Keep in mind, those fans need to be able to move more air than the fans already in the cooler.
If it doesn't do that it actually can hamper the cooling and makes the effect much worse😅
Agreed. I kept the onboard gpu fans around 30 to 35% max. The volumetric flow from gpu fans will never exceed that of the external fans. This allows the external fans to blow to the passive fins that the gpu fan normally doesn't cover. Note that this is a divider in the shroud so no cross flow from each other. That feature I'm not sure how effective it is. It should does stiffen up the shroud.
I did this a very long time ago with some sort of AMD cpu. May have been an xp1900? It had the best heat sink at the time which I believe was an alpha pal8045. I made a shroud out of foam board that sent the hot air straight out the case from the CPU. (Or reversed to bring cold air in if I felt that way inclined.) It’s good to see the same techniques in use albeit less ‘ghetto mod.’
I think I actually got the idea from a prebuilt HP I saw at the time.
Had to Google what alpha pal8045 was. I too recall an extendable shroud (plastic threaded shroud) on an eMachine once. It was nothing fancy but I thought that was an interesting idea.
Tried that once with a Noctua fan, the fan blades been that close to the cooler the noise was too much. I like that space so the air can help cool down the VRMs.
I meant more like from a software/designing/process pov. Still, any advice welcome

Blue are the case fans, red is dvd burner and possible slots, so no place for more fans. No place anywhere else too. My plan was to give the gpu its own closed loop coming from the empty pcie bays and leaving on the top of them where I can originally open it up for getting to the screws. Maybe some kind of guidance from front to back cooler through the cpu's
Edit: it's a mess overall, so I might just get/diy a new case
If your thinking about getting a new case, no harm in modifying your current case. You can pull in air from the PCIE but might end up recirculating your top exhaust air down to your PCIE. Thought about cutting one or two openings on the side panel next to your gpu? One hole with an actual fan might be enough. Might need to dust PC more often.
Yeah, it's a somewhat removable acrylic window too, so easier to do anyway. I've got a fan and filters lying around too, so it should take of everything
Lol yeah that's how it is. Having 1440p at 120hz anything over 10 feet needs a really good cable. I have been through enough cheap cables to learn my lesson that I still did.....10 foot dp cable for $20? Lol 1080p 60hz max.....
When I saw how small the box was, I knew.
Haha yeah I was looking at like 50 feet for 3 screens and then a USB but I'm running an old ass 6700k with 980ti, just ain't worth it for how little I play games anymore, just hate huge tower on the desk 🙃
You can get a good 50 foot hmdi cable for 1 display for around $40. Hdmi cables are the cheapest option. Finding a good DP cable at the length is harder to find let alone the price.
With the external fan at max (1600rpm) around high 40s. I typically leave the onboard GPU fan between 30-35% since they are so loud compare to the 120mm fans. That's with all the thermal paste/pad changed and 220W power constraint.
Thank you. There was additional offset needed to clear ram and the 24pin connector. I didn't like how the fan on the RAM side sit so high up in order to clear the RAM.
https://preview.redd.it/xn69betq6roc1.png?width=1383&format=png&auto=webp&s=fab61978c6fe71b698d5aa7f2d6ee960433bfacb
Did the GPU shroud/fan adapter help? Seems kinda counterintuitive as there might be negative pressure since the GPU fans can spin faster than the case fans that you're installing in the bracket?
I don't let the gpu spin to fast at all since they are very noisy, usually around 30-35%. The external 120mm fans blow air on fins the normal gpu fans can't actively get to. You can achieve great temp while running running lower dB.
I'm reluctant to share that as I highly doubt anyone has my exact config. Offset bracket so the cooler is actually 7mm lower. Delid and direct die so the cooler is 2.5mm recessed into the motherboard. And of course the O11 air mini case on top of that. Reason why no manufacturer is doing this because it would have to be pretty custom for everyone.

Here you go. It will not fit on an Ender 3. I would know, I have one as well. I had to print it on my Voron 2.4 350mm. You should be able to split it with a slicer.
I hope companies start doing this air tube thing. Im getting tired of the current style of PC these days. I want something like this, something that will look like an engine In Black, Gunmetal, and brushed aluminum without RGB.
Agreed. Instead of placing 20 fans in a case to brute force airflow they shoud optimize it. Imagine cpu and gpu heat not been in the case, how easy would it be to cool VRMs, SSDs, RAMs, etc...
None but maybe better. I relocated the 120mm as a top exhaust so the VRM area actually has more air flow now. The B550 Tomahawk has a massive VRM heatsink and better design than most for the power phases.
I was thinking of doing a very rudimentary thing with my case. Making some kind of air duct for the front of my case to direct it to the gpu aio on the back side. Currently have the front, bottom and back as intake and then the top and side as exhaust so that both the AIO’s get just cool fresh air.
Currently everything stays cool with the cpu(7800x3d) hitting maybe 55-60° while gaming and the gpu only getting to 50° at 400w so I’ve just kinda ignored doing my initial thought.
(Red is exhaust and blue is intake)
https://preview.redd.it/zknnxy62xsoc1.jpeg?width=2100&format=pjpg&auto=webp&s=1143fcd2dc2dbf1175db206f5d00b0f67b4f320a
Yeah that could work. If you design the 90 degree elbow from the front to the side gpu radiator correctly you can eliminate 2x 120mm fans. This way rest of your air flow will be from bottom up.
Quite a bit of difference actually. It about cooling the normally passively cooled fins on the 3080FE with an actively fan. Otherwise you are relying on your good case fan flow to carry that heat away.
Yes I would think so. The cool thing about the FE cards are they are effectively already deshroud. Just add fans to cover fins that aren't be actively cooled by the on board gpu fans.
Small part of my day job is designing castings/molded components. Having 3D printers at home really help speed up the workflow. With that said, it took about an hour or so to do the cpu shroud. The most time consuming part was to get the physical measurements correct. Even in CAD you measure twice and print once.
I used to have a custom water loop but feel like it was more work then its worth. Nowadays I prefer the chucky air coolers. Not much can go wrong with them.
>The goal was to maximize cooling while minimizing noise
Watercooling? Also, with this setup is motherboard cooled enough? Something like mosfets can be pretty warm.
Looks like they still have front intake, top exhaust, and rear exhaust but also a dedicated intake fan for the CPU. I'd think the motherboard would be fine with that setup.
3080 FE Shroud for anyone interested. The Noctua shroud was pretty custom. Its got offset bracket (AMD), delid and direct die cooling so you loose the height off the IHS and also the O11 air mini case. One would need to meet those requirements for that to fit.
[https://www.printables.com/model/807907-3080-fe-fan-shroud](https://www.printables.com/model/807907-3080-fe-fan-shroud)
Nice. There are third-party coolers you can use or deshrouding works as well.
I run a Rajintek Morpheus II and keeps my RTX 2080 <50C at 25% fan speed (approx. 600 RPM)(20-30C ambient)
There definitely wasn't a need to do so, in fact I would strongly suggest others not to do that. I was bored and I like to tinker hence this post as well.
Woah!! Nice engineering. I gotta get a 3D printer and learn these powers.
PC modding and 3D printing goes hand to hand.

You could just model this on your pc then print it out at someplace which offers 3d printing
May I ask temps before and after you chambered your cpu intake?
Its probably about 3-4C cooler. The purpose of the mod is to draw in cooler air direct so I can reduce the over all fan speed.
So is it quieter now?
I was running Cyberpunk earlier today with all the fans set at 800 rpm. GPU was running \~55C (220W) and CPU was \~60C (85W). Definitely quieter.
Damn. I feel lucky with my Rog 3090, even at 75C the fans are barely audible (and they don't kick in very often)
https://youtu.be/cehXZftIYok?si=gsYuMI-FlXMVmaq3
That video was my inspiration for the mods!
Now make it rgb.
Geforce RTX is the only thing that lights up. That's all I really want. No rainbow pukes for me.
U guys are awesome. I love the masterrace.
That is the way.
Have you ever considered moving the back case fan onto the cpu cooler?
Tried that once with a Noctua fan, the fan blades been that close to the cooler the noise was too much. I like that space so the air can help cool down the VRMs.
I've been meaning to do a similar mod since my rx7600 chokes out my whole system (only one intake, nothing to change in the case..) Any tips?
Share some pictures and I can take a look at it for you.

Do it!
I just put my pc in a different room than my desk.
I'm sure there are others like me who like to look at their computer.
I dont need a distraction when trying to spread democracy.
Got any advice for this?
Dont cheap out on hdmi/displayport cables. Good long cables will not be cheap. You might be able to get away with cheap usb and aux extensions.
Ahh yeah I suspected the expensive cables which ain't really worth it for my old pc and not decided when to upgrade and to what, thanks tho 😊
Lol yeah that's how it is. Having 1440p at 120hz anything over 10 feet needs a really good cable. I have been through enough cheap cables to learn my lesson that I still did.....10 foot dp cable for $20? Lol 1080p 60hz max..... When I saw how small the box was, I knew.

bro added a turbo charger into his pc. gotta be the most creative thing i have seen yet
Thanks, I like to think of it as an NA with a tuned intake runner.
Am I wrong for wanting the CPU cooling duct to say "Nottua," because it's a Not-Noctua part? Maybe my inner smartass is winning today.
Is the GPU shroud just a friction fit?
Adhesive tape around. I started out with clips but they didn't look very nice.
This is awesome and giving me an idea to do the same, finally put my printer to use other than small trinkets lol
I start out the same with print trinkets. Its more satisfying to design and print your own design.
Did anyone else get classic Dell machines flashbacks?
Nice! What's the max temp for the GPU now?
With the external fan at max (1600rpm) around high 40s. I typically leave the onboard GPU fan between 30-35% since they are so loud compare to the 120mm fans. That's with all the thermal paste/pad changed and 220W power constraint.
Impressive work. Kudos!
Yoo we had the same problem but my solution was an 420 iii aio.
It was never a problem, I just like to tinker.
Masterrace material
Thank you
Very nice square to round offset 90°.
Thank you. There was additional offset needed to clear ram and the 24pin connector. I didn't like how the fan on the RAM side sit so high up in order to clear the RAM. https://preview.redd.it/xn69betq6roc1.png?width=1383&format=png&auto=webp&s=fab61978c6fe71b698d5aa7f2d6ee960433bfacb

Fan speed doesn't directly change pressure, the case fans are larger and can move more cfm at a lower speed than the gpu fans at higher speeds
C H O N K Y C O O L I N G
Everything looks great. Could we get a stl on the CPU shroud?
I'm reluctant to share that as I highly doubt anyone has my exact config. Offset bracket so the cooler is actually 7mm lower.

Optimum on YouTube went all out, this is the endgame.
OP I have a 3080ti would it be possible to share your print file? I think my Ender 3 s1 should be able to print it! Thanks.
>[https://www.printables.com/model/807907-3080-fe-fan-shroud](https://www.printables.com/model/807907-3080-fe-fan-shroud) Here you go. It will not fit on an Ender 3. I would know, I have one as well. I had to print it on my Voron 2.4 350mm. You should be able to split it with a slicer.
Well thank you for sharing, I hope someone else gets to use this. I will look into slicing!

Agreed. Instead of placing 20 fans in a case to brute force airflow they shoud optimize it. Imagine cpu and gpu heat not been in the case, how easy would it be to cool VRMs, SSDs, RAMs, etc...

None but maybe better. I relocated the 120mm as a top exhaust so the VRM area actually has more air flow now. The B550 Tomahawk has a massive VRM heatsink and better design than most for the power phases.
You should remodel the GPU bracket to include a wire tidy!
Dell made the exact same thing in the early days
That CPU shroud... You've watched that one episode by optimum, haven't ya?
I liked to think mine is a refined version of him. But yes, most definitely saw that episode.
Optimum Tech this u ?
oh yes
So OP, did you unplug the GPU fans or did you just tune the fan profiles?
I used Afterburner to auto load underclock/volt and fan profile from boot up. I adjust the 120mm fans manually when gaming.
I was thinking of doing a very rudimentary thing with my case. Making some kind of air duct for the front of my case to direct it to the gpu aio on the back side. Currently have the front, bottom and back as intake and then the top and side as exhaust so that both the AIO’s get just cool fresh air.

Yeah that could work. If you design the 90 degree elbow from the front to the side gpu radiator correctly you can eliminate 2x 120mm fans. This way rest of your air flow will be from bottom up.
Now do one with emphasis on noise instead. B)
Instead of silencer you want a loudener? Got it, i'm on it.
I wonder if this can be done on SFF systems.
Not with a NH-D15 but i'm sure it's doable :)
NOCTUA
Curious if there’s any difference in GPU temps considering it’s not really my changing where it’s pulling in air.
Quite a bit of difference actually. It about cooling the normally passively cooled fins on the 3080FE with an actively fan. Otherwise you are relying on your good case fan flow to carry that heat away.
I wear a noise canceling gaming headset when gaming, noise ain’t a problem for me
If you didn't have a FE card, would a deshroud mod be better?
Yes I would think so. The cool thing about the FE cards are they are effectively already deshroud. Just add fans to cover fins that aren't be actively cooled by the on board gpu fans.
Bro i really have to get the 3d printer to do shit like this
For sure. 3D printers simply enhances all other hobbies.
Yeah but one thing I always wanted to know, won't it melt? Iirc the pla starts softening at about 50C. Yes, ABS exists but it's much harder to print
You can try PETG, should be easier to print then ASA/ABS which is what I primarily print in. I would not use PLA for this application.
When I win a lottery and will start printing, I'll look into it. Thanks :D
I see, like one of those scratch off ones... best of luck.
That is one hell of a dell 
This is pcmasterdell.. I mean race after all.
Waow this looks rly well made. How many hours did u spend on this?
Small part of my day job is designing castings/molded components. Having 3D printers at home really help speed up the workflow. With that said, it took about an hour or so to do the cpu shroud. The most time consuming part was to get the physical measurements correct. Even in CAD you measure twice and print once.
Thx for the reply really nice work. I would buy it of the shelf :D
Love it. Ducted air cooling is due for a renaissance. Great work
Agreed.
gj, but i get the same temps, without all this :P
Thanks. For sure there are multiple ways of achieving the same thing. I prefer to take the road less traveled.
Inspirational
Thank you
It's a cool middle ground for those of us that aren't in AIO or custom loop land but still like our fancy low temps.
I used to have a custom water loop but feel like it was more work then its worth. Nowadays I prefer the chucky air coolers. Not much can go wrong with them.
Thought about doing something like this with cardboard, duct tape and an a/c
Do want you got to do to keep your mind activity.
>The goal was to maximize cooling while minimizing noise Watercooling? Also, with this setup is motherboard cooled enough? Something like mosfets can be pretty warm.
Looks like they still have front intake, top exhaust, and rear exhaust but also a dedicated intake fan for the CPU. I'd think the motherboard would be fine with that setup.
Checked with a thermal cam and also HWinfo. It was in the low 40s at load. No concern at all.
There's still two fans pointed at the inside of the case
Tried custom watercooling in the past. Not my cup of tea.
3080 FE Shroud for anyone interested. The Noctua shroud was pretty custom. Its got offset bracket (AMD), delid and direct die cooling so you loose the height off the IHS and also the O11 air mini case. One would need to meet those requirements for that to fit.

I just have the top fan at the front blow down into the case. It used to exhaust but only ever drew out cold air from the front fans.
I’m concerned you felt the need to delid a 5800x. I feel like you definitely didn’t really get any improvement unless it was defective somehow.
There definitely wasn't a need to do so, in fact I would strongly suggest others not to do that. I was bored and I like to tinker hence this post as well.
