i have a compaq presario pc i bought almost 5 years ago, it has amd athlon 64 3400+ which still has stock heatsink + thermal paste, would it help if i replaced my paste with something else? the last time i tried to remove the heatsink(back in 2006) my cpu came off with it also so im not sure if its possible to get heatsink off now, probably stuck to it too tight now. was gonna overclock my agp card finally until i build a new pc a few months from now. going to buy a 2nd hdd to store my games/music/movies on so not sure if i should waste my time getting paste to replace the stock stuff if its possible to remove the heatsink now?
