Which way should the fan go?

post #1 of 5
Thread Starter 
I've got two 480's running in SLI, and I've got a fan on the case that blows into it. What I really want to know, what is most effective to bring down temps? I got one fan in the front sucking in air, one in the back sucking out, on in the top sucking in, and the one on the cards sucking out. Should I put it to blow air towards the fan, or keep it as is?

Side fan, sucking in towards your video cards. Concept is, fresher cooler air for them. Plus you keep a positive case pressure, which can help reduce dust inside.

That's what I was thinking. But since I just realized it was blowing out, I thought I'd ask before changing it lol. Thanks!

Front sucking in, side sucking in towards the cards, rear blowing hot air out, top blowing hot air out (hot air rises).

That's right...didn't think of that. And the fan for the hyper 212, I've got it sucking in the air from the RAM, which would mean blowing it out towards the back, that one is ok right?
