so you're asking how to put a fan in the case to help cool your graphics card?
if you have a side window, you can cut a hole it in and mount a fan to point to your card. or, if your case layout permits, you can put a fan inside the case on top of a hard drive and point it at the graphics card. i have this set up, with an 80mm fan on my hard drive that helps pull the air from my 120mm fan in the front of my case straight over my card, and to the back of the case. works pretty well.
