IC Diamond is some good stuff but you dam near need a bulldozer to spread it, crap is dam near a sold. LOL
I used AS5 for the past 6 years until I decided to try a bunch of them on january. I tried 7 diferent of the most rated brands, and IC Diamond came out on top. The diference to AS5 is amazing.
having said that, the thing is hard as hardened cement! but I found a solution: heat up the siringe by dropping it on hot water and heat up the cpu and cpu-block surface with a airdryier. That will make the the IC diamond spread like butter.
