A great number of CPU announcements have come down the pipe recently. First it was VIA announcing their new Isaiah CPU, picking up where the C7 left off. Then it was Intel with their Silverthorn and Diamondville (now both known as Atom).
Scythe has been busy too, releasing two new heatsinks. The Zipang (which appears to be an archaic name for Japan) and the Orochi (a legendary dragon with 8 heads and 8 tails). Both are massive- the former weighs 815g, while the latter is a frightening 1285g), and use 140cm fans.
MSI has generated a lot of press recently with their announcement of a northbridge cooler powered by a Stirling engine. While it is interesting, it doesn't appear scalable at this point.
