My Everest Ultimate and CPUID Hardware Monitor both show my idle cpu temp at 28C @ 4.1GHz, while in the bios the cpu temp is 32C? I would probably believe the latter, and add 4C onto the Windows temps.

Some other posters have confirmed that thermal throttling starts at bout 95C, which would bring the tjMAX of 105C into question. I guess we could then add 10C to the core temp readings in Windows, also.
