My System Specs

Default What way does the card push air?

Which way does a video cards move air? Does it suck it in and go like this?


Or does it pull it from outside and exhaust into the case like this,


So how does this work? I've always sorta wanted to know how a PCI cooler would help if it was blowing cool air on the card, or sucking it out from the fan and out the back of the case so any help would be great.

Presuming you have a similar cooler on your GFX card, crank the fan speed and put your hand behind your case.

It typically blows/exhausts out the back, so like your 1st drawing.

unless you reverse the wires on the fan it goes out the back :) fresh air towards the blower area does help, as some form of exhaust on top where heat will emanate, if you can call it that :)

Use a Ligter ( not to close to anything flamable ) will show you air flows. :)

My hd4870 its hard to tell, it blows out but just barely. And ive cleaned up all the blades and fins. Seems like as much hot air gets dumped in the case as goes out the back.

No.1
Axial fans pull air from the centre and push it out.
Reversing the fan greatly diminishes efficiency

diagram 1...it sucks in at the fan and blows it out the vent holes on the back of your case.
