Hi there just a quick question. Im thinking of trying to push my cpu to 2.8 but i will need a new cpu fan. Last time i read this section a lot, the artic freezer 64 was very good, is this still ok? Also, when i take my old one off, there is some of the old thermal paste stuck to the top of the chip, does this need removing, and if so whats the best way to go about it? Cheers!
