Ok i put it on last nite. It went ok, i managed to get the stock HSF off, with no issues. I took the rubbing alcohol, put it on a qtip and cleaned the cpu, then cleaned off all the black gunk, from the thermal pad with a qtip. Put the right amount of AS5 on it, then put the HSF secured it, then booted it up no issues . My idle was about 30-31C before and bout 38-40C @ load playing RO for ut2k3. Now it is fluctating about 27-29C at idle and about 35-36 @ load. Im assumin i did this right, cause if i didnt wouldnt the temps be sky high?
