What type of case do you have? Is it the type where you can remove the side pannels? I found it usefull to mount two case fans to the side of that. Just put the fan up to side of the case trace around the inside of the fan and take a scroll saw to cut it out. It significantly increases air flow in your case, plus it cools down all of your cards, especially your video card if you have one that runs really hot like mine. Its also a good idea to actually cut the cover away from the back of your powersupply, I've found that that decreases air flow and creates extra noise.
