Hmm, about the chipset cooling, how about a system similar to the one used in Shuttle SFF´s...

A small and flat heatsink on top of the heat generator (CPU, NB etc.) with built-in heatpipes for carrying the heat away to a large and possibly actively cooled heatsink? The other end could also be a watercooling block.

The only problems I see with this approach is the way of fixing the end of this gizmo to the MB so that it wouldn´t rip it apart or crush the chipset. Torque becomes a major factor as the lenght of the heatpipe increases... Then again it could be mounted so that the other end is supported by a structure that is affixed to the motherboard via it´s mounting screws...

Opinions? Does this sound absurd?
