I'll try to repeat Sunday's tests to some extent tonight. First order of business though is insulating the CPU socket and wb as much as possible. I got water from condensation melt on the top of my video card last night. I figure I should check the CPU sooner rather than later.

I also in a moment of clarity thought about the drop in C/W that Les showed yesterday. When I was running CPU back and mobo backside temperatures too I noticed clearly that when under load at high Vcore the motherboard was getting pretty hot (30-35C) and affecting the CPU backside temps. Idle at the same speeds you could see the mobo backside being cooled. This could be the reason for the deviation in C/W at low coolant temps &W; the motherboard becomes far less of a secondary heat source and so the overall W (die+mobo electronics) goes down more than you'd expect. Just a guess though.
