Fans set to pull for cooling

[tp95112]

I was just wondering why dont graphics cards or heatsinks pull instead of push? Coolers like Windforce or Direct Cu II all use push for cooling but why not pull?

I guess pushing the hot air out is more effective than pulling cooler air in

Wouldnt it be somewhat the same?

So hot air can be pushed out in the exhaust of the case rather than pulling hot air into the case where it just stays there.

What about non reference design coolers?

push the air on the small heat-sinks is more effective that pulling, e.g. small chipset heat-sinks have air pushed, and large radiators can have air pulled, since most gpu have small heat-sinks it is better to push the air. all so to wet up the fans as a pull fan will take up more room, so less surface area for heat dissipation can be left. the bad form-factor of the gpu cooler has many disadvantages this is one of them.
