To me it was interesting to find that the coldbug for HT enabled on my cpu is at a significantly higher temp compared to running without HT
Interesting find, though from all the i7 I was testing the temp really didn't helped as much as with E8600 for instance. You are using any...interesting BIOS on X58 Extreme? The normal bios'es don't favour very high uncore from what I have seen untill now.
