Air Flow for Air Cooled GPU Inside of Water Cooled 932

post #1 of 13
Thread Starter 
Hey, I was wondering how I could stop my 460 SE from getting suffocated by warm air from my rad.

I have a 932 with a triple rad mounted to the top. The rad fans are in push and drawing fresh air in from outside the case. So far, I have no real complaints about their performance for cooling my 4.5GHz 2500k @ 1.3v and my GTX 570 HD @ 800MHz. What I'm having a problem with is that I'm running a GTX 460 SE that's air cooled (because the PCB is non-reference) only for folding (and currently selling, if anyone's interested). It seems to suffocate on the warm air that's in the case. My fan setup is:

Intake:
Exhaust:
If I don't have all of the case fans on, the 460 warms up REALLY warm and has to spin its fan up to max speed, which is really loud. I originally had the side fan as an intake, but that seemed to increase my case temperatures pretty dramatically, so I swapped it around. I'm also planning on going push-pull on my rad with AP-14s, but I don't know if that will help or just make the problem worse.

TL;DR What would be the optimal airflow setup for the fans listed above?

Reversing the fans on the radiators to exhaust should help tremendously.

Intake:
Front 200mm
Side 200mm
Bottom 120mm
Back 120mm

Exhaust:
The 3x 120mms on the 360 rad

Hot air goes up right? Switch the rad fans pulling out of the case and everything else in.
Sorry post at the same time you did

Won't that decrease the effectiveness of the rad though? The air inside of the case should be warmer. I guess the question is is it enough to matter?

1 or 2 degrees higher, no biggie. Mount your rad externally if you want the best of both worlds.

Well if you move alot of air into the case it should not be that hot for the rad. Or you can water cool the video card too and add a 120.1 rad

the air in the case won't be that much warmer...you've got all the heat from the GPU/CPU running through your loop right? So the only heat being generated inside the case is from the PSU, which is already exhausting itself out the back, and the 460 which is also exhausting out the back. I think you would get much better performance having the radiator blowing the heat up and out, instead of trying to draw air in...

Or you could try

Intake:

1 200mm CM Megaflow (front)
3 120mm Yate Loon D12SH (top, pushing down onto rad)
1 120mm CM Sickleflow (bottom)
1 200mm CM Megaflow (side) - If its still warm try turning this off.

Exhaust:

1 140mm CM LED Case Fan Where is this located? If its the Back its Exhaust

Shouldn't need an extra rad for the 460. Its clocked all the way down. The problem with this card is that its not a reference PCB, so I can't find a block for it.

I'll try out your suggestions when I get home from work tonight.
