I think I lapped the TRUE C pretty well; It was lapped on a coffee table glass up to 2000 grit. The CPU was not flat and I didn't bother to lap it, so it wasn't receiving the TIM well. I put a rice sized blob in the center of the heatsink and seated it, didn't bothering to check it, thinking it would evenly spread out, but it didn't. So either I need to put on more tim, or better, lap the CPU. The 8650 is a joke I made with a friend, it really is a E8600
