85W peak thermal power.

The heat-spreader is 37.5 x 37.5mm in size.

The heat-spreader seems to be around 1.5mm thick.

Oh, found elsewhere that the die size is 193mm^2 - wow - that's a pretty big die.

Edit 2: Could not find an actual statement of the physical X-Y dimensions of the die size of the Opteron, but found a picture of the die here:

The die is roughly 3:2 in size for the edges, slightly favoring the longer edge. My rough estimate is the actual die is about 11x17mm in size. Given a 1.5mm thick heat-spreader, this would mean that the optimal area to focus the cooling on would be about a 14x20mm rectangle. Heat conducting outside of that region would be minimal.
