After seeing the VapoChill Micro ThermoSiphon roll out this past summer, Scythe has started out recently in Asia with the Katana 1000.
Basically, it's the same foot-print as the Micro, but in a heat-pipe kind of way.
Performance? I can't read Asian script.
The only English I've found is:
CPU: Intel 370/478/775/ all Xeon's, AMD 462/754/939/940.
Heat-pipe fin area: 98x96x130 (very much the same as Micro)
Fan: 92x92x25 / 2000rpm / 25dBA / 35.12CFM (like the Micro)
Weight: 300g (55g less than Micro)
Price: 2,800 Yen / $30 Euro / $33USD
Only time will tell if this product is successful and comes to the shores of North America.
