Ok, i finally took off the IHS, and bolted on my d-tek fuzion.

Very dissapointed with the results, on idle i got 33 degrees, but under load it shot up to about 85 or so (using linpack)

The funny thing is that as soon as I stop the test, it jumps straight down from 85 to 33. And when i say straight, its literally 85 -> 33, in the blink of an eye.

I checked the contact and the thermal past imprint was perfect. I also tried wiggling about the block while linpack was running, but without any change to the temps whatsoever.
