I WAS just wondering, if ive used an intel heatsink for quite a while and I want to replace it with something like the hyper cooler evo 212 cpu cooler, would I have to remove the intel heatsink and scrape thermal stuff of it? if so how would I do it, and how much thermal paste should I put on the cpu when putting the market cooler on it? also is it ok to use the ed500 computer vacuum? it supposed to be safer than compressed air? thanks guys! I have an lg 1150 asus p8z77 v -pro mobo if you're wondering with intel i5 3570k
