I finally got it working by right clicking realtemp.exe and selecting run as administrator from within vista 32.

Thanks unclewebb! Rge - wish i had a heatgun!
But you are showing something interesting nonetheless. If your cpu temp is accurate, the gradient between tcase and core at steady state idle, and at steady state orthos load, is so small it gets lost in measurement error, ie 1C or less. The test i linked to earlier with the thermocouple on core versus case temp showed the same, only 0.4C gradient at steady state idle.

Also, the fact your cpu temp scales with core from idle to load, irrespective of absolute cpu calibration, suggests the notion that large gradients of 10-15C occuring on orthos load versus idle, are suspect, and here we have a known tjmax.

Every piece of actual data i have seen has supported unclewebb's conclusion that less than 1C gradient exists between core and tcase at idle, and likely the same occurs at steady state moderate loads like orthos, and steeper gradients occur primarily when load is changing, or may take programs like TAT to load the cores to the point one sees a constant 4-5C gradient. But cant test to know if even that is possible on the new 45nm, since TAT is not compatible with them.

But yeah if you could measure tcase directly and show its same as core, I think that would put any remaining doubt to rest, but for me, not much doubt remains anyways.
