Heat Column based Socket 1366 Heatsink Emerges from nPowertek

@ 2008/07/16
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.

performance is up there with 6-heatpipe monsters

Loads cheaper than a solid chunk of copper too, I bet. For the price of some Intel processors, the cooler must cost a third of the price!

not left hollow, there's also a liquid inside, but cheaper then heatpipes.

So... are these "heat columns" filled with anything (similar to a heatpipe), or are they left hollow?
