Hello, I am gonna buy one of those Monarch Computer combos for my next build. Since they don't offer the XP-90 Heatsink, I was gonna take the one off of the one that came from Monarch. I am scared though of ripping the CPU out of its socket and damaging it. How would I correctly reomve the heatsink from the CPU? Also, what is the best way to clean the CPU of the thermal pad/grease? Thanks.
