Sorry, I have been swamped and not been able to get on the net for a bit. But it look's like that was the issue. I ALWAYS use some kind of silicone based paste for my cooling needs on AMD's, they are notorius for being ovens. I had assumed (sorry) that it came with a proper themal medium to fill in the gaps between the heatsink/proc. My current heatsink came with that pink pad they like to use since the die is so fragile on those, but they are horrible for heat transfer. And just so you know generic works just as well as premium paste, I've done the tests. Good job!
