I wanted to lap the stock NB heatsink and apply AS3, but when I look at my motherboard the heatsink is held on by two plastic pegs with springs to keep the hs on the chip. As far as I can tell, the only way to get the hs off is to break the plastic pegs. Is there some simple way to take them off that I just don't see? Also, if I do break the pegs, how do I secure the hs back on? Thanks for helping
