I just got Pro/Wildfire with Mechanica including the thermal simulation module and had to try it out on something. I decided to model the stock heatsink from my P4 and constrain the temperature at the die surface to the max allowed by Intel (165 F) and set the 'h' value at 150 W/m2*K and max power consumption of 66.2 W (2.4C). Here is the results
Kind of lends me to believe that the stock heatsink may not be enough for the 2.4C running at full bore.
CPU temps of 165F (74C)? Not sure if you'd ever really see that.
I'd sure hope not but that is what Intel reccomends as maximum die temperature. I was watching my CPU temperature when running the analysis (took about 6 min, solved 150,000 equations and made 5 iterations) and I only saw around 56 C.

I take it your thermal model doesn't take into account air movement. As far as I know, Intel always reccomends some kind of air movement across the board in all the whitepapers.
