Jozef re <<What's the approximate relation between the processor case temperature and the die temperature?>>

The resistance of the thermal lid itself is less than 1 degree, the main temperature rise happens in the interface which is filled with sliver paste. That conductivity can be as much 90,000 W/m^2.k, so with die power density of...errr... 50 W/cm^2, then total temp rise is 6 degrees.

If the die size is reduced (power density increasing), then it gets that much more difficult. So bigger the die, the easier it is to cool it.
