winewood, the heat concentration deal has been simulated by a number of sources to behave in the way that I describe.
The images were intended to be more one of a pictorial respresentation of the heat concentration patterns by using what is becoming a well known reaction to heat between a certain thermal paste and copper.

I was unable to determine if the heat circle was outside the diameter of the cpu area... if so how much. If the circle didn't expand outside the die area that would be useful.. if it spread by 20-30% outside of the area that would be useful too. I hope you understand why I am asking, I really have NO way to determine where the chip is under that thing from the pic without going into some abstract measuring.

Okay, the following picture highlight the heat-spreader outline in blue, the center of the heat-spreader in light blue, and the rough outline of the CPU die underneath in green. It's a little bit awry because the picture was taken at a slightly isometric angle, so take this as a rough approximation of the die location.
