I have a little problem here. My Q6600 already has Arctic Silver 5 thermal paste applied on it for about a year now and I'm buying a new HSF to replace my broken Arctic Silver 7 Pro. This new HSF I'm buying already has factory thermal paste applied too, so I'm not sure if I should wipe the paste off the new heatsink or leave it on?
