Best Graphics card brand for cooling/fan??

This is literally the last thing I need to complete my build and I can't chose MY BRAIN IS FRIKKIN TEARING APART.

GPU: Radeon HD 7850.

I'd like the brand with the best fan/cooling system. I don't want my GPU to melt over the summer (it's probably gonna be like 500 degrees this year) so I need to make sure the fan is excellent. I don't care about warranty that much. Oh and my case is an antec three hundred illusion so i think it has good ventilation.

List:
-Sapphire
-MSI
-XFX
-Gigabyte
-Asus
