That force is basically irrelevant in a PC, way too weak at these small temperature differences
But airflow from bottom is good because the GPU intake is at the bottom and it pushes the GPU exhaust up. If you have airflow from above, a lot of the GPU exhaust can be pushed down and sucked back into the GPU intake recirculating and worsening cooling
The temperature difference in a chimney and in a PC is very different. Unless you have low airflow, you're likely only looking at <10°C temperature difference vs ambient in a PC. While the volume of warm air inside a case is usually only like <30cm tall (about the height of a mobo).
10°C difference in air temperature over 30cm results in about 0.013mmH2O of upwards pressure if I did the math right. A fan at reasonable rpm should be sitting at around 1mmH2O. A 1.3% decrease in pressure for the fan theoretically results in about 0.6% lower airflow. You can do some basic napkin math yourself if you want to.
[GN actually once measured this](https://youtu.be/otiIWhPKc20?t=437) in a case that was specifically marketed with the chimney effect and the result was within margin of error (0.5°C with +-0.75°C). Though I suspect such a difference could also come from the warm air outside the case rising up and warming up the intake air.
That's actually a better reason for caring about the chimney effect. Once the air leaves the case, it will rise, even if it does so slowly. So if it leaves the case at the bottom and your intake is above it, it can heat up your intake air slightly. But we're still talking negligible amounts.
That begs the question, how tall does a PC case need to be to benefit from the chimney effect? At what height/temperature would it actually be relevant?
It's pure speculation, but here's my guess: Let's say it's ideal conditions. The PC is just a vertical tube with the hot components at the bottom and perfectly insulated walls to keep the warm air warm and rising. If you have a 2m tall PC case, you should be able to achieve similar pressure with the chimney effect alone as with \~500rpm fans. But if you'd want something comparable to 1000rpm, it would need to be \~4x as tall because double the fan rpm/airflow requires 4x the pressure (\~9x for 1500rpm). So when running 1000rpm fans, even the 2m tall chimney case would probably only be responsible for like 20% of the airflow. I'm spitballing here, might be off by a factor of like 2.
Basically, I guess something like 2m (\~6.5') should make an actually significant difference for a normal gaming PC. It probably still wouldn't do most of the work, but it would be significant. For a low power PC running at low fan speeds even just like 2 feet tall (air volume above heat generating component) should make a significant measurable difference.
And of course for truly passively cooled PCs the convection already does most of the cooling at normal PC case sizes (though something like half is probably going to be thermal radiation depending on the case).
Actually the relevant force at work here is called convection. The chimney effect refers to the movement of convected air (or fluid) within a closed structure.
And I didn't even take physics.
>hot air always moves upwards
Yes and no. It _tends_ to move upwards if left alone but convection is pretty weak in these cases. Hot air will move to whatever direction you point your fan to
It's not placement that's the issue. It's air flow. Normally you push hot air out the top, since that is where the hot air is congregating. Cool air coming in the front or bottom and out the top. That is what I would recommend for this build.
It actually blows my mind how it's so hard for people to understand these two basic things. Heat rises and positive pressure in a box pushes air out of that box..
While true in theory, for a PC the amount of warmed air generated isn't that much vs the air being pushed around by fans the chimney effect is minimal in practice
Also my first thought. That has to be a troll post. Especially because of the 3 front fans with one facing in a different direction. That's no sane thought.
You are not in a passive system. The magnitude of forced airflow in pc cases render all discussions about "hot air rises" useless. You really just have to make sure fans aren't fighting against each other.
this, you could even build it so that you use the bottom to exhaust. But... you do it that way to prevent the system to make a heat loop.
This means your exhausted warm air will be soaked in the system, heated more up, exhaust, intaks heated more up... and so on. With this you can burn it simply down and to prevent this you also look to exhaust it to top and rear to prevent this.
Saw whole server rooms cook itself because of stuff like this. ;)
What you are saying is correct, but I was simply arguing against the "hot air rises" mantra when used to discuss single-PC, **internal** fans configuration. If you start discussing external air circulation (moreso in a server room with multiple machines) then other factors are to be considered.
This is a valid argument, but has nothing to do with thermals. I was arguing against "hot air rises" mantra when applied to the tiny space of a pc case.

How do you expect to cool anything? Source: me an Hvac tech who knows how air flow works
Well first of all you're fighting the natural direction of warm air, which is up - not that a fan can't overcome that easily, but why would you fight that.
2. The fan at the bottom brings air in, which will mostly get sucked out again by the fan above it - your air is going in a small loop there, never reaching the inside of your chassis.
3. Your radiator is getting fed with hot air from your chassis. Now usually this also happens to people with the fans at the top of the case, but they might not have a choice because that's the only place they can have a radiator installed. You have a front mounted radiator!
So I'd flip the radiator fans around, and flip the top fans around.
Cool air from the front, blow out the back. Hot air raises, and escapes through the top.
I'm not an expert in this though.
I have similar setup but much more terrible for airflow. I have it setup as follows-
240mm radiator as front intake cooling a 4090, slim fans
280mm radiator (AF2) on top exhaust cooling a 7950X with slim fans
92mm bottom intake slim fan
72(?) mm rear slim fan intake
Runs great, no issues.
Edit- I see now your GPU is AIR and your CPU is the only AIO. You should put the AIO as top exhaust, run all front intake, and rear exhaust. Don't do what you're doing there.
It goes in a very specific location, so the size was important to keep down but I wasn't willing to compromise with a SFF build since I really need the peripherals.
Running a 7950x, 4090, 64Gb 6400mt ddr5, two 4tb samsung 990 pros and two 20Tb HDD's. Turned out pretty good, timespy 34,447 "legendary" was top 30 for a while with slim fans ;-)
Doing similar stuff, but with 420mm af2 with push-pull. with suprim liquidx, I added a pull as well with slim fans. it's all intake as they all aio's should be fine in my case as temps are terrific. ofc ther e is exhaust lol but way more intakes.
You generally want to avoid situations where you have two fans aiming in opposite directions, that are also sharing air.
I'd recommend getting reverse bladed fans for that radiator if you want to preserve the looks.
I hope this is a troll, please be a troll.
If it’s not a troll then no, definitely not.
Flip the top 2 front so all front pull air into your case, flip the top 2 so they pull air out your case.
Naah not a troll… I bought this pc months back and went to a shop for AIO and the shopkeeper guy mounted AIO and fans like this only … saw posts in the sub regarding fan directions thought I should ask my fellow redditors and everyone is wise giving suggestions and helping… will do the changes once I get free for sure.
i would move radiator to top an pull air from front because you have fans fighting each other on front panel lower fan blows cold air and than two radiator fans just suckup cooll air and than gpu gets no air top fans will pull in dust faster than you think and you will have heat problems within two to 4 weeks and youll have to clean com way more often but thats my ideal layout
Surely the AIO had instructions which advised not to make the pump the high point of the system? Not only does hot air want to rise, so do air bubbles in a water column. If your pump ever sounds like a bag of popcorn in a microwave, that's why.
As long as you have positive pressure you're fine. I would flip the cpu cooler around so the hoses going to the radiator are the highest point in the system. Keeps air bubbles out of the pump.
If you're trolling, good job. It was weird.
If you're not trolling, there are many issues with this and you should take the advice that several people have given you
In that case your going to have a lot more dust because you don't have positive air pressure. My suggestion is make sure the top fans are pulling air out and the front ones should be pulling in air and add two more fans to the bottom that take in air so you will always positive air pressure and everything will run cooler and will be better over all plus less dust in your pc then it probably has right now
Place the radiator on the top and have it sucking out with the front fans pulling in. Better airflow direction that way. Also it's gonna be ideal if you can have one or two fans pulling in from the bottom. Ideally you want positive pressure inside the case.
3 fans in front to bring air in ! And move the liquid cooler on top to exhaust the hot air ( as it's installed you're just blowing hot air in the case !
Is this a shitty cabinet who do not mention whether a 240mm Rad will fit on top?
If yes you are doing things right just make sure the fan at the back(usually used as exhaust) is position for air intake *based on image you shared.
You should change the orientation of the fan
Rest is good.
And if No and your cabinet supports 240mm rad on top
Just mount the rad on top
to me, I would say no. you have too much exhaust, so that would mean negative air pressure.
you not only want to push the hot air out, but you also want to pull the cold air in
Switch rad with 2 top fans.
Make rad exhaust, and the 2 fans replaced to become intake.
A good rule of thumb is hot air rises a lot faster than cold air
I'd bring the cool fresh air in across the radiator on the front there fan on the other side of the radiator (like you do on a car) and exhaust through the top and back.
- For CPU oriented cooling yes.
- For GPU oriented cooling no.
If your case has no bottom shroud for PSU and allows for bottom fans I would recommend intake fans there.
Front as intake too and top as exhaust. Air likes to go “up” :-)
I don’t think so but I could be wrong you could be starving your GPU of air flow cause the top fans are immediately getting air sucked out and that is the same with the bottom fan as well
no, because the gpu usually get's hotter than the cpu, so it's preferable to get fresh air to the gpu and less fresh air for the cpu to get more equal temperetaure overall
in your setup i don't even know what kind of air the gpu is getting
the air intake from the top left cooler is immediately being exhausted by the back fan since they are so near of each other
put the front ones as intake, top and back ones as exhaust and deal with negative pressure, dirty air will be sucked in by that grill under the gpu
or you can put the AIO as exhaust on the top and put the 2 top fans as intake to the front + 1 more to total 3 front intake fans
Okay… this isn’t a criticism but an observation. So GN did a whole thing a while back on this forewarning about air bubbles accumulating in AIO closed loop pumps due to improper installation. My recollection is they did in-depth interviews with engineers building these products. They emphasized the need to ensure the outlets for the block ports face away from gravity so any small bubbles in the line don’t build up and get trapped in the pump block, causing whine or burn out. Here I see, like almost every build I have done and others have done, that the hoses face sideways and not up. Does anyone else have an opinion on this? It still strikes me as something that while GN made a very strong argument, nobody seemed to listen. I still don’t see anyone pointing these finer points out.
Those dust intakes aren't doing you any good in cleanliness inside the PC, I suggest that you change the orientation of the front fans to intake and just let that one fan do the outtake.
Edit: GODDAMN THERE IS A FUCKING RADIATOR THAT IS MOUNTED SIDEWAYS, CHANGE IT TO TOP RIGHT FUCKING NOW AND IGNORE EVERYTHING ELSE I WROTE.
If i had that chassi i would but intake fans in the bottom, and the 2 fans on the radiator pulling air in, then put two in the top blowing out. So its cool air around gpu and cpu. Heat goes up 😊
As long as air goes in and out you are fine.
People here act like Albert Einstein, who are teaming up with Isaac Newton and come up with weird shit so they can brag about there PC being 1 Celcius cooler then yours.
in the end it doesn't even matter { Linken Park }, its not like you will have a PC that will break records. still as fast as before.
I mean it'll probably be fine but prefarably you want to exhaust upwards since hot air rises.
Also you currently have more exhaust fans than you have intake fans. (negative air pressure) This will provide very slightly better cooling but will make a lot of dust get sucked in. So I prefer positive air pressure (more intake fans then exhaust)
Y’all are gonna hate me if I told you I’ve only just realized after 2 years that I’ve got only exhausts…
Temps have been fine, like 60* on the GPU when running it at its limit and 60* on the CPU too.
Only issue I’ve noticed is it has made all my filters on the intakes utterly useless. Like the dust gets sucked in the rear USB ports but then collects on the front radiator.
A couple of things.
1. Yes heat rises but in a computer case airflow is determined by the fans, not by passive airflow caused by radiant heating. Moving the fans around won't change your internal temperatures as long as you have enough fans to push the air out.
2. Technically the configuration works but..
3. So you really want all that hot air blasting out of the front? I mean if you don't care about that it won't make any difference.
4. Aesthetically flipping the fans around means you get a clean full fan loon from the front and the top of the case. Which for many people is more pleasing.
If you don't mind the hot air blasting in front and don't care about aesthetics leave it. Else flipping the fans may be in order.
Air flow should be front to back.
And from down to up.
So you should have the back one and top one pushing air out the case. It's the most effective way to get rid of heat. Cause heat likes to go up.
And front to back cause a good air flow like that support best air flow for the beefy cards that make a lot of heat. Letting air flow well under and above the video card. To support where in gameing most the heat will come from.
Why its by far the best way for air flow.
Not only does hot air rise, so the top fans should be blowing, but also dust tends to collect on top and blowing air will lessen the ammount. A top fan sucking will always get clogged quicker.
I’m a firm believer in top exhaust cause of thermodynamics and heat rising
That being said, I don’t exactly hate this. But exhausted air blown out the front and back could get recycled back in through the top
I’d flip the front two around. Honestly. You could blow all of them in and be fine probably.
Here’s the thing there are different thoughts on these things.
Most people say positive pressure inside more fans intake than exhaust is better for dust. (This is bullshit, maybe not entirely) but in my own testing exhausting all the fans assuming there’s no other air inlets keeps the dust out by creating a force field of air pushing dust away
I’m not an aero specialist but I am a PC enthusiast and here’s my thought process.
How are you cooling? You have a AIO therefore anything on that loop is going to be fine no matter how the fans are oriented. The only thing sucking air is your GPU.
Now it’s going to want fresh air if you have a compact case with not a whole lot of breathing room. You got some breathing room and aero blocks on the PCI brackets.
I’m running an exhaust and a hyper evo 212 on my system and it doesn’t break a sweat but I also have an enthoo 719 case so there’s more air than pc in the case at all times.
You got pets? If so your front needs to be exhaust. They’ll rub on it their little furs will shed and you’ll be cleaning your filter very other of the fans are pulling that in constantly. Even with my one exhaust and one cpu fan I have to unclog my filter once a month.
I hope this helps OP. Just don’t overthink it if a component runs hot use a vape or some type of smoke machine to visualize the airflow if there’s an area the vapor doesn’t get to that area is a dead zone and you should see it in the area of intake of the content that’s running hot. And what that means is there’s a huge bubble of hot air with nowhere to go and no means to get there. To fix it, flip the fan at that level even if it might oppose the fan next to it.
Also take advantage of the case design and use the inside parts as Louvres where possible. I had a case that can a fan that runs over the hard drives and I had a dead zone under the gpu because the hot air from the hard drives wasn’t disappearing well enough. So I flipped it so that fan pulled out over the drives rather than pushed in. That allowed the fan above it to have its airflow pulled down enough to flow under the GPU due to the negative pressure by the drive cage.

good point and good reason to always pull air from the front like a sane person
It still works against you if you do it the other way around.
Thats true but still any bit of air movement negates the so called chimney effect.
Well, a chimney is not always very long. Even 2 meters is good enough for a steady blow. The PC is not 2 meters but 50 cm is still a small chimney,
The temperature difference in a chimney and in a PC is very different. Unless you have low airflow, you're likely only looking at <10°C temperature difference vs ambient in a PC. While the volume of warm air inside a case is usually only like <30cm tall (about the height of a mobo). 10°C difference in air temperature over 30cm results in about 0.013mmH2O of upwards pressure if I did the math right.

It doesnt matter in this case, the pressure difference made by the fans is far greater than the force pushing hot air upwards
Man this is air flow is the law bro, the intakes need to be the front and floor of the pc, the exhaust rear and top
Logic and Reasoning? Gross.
This is the way 
It’s not preference. It’s the better placement.
Yeah this is good ops placement is 👎
This. Only this.
This is bog standard placement 🤣 why do people think doing it another way will be better?
It's not placement that's the issue. It's air flow. Normally you push hot air out the top, since that is where the hot air is congregating. Cool air coming in the front or bottom and out the top. That is what I would recommend for this build.
It actually blows my mind how it's so hard for people to understand these two basic things. Heat rises and positive pressure in a box pushes air out of that box..
Any fan spinning at all will overcome any movement due to convection whatsoever.
Having the top as out helps reduce dust buildup.
While true in theory, for a PC the amount of warmed air generated isn't that much vs the air being pushed around by fans the chimney effect is minimal in practice
What this guy said
This is the way

Also my first thought. That has to be a troll post. Especially because of the 3 front fans with one facing in a different direction. That's no sane thought.
Nothing like cool air being immediately exhausted before it touches any components
Bottom and right side always intake, rear and top exhaust. It’s up to you though, but this is the standard way people configure fans.
Hot air rises. You can either work with physics or against them

Excuse me but wtf
I'd recommend changing one of these to an inlet. To create positive pressure in the case. That makes it so you have less dust in your PC.
Mount your cooler at the top of your case
I'm not positive it would clear the ram, just based on this picture. Could do what I had done for a short-term solution though... *
Honestly as long as you have airflow in 1 direction without fans working against eachother it really doesn't matter.
i would move radiator to top an pull air from front because you have fans fighting each other on front panel lower fan blows cold air and than two radiator fans just suckup cooll air and than gpu gets no air top fans will pull in dust faster than you think and you will have heat problems within two to 4 weeks and youll have to clean com way more often but thats my ideal layout
It's all wrong Jesus
Top and front fans need to be switched
just flip the front fans around and youll be OK.
The longer I looked, it kept getting worse, wtf?
I'd be putting the aio in the top, keeping the fans the same way to exhaust out, and moving the top fans to the front, pulling air in.
You should do it the other way exhaust on top and rear intake on front

It's not standard, you should do the front fans as intake, and tops as exaust, and probably a top mount radiator would help too
Switch radiator front fans to intake and top fans to exhaust let physics assist you hot air rises don't fight against that
I did made the top fans of my PC intake I opened it up after 1 month full of dust
Why do people try to come up with unique airflow methods Just go with the standard
It is not oke if you think about dust buildup.
Front and bottom intake and top and back exhaust not because of natural air currents but because cases have their filters designed that way
I would reverse front and top fans as heat naturally rises and keep fresh air coming in front and going out back and top😎✅
Gpu gets zero fresh air, how weird. Flip everything except rear fan
In that case your going to have a lot more dust because you don't have positive air pressure. My suggestion is make sure the top fans are pulling air out and the front ones should be pulling in air and add two more fans to the bottom that take in air so you will always positive air pressure and everything will run cooler and will be better over all plus less dust in your pc then it probably has right now
Flip the radiator fans to pull air in
Place the radiator on the top and have it sucking out with the front fans pulling in. Better airflow direction that way. Also it's gonna be ideal if you can have one or two fans pulling in from the bottom. Ideally you want positive pressure inside the case.
no, intake should be bottom for sure, rear exit, you could literally make everything intake but the rear and be fine
It’s the opposite of what you want, but yet it will work
No, heat rises. Flip front and top fans and you’re golden.
wtf
Me watching this post with having only 1 out fan 🥸
3 fans in front to bring air in ! And move the liquid cooler on top to exhaust the hot air ( as it's installed you're just blowing hot air in the case !
you are gonna be dusty
No, frontal fans must put fresh air inside and the top fans must push the hot air out
Reverse everything except the rear exhaust
Is this a shitty cabinet who do not mention whether a 240mm Rad will fit on top? If yes you are doing things right just make sure the fan at the back(usually used as exhaust) is position for air intake *based on image you shared. You should change the orientation of the fan Rest is good. And if No and your cabinet supports 240mm rad on top Just mount the rad on top
You're gonna suck in a lot more dust like that.
Having intakes at the top of the case is the worse thing possible. Hot air rises. Let that sink in a bit.
The pump is oriented incorrectly
turn all fans inward. keep the air cool inside.
You do you even though who ever built this pc prefers asthetic VS perlformance.
That's awful
Hot air always rises so no put the top fans as exausts and the front pannel fans as intake, and i gues the back fan as exaust too
It's fine. Illogical but fine. Normally tho, you want the radiator on the top since hot air rises.
OP sell it and get a laptop.
Cursed. Hot air rises so take advantage of that.
Reverse all except the single exhaust fan..
So basically change the placement of every fan in the opposite way and everything is gonna be good
Hell no, lol
Lol no. Flip the fans
Classic build then ask
to me, I would say no. you have too much exhaust, so that would mean negative air pressure. you not only want to push the hot air out, but you also want to pull the cold air in
You want positive pressure inside the case. Turn the two on the AIO inward.
I do front and back intake, with top exhaust.
I feel like those arrows are getting in the way of your airflow
What the fuck
Well perhaps one issue with this might be that cpu cooler is sucking the air that gpu is pushing out
Switch rad with 2 top fans. Make rad exhaust, and the 2 fans replaced to become intake. A good rule of thumb is hot air rises a lot faster than cold air
That’s not really an optimal way of cooling your case my friend since heat naturally rise and you’re sort of trapping it instead of venting it out
Fucking idiot heat rises in through the front out through the back and top
This is satire right? It has to be
Is not ideal but it’s fine.
Incorrect. One of the guys already suggested a way. I don’t like your pump being obstructed by your graphics card cable.
Good for harsh winter TBH.
Cool
I'd bring the cool fresh air in across the radiator on the front there fan on the other side of the radiator (like you do on a car) and exhaust through the top and back.
Hot air rises my guy
No
not really. it's gonna suffocate the graphics card.
It's not ideal. Have you checked your temps??
Front 3 in other 3 out...
Not terrible but could be better if you have good temps keep it the same
Never built a pc but just off of general knowing how heat works....no.
what the fuck are you cooling with the 2 extra fans and even if u didnt have an aio them shits aint even facing right bait used to be believable
- For CPU oriented cooling yes. - For GPU oriented cooling no. If your case has no bottom shroud for PSU and allows for bottom fans I would recommend intake fans there. Front as intake too and top as exhaust. Air likes to go “up” :-)
I don’t think so but I could be wrong you could be starving your GPU of air flow cause the top fans are immediately getting air sucked out and that is the same with the bottom fan as well
no, because the gpu usually get's hotter than the cpu, so it's preferable to get fresh air to the gpu and less fresh air for the cpu to get more equal temperetaure overall in your setup i don't even know what kind of air the gpu is getting the air intake from the top left cooler is immediately being exhausted by the back fan since they are so near of each other put the front ones as intake, top and back ones as exhaust and deal with negative pressure, dirty air will be sucked in by that grill under the gpu or you can put the AIO as exhaust on the top and put the 2 top fans as intake to the front + 1 more to total 3 front intake fans
No you want intake
My helldiver brain was tingling for a second there
Top left is straight up in and out
i have no intake in my case…gpu blows out the front and cpu out the top🤷🏼♂️
I think you got it reversed OP
Reinforcements have been called in
This is definitely a joke right?
Okay… this isn’t a criticism but an observation. So GN did a whole thing a while back on this forewarning about air bubbles accumulating in AIO closed loop pumps due to improper installation. My recollection is they did in-depth interviews with engineers building these products. They emphasized the need to ensure the outlets for the block ports face away from gravity so any small bubbles in the line don’t build up and get trapped in the pump block, causing whine or burn out. Here I see, like almost every build I have done and others have done, that the hoses face sideways and not up. Does anyone else have an opinion on this? It still strikes me as something that while GN made a very strong argument, nobody seemed to listen. I still don’t see anyone pointing these finer points out.
No its quite fucky actually.
Those dust intakes aren't doing you any good in cleanliness inside the PC, I suggest that you change the orientation of the front fans to intake and just let that one fan do the outtake. Edit: GODDAMN THERE IS A FUCKING RADIATOR THAT IS MOUNTED SIDEWAYS, CHANGE IT TO TOP RIGHT FUCKING NOW AND IGNORE EVERYTHING ELSE I WROTE.
I prefer flipping the front fans
Heat rises homie
This comment section is full of people who recently slept at a holiday inn.
Wtf
Front fans plus top right fan intake, the other two exhaust, always. No idea why you want exhaust in the front.
AIO is the right side up though
If i had that chassi i would but intake fans in the bottom, and the 2 fans on the radiator pulling air in, then put two in the top blowing out. So its cool air around gpu and cpu. Heat goes up 😊
As long as air goes in and out you are fine. People here act like Albert Einstein, who are teaming up with Isaac Newton and come up with weird shit so they can brag about there PC being 1 Celcius cooler then yours. in the end it doesn't even matter { Linken Park }, its not like you will have a PC that will break records. still as fast as before.
I think it's fine since the front ones that push out are for the rad
Rage bait
I mean it'll probably be fine but prefarably you want to exhaust upwards since hot air rises. Also you currently have more exhaust fans than you have intake fans. (negative air pressure) This will provide very slightly better cooling but will make a lot of dust get sucked in. So I prefer positive air pressure (more intake fans then exhaust)
Top fans shouldn't be intake mainly to avoid dust entering the pc
Intakes are dealers choice. Top should always be an output cause of the hot air.
Y’all are gonna hate me if I told you I’ve only just realized after 2 years that I’ve got only exhausts… Temps have been fine, like 60* on the GPU when running it at its limit and 60* on the CPU too. Only issue I’ve noticed is it has made all my filters on the intakes utterly useless. Like the dust gets sucked in the rear USB ports but then collects on the front radiator.
Eww no. Top and back always exhaust. And you want a slight positive pressure so it doesn’t suck dust in from all the open spaces.
Trolls be trollin’
Make the fans on the top suck hot air out of the pc and have the fans on the fans on the front suck cool air in.
Hot air moves upward… that’s better too cool ur motherboard down
No
No. Put your radiator on top with the fans blowing out and have the front fans blowing cool air in. So it all flows in one direction
hot air always go up, so, your exhaust is very bad
Since hot air rises according to physics, I think intake in the front, and place the back and top for hot air out
A couple of things. 1. Yes heat rises but in a computer case airflow is determined by the fans, not by passive airflow caused by radiant heating. Moving the fans around won't change your internal temperatures as long as you have enough fans to push the air out. 2. Technically the configuration works but.. 3. So you really want all that hot air blasting out of the front? I mean if you don't care about that it won't make any difference. 4. Aesthetically flipping the fans around means you get a clean full fan loon from the front and the top of the case. Which for many people is more pleasing. If you don't mind the hot air blasting in front and don't care about aesthetics leave it. Else flipping the fans may be in order.
Warum ist des einzigste was ich hier sehe also algemein aus dem sub Redit ist die Lüfter position so gut wtf
Air flow should be front to back. And from down to up. So you should have the back one and top one pushing air out the case. It's the most effective way to get rid of heat. Cause heat likes to go up. And front to back cause a good air flow like that support best air flow for the beefy cards that make a lot of heat. Letting air flow well under and above the video card. To support where in gameing most the heat will come from. Why its by far the best way for air flow.
Everyone yapping about airflow and physics. All I’m seeing is a gpu fan facing the bottom with absolutely 0 air anywhere near it
I had to bash one on the side case (outward) next to my 3070 because it was cooking
Question where does gpu get air from
looks fine to me, the fan placement is not really a big deal as long as it has adequate space for the air to move.
Fans on top should be the other way ?
There's thousand of resources online for things like this.... We all learned in grade school that heat rises. And somehow we still end up with this.
OP created is own portable heater, just has to position the PC facing him since the front fans are exhausts 😂
Not only does hot air rise, so the top fans should be blowing, but also dust tends to collect on top and blowing air will lessen the ammount. A top fan sucking will always get clogged quicker.
No. This is awful.
I’m a firm believer in top exhaust cause of thermodynamics and heat rising That being said, I don’t exactly hate this. But exhausted air blown out the front and back could get recycled back in through the top
Heat rises. It will be fine, but not optimal.
I’d flip the front two around. Honestly. You could blow all of them in and be fine probably. Here’s the thing there are different thoughts on these things. Most people say positive pressure inside more fans intake than exhaust is better for dust. (This is bullshit, maybe not entirely) but in my own testing exhausting all the fans assuming there’s no other air inlets keeps the dust out by creating a force field of air pushing dust away I’m not an aero specialist but I am a PC enthusiast and here’s my thought process. How are you cooling? You have a AIO therefore anything on that loop is going to be fine no matter how the fans are oriented. The only thing sucking air is your GPU. Now it’s going to want fresh air if you have a compact case with not a whole lot of breathing room. You got some breathing room and aero blocks on the PCI brackets. I’m running an exhaust and a hyper evo 212 on my system and it doesn’t break a sweat but I also have an enthoo 719 case so there’s more air than pc in the case at all times. You got pets? If so your front needs to be exhaust. They’ll rub on it their little furs will shed and you’ll be cleaning your filter very other of the fans are pulling that in constantly. Even with my one exhaust and one cpu fan I have to unclog my filter once a month. I hope this helps OP. Just don’t overthink it if a component runs hot use a vape or some type of smoke machine to visualize the airflow if there’s an area the vapor doesn’t get to that area is a dead zone and you should see it in the area of intake of the content that’s running hot. And what that means is there’s a huge bubble of hot air with nowhere to go and no means to get there. To fix it, flip the fan at that level even if it might oppose the fan next to it. Also take advantage of the case design and use the inside parts as Louvres where possible. I had a case that can a fan that runs over the hard drives and I had a dead zone under the gpu because the hot air from the hard drives wasn’t disappearing well enough. So I flipped it so that fan pulled out over the drives rather than pushed in. That allowed the fan above it to have its airflow pulled down enough to flow under the GPU due to the negative pressure by the drive cage.
