I just recently bought a vigor gaming monsoon 2 TEC/heatpipe cooler and a tube of artic silver to replace the stock setup on my fx-60 , but i'm not sure how i should go about cleaning off the old thermal grease that came with the chip. I'm sure getting as much of the old stuff off for the artic silver to work would be best, but i'd hate to damage the chip or waste a lot of time scrubbing it...any advice will be much appreciated.
