im currently using a stock heatsink on my i7 930 0c'd to 3.6ghz, a friend of mine is getting a new cpu heatsink for his 965, he said i could have his 965 heatsink because it would provide better cooling. if i use it will i need to reapply thermal paste or clean the cpu first? (the 965 already has thermal compound on it apperently)
We're talking about the i7-965 heatsink, right? Not the Phenom X4 965?
You very much want to clean the heat spreader of your i7-930 before installing the new CPU cooler. A Q-tip and isopropyl alcohol (rubbing alcohol) gets the job done.
You won't need to add any thermal compound since the right amount is already on the CPU cooler heatsink.
the 965 already has thermal compound on it apperently
If the 965 heatsink hasn't been used before you won't need to add thermal compound.
It it has been used - you'll need to clean the residue off the heatsink and then apply new thermal compound to your CPU. OCZ Freeze or Arctic Cooling MX-2 are thermal compounds I like.
thanks for the replys guys. no the i7 965's heatsink hasnt been used. my friend left that out because he hasnt finished building his system. hes waiting for his new zalman cooler to arive before he fires it up lol. so hes giving me his (i know i said 'old' but its still in its clamshell packaging and hasnt been used lol) heatsink... so when i remove my old i7 930 heatsink will i need to clean the cpu or can i just slap the cooler straight on lol, thanks
You'll get the best result if you do clean the heat spreader on your CPU.
But you'll have a chance to eyeball what's left on the CPU and you probably could get away without cleaning if there are no large scraps of thermal compound remaining.
