Well i thought i'd put in a 80mm fan and hook it up 12v. Big mistake. Hooked it up worked fine but guess what, FRAG. Unhooked the new fan and put the original back in and still frag. I can't see how switching fans would cause this so the only thing i can think off is maybe a soldering joint on the chip install moved or something so i guess it's back to the chip install for me. Dammit i thought i'd never hafta deal with frag again.
