I have heard various methods about applying thermal paste. I plan on upgrading my CPU to a 12-Core. I heard the "X" method, and the "Bean" method etc. Since the top of the CPU chip is large (where you would apply the thermal paste), how much (or how large) should be applied? Should I apply thermal paste on both the CPU chip and heat sink or just the CPU chip? I have heard both, but still not sure. Thanks for the help.
