Doug, did they specifically say where the probe was? If the dies are producing the equivalent amount of heat, then the heatsink will have the same fin temp in both cases, agree? As you move your probe closer to the die, you would begin to see the temp increase similarly for both dice. It's only until the probe moves to very short distance to the smaller die that you would see a higher temp - the region of higher power density. This hotter region might roughly correspond to the size of the larger die, but this would depend on the conductance in the x-y plane of the heat spreader relative to the conductance through the grease and into the heatsink along the z axis. The conductivity of the former is much higher than the latter (copper 394 W/m-degK vs. Arctic Silver III 9.0 W/m-degK), so the effect will certainly be blunted. It all depends upon where the probe was (not to mention how thickly they applied the grease and those other variables I mentioned). eCo
