ptelles: It doesn't look like CPU-Z is reading the correct core voltage from your motherboard. Everest showing CPU1 at 1.21 volts is likely correct. Your testing shows that TJMax is not likely 100C. It also looks like Intel's TJ Target of 85C for your CPU would be too low.

Based on your testing, my best guess is that TJMax is likely closest to 90C. Intel says that TJMax is not an exact number but I think using 90C will get you accurate temperatures from idle to TJMax. That would put your reported temperatures above your room temperature at a similar amount to what rge found during his testing. rge tested a Dual Core, but based on power consumption at idle, a Quad would only be about 1C higher during this test. Your additional core voltage might also contribute another degree compared to rge's testing.

9C above your room temperature of 25C equals 34C. If you use TJMax = 90C, your reported idle temperatures are going to be right in the 34C range so I'd go with that.
