How to keep my HD 4850 cool

[hopkiller]

Ok need some help here. I need to know if i should go buy a VGA cooler so i can overclock my GPU. Ive been trying to overclock it today and it is stabe at these settings
690/1118 but it gets hot way too fast and crashes. It passes the test to see if it stable but it just gets too hot. Is there anyway to fix this. Ohh and my fan is at 65 percent.

put the fan to 100% and stick on some headphones..... thats how i game

Also could get a pci slot cooler fan to go directly underneath the gpu to help pull some of the hot air off of it and outside the case.
