Hey, I have a Xigmatek HDT-SD964 cooler and a Phenom II x6 1055T. I'm moving the CPU into another mobo and I believe I will replace the thermal paste. I usually put some thermal paste on the heatsink and spread in into a square with a credit card but this usually uses up the whole tube of paste. So, I'd really love to save a lot of thermal paste! According to http://www.arcticsilver.com/PDF/appmeth/amd/md/amd_app_method_middle_dot_v1.3.pdf , as little as a grain of uncooked rice is much better. Is that right? How should I do it? I mean, I have 6 cores and I don't know if the paste will cover up all of them cores. Or, should they even cover up the cores!? Btw, the base of my heatsink isn't really flat because of the exposed heat pipes!
