I think one thing we can all agree on is, that the chipsets are getting down slowly after nVidia hit the roof (hopefully).

Secondly, you cant just calculate TDP using Icc max and the voltage. Alot, if not all of the time its for very short peaks only. The prime example is x975 vs P965.

It should also be pretty clear that this northbridge cooler cant remove 19W

In that case, we could just aswell run P-Ms with the same cooler. Or mobile C2D/Turion with alitte bigger passive too. To help compare, even VIA CPus tend to use an active cooler over 10-12W.
