fan configuration AIO Push or Pull air? Intake or exhaust?

[TheNuzziNuzz]

I have attached an image of my build. Using all Arctic P12 fans.

 

I just installed an arctic freezer AIO. I decided to put it on the right side for RGB effect, acting as exhaust. The top of the case is filled with p12s also acting as exhaust. However, I found that since adding the AIO, where there used to be air hot by feel coming out of the top of the case, it seems the AIO fans are sucking all of that warm GPU air into the radiator...the opposite of what I expected.

 

My question is, should I flip the direction of the fans on the right? OR Switch the AIO to the top of the case as exhaust, and use the three p12s on the right as intakes/exhaust? If so, I think the p12s on the right as exhaust would suck up the hot air as right now the top feels almost cool, which would certainly lower my CPU temps compared to now. However, I think using p12s as intake could also give the GPUs more cool air, but leave more heat for the AIO on top.

 

I really hope that made sense! Thanks for your thoughts!

 

 

IMPORTANT NOTES

1. I know this is the worst possible case for this, I got it for free - I'm already looking for new options please don't make comments about it.

2. I do use both 3090s 100% utilization as I do 3D animation. It's not a stupid purchase, it's my job. I camped out for 12 hours @ bestbuy to get them for MSRP.

3. GPUs currently run at ~54 (bottom) & ~63 (top) degrees (with fans manually at 50%)

4. CPU (5800x) runs ~97 deg (40c idle)....too hot, but less hot than when I was using a hyper 212 evo...that was very bad

Is this a 011 dynamic?

 

What fans are you using on that arctic liquid freezer II? If they aren't made for pressure then they will suck quite badly at cooling a aio.

 

The fans should have been intake on the aio not exhaust. It's really heating up the aio as well you got 2 heat monsters pushing air into it.

 

The tubing of the freezer seems a bit stressed it might have kinked and is preventing flow. So you might wanna see what happens when you just lay it on top of the case temporarily.

personally I'd move the rad and rgb fans to the top as exhaust. making side and bottom intake

[Hairless Monkey Boy]

For the best CPU temps, do intake. For the best GPU temps, do exhaust. Based on your current temps, I'd do intake.

 

In either case, do Pull. There is no performance difference with Pull or Push, but Pull is easier to clean.

 

So all you would need to do is turn the fans on the radiator around.

All fans are Arctic p12s.

 

What looks kinked?

Thanks! Strangely, it seems having the side as exhaust actually collects most of the heat from the GPUs leaving the top exhaust doing almost nothing.

I don't think I follow. I don't want to do an intake on the top because heat rises. Are you suggesting I flip the fans on the right & keep the rad where it is?

Nor would I, though heat rising has little to do with it.

Yup.

Heat rises but in pc cases with fans it does not matter.. the only problem i see with ur build is 3 intake and 7(!!) exhaust fans. 

you kinda want more intake fans or the same nr of intake as exhuast. 

i would do top and buttom intake

if ur saying im wrong  with all the data out there telling you that push is 1-3c better than pull...  

btw i did a push vs pull on a QL120  6c diffrence

This is frankly pretty much the same as asking which thermal paste is better. They all pretty much perform within margin of error of each other, and other factors come into play anyways that can skew results.

 

If you care that much, try the different orientations yourself under various kinds of loads and compare the results. Then go with whichever performs best for your particular rig. Otherwise, if you don't feel like going through all that work, just stick with how you have it now. It's probably fine as is.

I might be crazy here but I think you have too many fans. There's no place for the air to go efficiently.

Move the rad to the top as exhaust with P12's. You can flip the RGB fans at the side for intake.

I had mentioned this earlier and still agree. although rgb fans are p12s too. personally think the rgb fans would look better at the top as performance would be the same.

rip sli...

 

the way i see it the aio only get 1 fan of fresh air flow  and the gpu exhaust in to the aio... i would put the aio and intake. or you can put the aio on top and have bottem top intake and side back exhaust. dont no witch will be cooler thow. the intake from the top should help the vrm temps

 

as for sli temps nothing you can really do. only water cool them.

Hmm, appreciate the perspective. I was thinking the exact oposite.

just turn the top fans to intake and ur fine   and its the easiest

Hi everyone, I found the optimal solution:

 

1. Rad on top, fans pulling, exhaust

2. Bottom intake

3. Side Exhaust

4. Rear intake! Sounds strange, but this gives the rad cold air.

 

The side exhaust now without resistance from the rad sucks the GPU air out so well I'm actually experiencing a ~15 degree drop in GPU temperatures all around...honestly very surprised. At idle right now the GPUs are ~33 and ~39. Ambient is about ~22. This is with the default fan curve, meaning the lower cooler card's fan isn't spinning at all while the top as at it's lowest (30%).

i would rotate the back fan to hide the catchup and muster cable other then that looks good. you can also ramp the gpu fans up too a point were you cant hear it and set that as the idel temp will keep things cooler at idle. i have my gtx 1080 set at 25% at idel as at zero it would pulse from 49 ramp up then gos down to 48 stops ramp and repeats...

1. Yeah I guess i'm short a p12 so I'm just going to buy another one and that will take care of that mustard. Have them rotated as to wrap the wire around so I have less excess elsewear.

 

2. That's a pretty cool idea, although I wouldn't want some kind of fan-speed software running in the background all the time.

thats the 100% worst for temps but ok

No, based on my testing this is the coldest the systems run.

Tell me about ur testing
3 intake and 7 exhaust + top rad + pull on top rad = Worst + worst + worst  ( and ur saying = best )   interesting
