Bring in air or blow it out?

[nick_lerwill]

ok i am going to put 2/3 case fans in my computer i will have 1 on the top and 2 at the back do you think i should hav the 1 on the top bring in air and the 2 at the back blowing out air? what is the most effective way?

well this is the way i have mine as hot air raises and my top fan blews out so i hope most of the hot air goes out and the bottom fans bring air in
Temps idel 21 - load 33 C my pc is in my bedroom and in open space so air flow is 100%
hope tihs helps you
see my sig for spec

Do you have a fan mount at the front of the case or at least some sort of good ventilation grill? If yes i would have the 1xtop and 2xrear all extracting air from the case and therefore sucking in the cool air from the front.

If no i would use a fan for the top extracting that is equivelent in power to 2xfans at the rear pushing air into the case. Not the ideal set-up but one that will at least blow cool air over the top portion of your mobo that can be extracted from the top in a somewhat warmer condition.
