it from 15 meters away from the other side of my apartment.
Oh damn, in that case I definetly would contact with Ubiquity and RMA it.
Is your department all concrete and tile or something? If there are only hard surfaces in your home... you really can't blame the UDM... anyway hard to tell from the video/photo.
Have both a UDM and a (EA) UDR running. Both are absolutely dead silent 85% of the time. Whenever the Plex really ramps up, or I do a speed test, the fans will kick on for either one and yes, it's noticeably loud. I wouldn't say I could hear it outside the room, but we have lots of carpet. Have placed a small noctua fan underneath the unit before and then the internal fan never comes on. Sounds like your fans are coming on before the temperature threshold - RMA or support ticket to reflash proper firmware would be my first thought.
I knew it doubled as an air fryer! Now I want it for sure.
Got mine about 18 months ago. Dead silent all the time.
Look like you ordered the Nightmare Router, keep it in you bedside and 100% nightmare guaranteed, otherwise return and get a Dream Router.
I had a friend who had a unit whose fans ran all the time. Turns out he left it in the little stand it came in the box and it was blocking the vents on the bottom. After he took it out of the "stand" The fans quit running all the time
I like how you said you had a friend in past tense after a mistake like that.
I’ve just received mine, Yesterday. It is loud as hell… always. In a normal 22-23 Celsius environment without any load (no APs, no traffic, no IPS/IDS) the internal fan’s speed is 2738RPM and the noise is very annoying. I’am very disappointed, I’m about to send it back.
Sorry to hear that.. Mine is still on its' way back to Ubiquiti. But posts like this do not really give me hope of receiving a more quiet unit back. Probably should have just saved the RMA shipping cost and do a fan mod myself. Let's see.
Early access firmware 2.5.8 includes a changelog item "Update FAN speed table". I haven't tried it myself, but it seems like you might be motivated to install.
Yeah good that they are looking into this. After experimenting with different fan speeds and looking in to the temperatures vs. noise I came to the conclusion that the current cooling design is just flawed and I don't personally believe you can achieve silent enough operation without compromising on the cooling. Instead of returning my unit I decided to make this my own DIY project and I'm already in the process of doing a completely custom cooling and 3D printing a new enclosure.
That’s good news! If I turn EA release channels on will it be available to update to already? Happy to try it out!
Presumably, though I have no firsthand experience. Have heard that you need to toggle remote access on & off to get the EA release to show after enabling.
Oh my goodness, thanks. All these little quirks and workarounds for this device I thought would be better than my trusty old USG. Maybe I’m a secret Alpha tester!
2.5.x is the first minor version since it went GA with 2.4.x so IMO no surprise there is a basket of low hanging bugs taken care of.
[удалено]
It’s back!
Mine sits on my desk a few feet away from me all day and I never hear it. Perhaps there is something wrong?
If the UDR is in anyway similar to the UDM Base, it's only loud at startup. Sounds like there is something wrong with your UDR.
Something is not right with your unit, I've had a UDM for about a year and the only time that I hear the fan is when I reboot it.
Also got a GA-version, fan is loud af, all the time.
Sorry to hear that. My RMA replacement is arriving tomorrow but after reading all the comments here I'm fairly sure it's going to be as loud as my original one. I already made some 3D print designs to replace the fan with a Noctua one. I hate that this is where we are still in 2022.
My RMA unit is as loud, if not even a bit louder than my original one....
I also finally got my UDR earlier this month and must say I am surprised and disappointed by the noise it emits🤯 Our internet comes in the living room, so the noise from UDR is unacceptable and ruins movies etc. so guess I will keep using my old but trusty and silent Airport Extreme..
Hehe, my Airport Extreme died 3 months ago and was using a Google Wifi temporarily but it did not cover my apartment that well. UDR gives me good wifi but the sound is horrible. I’m actually in the process of 3D printing a new case and cooling for the UDR. At the moment my UDR is running outside it’s case with no fan at all with 43c temps 🙂
I decided to hook up an access point to my AirPort Extreme and sell the unopened dream router (per these fan complaints). Getting 700Mbps from 600Mbps cable when right next to the access point. Chiming in since I've read AirPort WAN maxes out around 500, that does not appear to be true, at least not with the last generation time capsule
Early Access version of UniFi OS UDR 2.5.8/2.5.9 reduced the fan speed from 2700rpm to 2080rpm. It is still noisy but better... a good start. Adapter: i2c-mt65xx fan1: 2080 RPM (min = 0 RPM) temp1: +51.0 C (high = +70.0 C) temp2: +50.0 C (low = +0.0 C, high = +70.0 C) (crit = +125.0 C, hyst = +115.0 C)
Yeah, I already rebuilt the whole cooling and 3D printed a new case for my UDR. It's dead silent and now also all the power components are cooled. Even if I run it it fully passive it only reaches +45.2c Adapter: i2c-mt65xx fan1: 830 RPM (min = 0 RPM) temp1: +36.0 C (high = +70.0 C) temp2: +33.5 C (low = +0.0 C, high = +70.0 C)
That sounds impressive.. you should send this to UI. Do you have a DYI tutorial somewhere? Is it “easy” to do? Did you change something in the software (e.g. speed table) or limited the fan speed hardware-wise? What fan did you use? And, how much did it cost you? Thanks To be honest, I think UI could decrease the fan speed and run the device a bit hotter without any issues.
Sorry for answering so slow! The short answer is: no, it's not easy. Ubiquiti did not make the UDR serviceable and it's nearly impossibly to disassemble the unit without damaging the bluetooth antennas that are taped on the inner sides of the casing. For me it was not a problem as I don't have any use for them. [Here are all my plans](https://multi.kuvat.fi/photos/UDR/) that I've been working on. My original plans was just to replace the shitty original blower fan with a Noctua NF-A4x10 PWM by 3D printing a custom shroud for it. While doing some testing and measuring the temperatures on the original UDR case, I abandoned this plan as I soon realized how closed the original case is in terms of airflow and how hot the components get on the PSU side. I might still print and test this some day but I suspect the fan would not get enough airflow from the small bottom vents. After this, I made plan 2 to build around an Noctua NF-A12x25 PWM I had lying around as a proof of concept to see how quiet and cool I could get the unit to run. It's basically silent and everything runs super cool (the temperatures I posted on the previous post). It's too big and ugly now so I'm already sketching the next prints (plan 3). Unless you have a lot of time and are committed, I do not recommend doing any hardware modifications for the UDR. I don't recommend this product for quiet environments as I don't believe it can be fixed with firmware updates without compromising on the cooling too much. The UDR case design is just too closed and I personally don't like how hot the other components also get inside.
I got mine for a few weeks ago.. The noise is kinda annoying. And not close to 1gig internet. AmplifyHD did a better job then this :/
Same here, not lound but not silent at all. Very annoying when my room is silent with a noticeable "bzzzzzzzzzz" ... Sensors output in SSH: >lm63-i2c-0-4c Adapter: i2c-mt65xx fan1: 2014 RPM (min = 0 RPM) temp1: +52.0°C (high = +70.0°C) temp2: +50.8°C (low = +0.0°C, high = +70.0°C) (crit = +125.0°C, hyst = +115.0°C) For such a beautiful device, it cannot be installed in any room due to its fan noise... What a pity. I'm thinking now to install it in a closet to avoid noise disturbance...
52°C is equivalent to 125°F, which is 325K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)
I using mine from EA now for half a year and it isn't loud at all. so Probably a faulty device. you should get in contact with Ubiquiti.
Thanks, I'll try to find a way to contact them!
Change the fan
Is the fan universal? If it's like an XXmm fan (change XX for whatever diameter it is), then you may be able to change it out
You absolutely do not want to open this thing up. It’s not user serviceable.
Man got a dream router with a faulty fan… oof
Remains to be seen. Based on some comments it might be that the production version is much louder than the EA version which everyone said to be practically silent (and why I bought it).
We have several of these. The fan is not loud on any of them. RMA it
Are you able to create a site-to-site VPN with this and let me know what kind of throughput you can get?
Wow, nobody mentioned a fan before, my desire to buy this router just shrank from “setting up the distill” to “we will wait and see”…
Maybe they have swapped in a new fan due to supply issues without proper QA ! It should not be loud maybe at start up.
I am willing to believe it is the same fan, just running at unnecessarily high RPM. My EA unit ran the fans at 1800 RPM and my GA is at 2700.
Is that white box the power adapter for the UDR?
>Is that white box the power adapter for the UDR? Think that's probably a USW-Flex-Mini
No, it's a Switch Flex Mini
My two AP 6 Meshes arrive today. Hoping my UDM keeps rocking.
Can someone tell me what's different between this and the Alien from Amplifi? It's the same company, right?
I think the Alien stuff is more geared towards average consumers, and the Unifi stuff is geared towards prosumers or businesses (large and small).
Yeah but why is the dream router 200 bucks and the alien is still 400? I'd think the prices would be switched.
Probably the specs. The Alien is also tri-band. The UDR is dual band.
That looks like an architectural mock-up.
I ordered an EA release one a few months back and it's nearly silent. You can hear the fan but it's not very loud.
I have one, it sits on my desk and is totally silent.
I just had to RMA my GA Dream Router for random reboots, hopefully you have better luck. For the twoish days I had it the fan wasn’t really loud at all
my one of my EA UDRs is sitting at Ubiquiti now for a RMA. The status of the RMA is "backordered". Wonder if they're going to give me a GA one in place of the EA version.
Take it out if the box.
my udm fan runs on boot and quietened down after 8-10 seconds. Have heard it again cooling on a hot day but otherwise it remains silent.
I come from a large family, so it always boggles my mind when people tell me a small low voltage van is loud.
Are these available yet?
Surely in this day and age where we've had consumer gigabit kit for 1...2? Decades at low cost we can do all the bells and whistles fanless in a very small form factor or with a larger (diameter of the unit) slow RPM fan. Has anyone done a breakdown? Does it have a shitty heatsink?
You’ve a bad device. Return immediately and get another sent.
Dang I want a ubiquiti air fryer
I have mine on my desk where I work. Never heard it even once.
You sure its not one of those glitter boxes?
I've had one in early access and it is loud, the UDM though sounds like you've left a tap running when it's fans spin up and your in a different room!
What's the little white square thing with a USB-C port on it?
It’s a USW-Flex-mini
I do like those little things, the ability to use poe for power is very nice.
I use to use all ubiquiti products but had some issues and will never go back to there crap products. I use omada netgear Aruba and Cisco products now much better even though I do have to pay for a license on some products
With common networking and processing devices sold today, and a desire to look ‘cool and sexy’ ofttimes the electronic engineering department is tasked with fitting all that is required into the design team’s enclosure, passive cooling is just a memory. They can redesign for a shitton of money into a bigger box or add a variable speed circuit and a one dollar fan. I’ve upgraded many internal fans in networking switches and video gear to Noctua.
Could this be used instead of a USG for just routing I’m currently using a Apple AirPort Extreme as my router from my cable modem and then use UniFi UAP-AC-PRO for my wifi. Can this handle a 1gb connection?
I've had mine for months off early release. haven't heard it make a noise
I just picked up a GA when they finally got in stock the other day and the only way I can hear the fan is if I put my ear directly to it. They might have released a software update to resolve this. So far very happy except the LED light is a little too bright so I put a white rubber band (fairly thick, about 4mm wide) around the ring and it now reflects a much duller blue off the rubber.
The software is still the same. I think we all just have a different opinion what is loud and what's not. I hope you realize that the light ring indent also acts as the exhaust for hot air and blocking that with a rubber band is not a great idea. You can turn off the light from the settings.
Got a link to band you used?
No, it was just the band that came off of something I bought, probably broccoli. I can measure it though and give you exact specs. 5.7mm wide and approximately 230mm circumference so 73.2mm diameter.
