A CPU simulator seems the only way to keep a stable even temperature. Some results with a cpu would be as varied as much as the tester because the heat load will be completely different!

There is also the issue of the location of the heat generation.
It may be possible to generate equal amounts of heat with two programs, but in one case the heat is disproportionately in the floating point circuitry as compared to the other.
Does anyone even know where the temp sensor diode is located on the die? (Central? One edge? Near what subcomponent(s) of the CPU?)
