I haven't bothered putting the ram fan on. Just slapped the new i7 stuff I ordered together to make sure everything works and my GTX285 needs to be RMA'd as it is rebooting the computer on some pretty simple stuff. Supposedly, overclocking can/does cause the ram to heat up. I am not much of an overclocker, but the mild OC's I have done didn't really heat the ram up much. With this build and once I get my watercooling case completed, I will probably buy an i7 975 cpu and hopefully go over 5ghz as a 24/7 clock. Maybe then, the ramn fan will actually be useful.
