Real Temp - New temp program for Intel Core processors

kemo: That test proves it. Both sensors are stuck at a Distance to TJMax of 55 just like you thought.

I don't think that running your CPU at a hot temperature for months damaged anything. These sensors weren't designed to report accurate temperatures from idle to TJMax and it's likely that your sensors perform exactly the same as the day you bought your CPU. At least they're sort of accurate when the Distance to TJMax is 55 or less as long as you correct for the difference in TJMax for each core.

speckled10: Accurate TCase temperatures don't exist. That's the reason why Intel gave up on them and doesn't use TCase temperature information to control their CPUs anymore. Thermal throttling and thermal shut down is all based on the data coming from the core sensors. If your core sensors aren't sticking like kemo's and you check the calibration of the core sensors, most of them are quite usable. Don't make comparisons between TCase and core temperatures. Out of the box and as is, you're comparing two inaccurate sensors which is meaningless.

2) Starting with Core i7, Intel stores TJ Target information within each core of the CPU that RealTemp, Core Temp and Everest are able to read. The problem is that this number is still only the TJ Target and the actual TJMax for each core may not be exactly the same as the TJ Target. There is still slope error where these sensors move at a different rate than the temperature changes at as well as TJMax not being an exact number. Core i7 is a big improvement over the 45nm Core 2 sensors but there's no such thing as perfect sensors. All sensors need to have the calibration checked.
