Nobody knows what the Tjmax for Core2 Duo desktop processors is. As such, it is impossible to determine the absolute core temperature of the processor.

I think your method, unclewebb, although logical, is flawed. You are still *assuming* many things to make you calculation.

You are also assuming that there is no thermal gradient within the processor. You assume that Tjunction and Tcase are equal.

You assume that the air inside your case is the same temperature as the air outside the case.

You are assuming that Tjmax is either 85 or 100.

I see what you are shooting for. But you method is based on a LOT of assumptions that I don't see the point. Why do you need to know the absolute temp, based on assumptions, when you already know the relative temp with certainty?

CoreTemp 0.95 works PERFECTLY with any Core2 processor because it measures, and can be configured to report, the DTS...which is all you need be concerned with.
