Asetek makes Micro phase cooler
The Inquirer has the goods on an interesting new phase change cooler from Asetek that will apparently sell for less than $40.
The VapoChill Micro PCU cooler is filled with hermetically sealed gas/liquid captured in chambers and exploiting phase change cooling principles. The company claims it's much more efficient than the currently heavily used heatpipe cooler principle.
Although much larger than standard heatsinks, the Micro cooler is quite a bit smaller than traditional phase change coolers. With a sub-$40 price tag, it could become a favorite among overclockers or enthusiasts looking for lower noise levels.
