Thermal Transtech Int'l Corp has let Frostytech know about a pair of new heat column based heatsinks for GPU and CPU application.
The NPH 775-140 HC & NPH 1366-140HC processor heatsinks use 33mm diameter heat columns, and a fairly standard extrusion of bifurcated aluminum fins. The heatsink comes in socket 775 and socket 1366 variants.
The GAT-350HC is a VGA heatsink, but instead of a solid copper core it uses a compact 28mm diameter copper heat column and 80mm fan.
Frostytech has so far been unable to track down accurate wattage values for the upcoming socket 1366 Nehalem processor family.... so if you've got a copy of Intel's thermal design guidelines handy for this next generation of processors, please send it in anonymously. :-)
