Quoted :
This is the first public release of Real Temp which is a temperature monitoring program designed for all Intel single Core, dual Core and quad Core processors. Each core on these processors has a digital thermal sensor (DTS) that reports temperature data relative to TjMax which is the safe maximum operating core temperature for the CPU. As your CPU heats up, your Distance to TjMax will decrease. If it reaches zero your processor will start to throttle or slow down so obviously maximizing your distance away from TjMax will help your computer to run at full speed and more reliably too.
Other software like CoreTemp has taken this knowledge and tried to work backwards to convert DTS data to an absolute temperature which most users are more comfortable with and would like to compare.
If the DTS is reading 50 then you know you are 50 degrees away from the throttling point. If the maximum safe operating temperature for your processor (TjMax) is 85C and you are 50 degrees away then your processor must be running at an absolute temperature of 35C.
Absolute Temperature = TjMax - DTS
The formula is dead simple and you don't have to be smarter than a 5th grader to figure it out but there is one small problem.
Intel does not publicly document what TjMax is for desktop processors. TjMax is fully documented for their Mobile processors but not for their desktop Core processors. Without this reference point, your absolute temperature data could be meaningless. Intel has also confirmed that there is no secret bit hidden in these chips that a programmer can read to determine what TjMax really is. The only thing a programmer can do is guess at TjMax and if he gets lucky and the reported temps look more or less believable then everyone is happy. "
