I fixed my temp issues, reseated the HSF to be safe, and when I took it off, there was a huge area (about 1/3rd) of the chip that had only the smallest amount. I think I sat the HSF down at an angle and when tensioning the clamps, may have pushed it mostly to one side. I did a more thorough job in spreading out the AS5 with the credit card method this time, and first time booting it up, idle temps have dropped a solid 6c, down to 29c. I bought a tube of MX-2, but when I saw how bad the tim had spread, I decided to give AS5 another shot. Worst case scenario I have to reseat it again, but next time won't have a curing period, heh.
