Motherboard fan powered by waste chip heat

In Taiwan, Motherboard manufacturing company MSI is working on an interesting technology with new powerless cooling fans in their labs, which harvest the heat from processor with a small Stirling Engine. It all falls under the ECO friendly project, which we hope to see in near future. Since power saving green gadgets is hotly discussed topic, MSI has employed the Stirling Engine Theory to power a cooling fan without the need of electricity.

Heat is transferred from the motherboard northbridge chipset and according to the Stirling Engine Theory it is able to spin the cooling fan and that cools down the heatsink. MSI said that they would put world’s first powerless air cooler to an Nvidia motherboard.

Here is a demonstration video explaining how it actually works.
