I have a Northwood 1.6A overclocked to 2.2. I was using the stock Intel heatsink/fan combo with the tim removed and the bottom of the heatsink lapped and TYpe 44 heatsink compound between the chip and heatsink. During 3D mark and Jedi Knight demos, the high temp was 118 and the average was 102. I removed the heatsink, cleaned the chip and mounted the Sunflower first using Artic Silver 2. Temps were then maxing at 131 and averaging 104. I removed the SUnflower, cleaned it, and applied the Type 44 coumpound and got the same results. Removed and cleaned the whole mess and re-installed the stock Intel HS/Fan and got temps as low as they were before. ANy ideas what's going on? I know the copper on the sunflower doesn't cover the entire heat spreader on the CPU.
