Tjmax determination

Hi Fiery, we're having a discussion in Overclock.net on processor temperature readings. Aida uses Automatic by default, and we were wondering is this a static preset based on the processor or is it a value supplied by the CPU itself on recent processors like my i7 6900K?

Thanks IA for some insight into this!

On Nehalem family processors it's detected using a CPU register.  So there're no pre-defined values.  Older processors (like Core 2 Duo) the CPU didn't have the Tjmax value encoded in a register, so we have to use pre-defined values.
