Good airflow & vent system for ATI 5770

post #1 of 3
Thread Starter 
hello, i recently bought an ATI 5770. my casing has 2 vents for fans, one on side and one on back, both are 80mm.i have very limited cooling option. so how should i arrange the fans (where to place intake, exhaust fans) for maximum airflow and the fans, how much minimum rpm, cfm should the have?

If now you don't have any fan mounted, any pair of fans will make a difference. When mounting fans the basic idea is that warm air has the tendency to go up. You should make a setup where the air enters the case thru the lower part of the case and exists thru the higher part. You should probably put the side case fan as intake and rear fan as output.

Also, I'm a fan of negative pressure airflow so I'd pick the rear output fan of higher CFM than the side fan, if this options is available to you.

Post some pics of your case, outside and inside; we could give a better advice.

my side fan vent is directly above my cpu, and isn't the cpu fan blows outward? then if case fan blows inward and cpu fan blows outward won't there be a problem? or is the cpu fan blows inward too? how can i be sure?
