Ive had an antec 900 case for a while but my graphics card would always heat up so im wondering if the direction my side panel fan is pointing is correct. I have it as an intake fan, and im wondering weather its better airflow to have it as an exaust fan. any help would be appreciated.

Hello
I tried the side fan as exhaust and my temps went up. I found the side fan a lot better as an intake fan cause it cooled my northbridge aswell as my GC.
If your still worried about your GC put the middle fan in, that does drop a few degrees off your GC and mobo.

I Use the front 2 case fans on low the side panel fan on low and the top fan on low. My mobo temp never seems to go above 32c or below 28c, it did drop to 24c when i had the middle fan in.

The side fan should pull air in, this pushes the hot air away from the video card and feeds it cooler air.

It also balances off the intake to output ratio of this case.

And, if I'm not mistaken, the Antec 900 manual/pamphlet explicitly says to do this.

Manual? whats that?
I must have tossed it
