Hello people. For a long time, I thought that the graphics cards flow the air out, so that the card didn't get super hot. But today I googled it up and it seems to be floing the air in the graphics card. But some pictures still show that the fans push the air out. And here I got confused. Please help me solve this dilemma.

IMHO, when the fans blows the air out, it helps to keep the temp low, but when the air gets sucked in... The room temps change, and so it can get hot, or it can get cold, and if the airs suck the air it, the hot air comes in, card heats up. Right?
 
Solution
The fans suck the air in and the heat comes out of the exhaust of the card. Room temp won't change at all, even a reference R9 290x can't do that. (used to own one)

Hmm... ok... I thought it to be the opposite way, but if the air blows in..

This is kind of understandable, because in some cases, the PSU is attached at the bottom, not top, though still, I need time to get used to this.

Would you recommend attaching the fan to the bottom then if there is room for that? I have it on top instead, to blow the CPU hot air out. Or at top it needs to be going inside the case too?
