Hey guys, I need a final bit of help with my case.

9609531469.gif


Here's my current setup, WC exhausting, 120mm intake in the front. I have a sidepanel fan and I'm not sure where I should put it, either position 1 or 2, intake or exhaust? Not sure if I should use it to exhaust the PSU and heat around the 7900GT or use it to intake and cool the 7900GT more and maybe possibly blow some cooler air on the northbridge (which is the Asus fanless design) A8N-SLI Premium.

Thanks in advance!
 
Are you sure your diagram is correct? Video cards sucks in air IIRC and so does PSU's from the inside to the outside.
 
Is the red "watercooling" box the radiator? Is your gfx card water cooled? (it doesn't look like it) Is your PSU really an intake? Do you have a photograph of the system?
 
Yes, the red cooling box is the rad. I have a Seasonic S-12 500w PSU, I just put my hand behind the unit and there's no air coming out the back, so I'm assuming the fan is exhausting into my case.

Not sure about the video card, the cooler I just purchased for it (AOC Evercool Turbo 2 Dual Heatpipe VGA Cooler) I think has a fan blwoing onto the heatpipes, so lets assume that it'll be doing that when I receive it.

No pics of my rig, but the only thing cooled right now by WC is the processor.
 
If the PSU was blowing into the case, you would still feel the airflow instead of nothing. It is because that PSU is efficient enough it doesn't have to move very much air. I would assume that it exhausts air like the seasonic PSUs I have used.

Voting for placing your intake fan at location #2 and "passively" cooling the gfx card. I used quotes there because it isn't really passive when you have the case fan blowing on it.
 
Just opened up the case. Seasonic PSU is exhausting into the case, but there is little airflow from it and it is very cool air (thumbs up seasonic). Graphics card fan is intaking onto board. So, I'm voting for intaking the 80mm side so it'll blow onto the graphics card since it idles at about 45 celcius right now with the stock cooler.
