I'll check the contact, make sure it's not bent or anything stupid, and see if I can find something suitable to clean the gunk off so I can squirt in some artic silver ^^
So... refitted heatsink, applied Artic Silver 5, ran for half an hour, refitted again to see what the original fit was like. Nice even footprint in the paste, and a near-vacuum seal that was quite hard to break. I'm 100% sure the HSF is properly fitted this time. If I stick a finger in the fan, the heatsink does warm up, though the only bits I can get at are pretty far from the centre where the heat is so it doesn't get overly toasty before I chicken out. Back of the motherboard behind the CPU is around skin temperature.
Core Temp shows load temps of 44-47 degrees, stock speed and voltage. Gigabyte EasyTune says 41-42. Speedfan comes up with 42. TAT says 58-59.
Pardon my french, but WTF? Now I've got 3 sets of numbers for the same temperature reading... even allowing for a motherboard sensor, and an internal sensor, something somewhere is fibbing or reading the numbers wrong!
Life would be so much easier if they'd just decide on a way to read CPU temperature, and not all put their own slant on things =(
With respect to those who'd advise going with TAT, I'm gonna take the majority vote on temperature, find my OC limit without a vCore boost, and (after a good long stability test) just sit back and be happy with my first dual core system. Tis only a number after all, and I can't be arsed worrying about it unless things are starting to get unstable =)
Thanks for the advice though, and I'll post my OC and Core Temp/TAT for reference in a day or two ^^
