MSI develop Hot Powered Cooler
Motherboard company MSI is working with Taiwanese company called Polo-Tech to develop cooler for chipset which is powered by heat, this engine is also known as 'Stirling engine'.
Invented by Reverend Dr. Robert Stirling and patented by him in 1816 this engine works by temperature difference between hot tube and cold tube inside it.
MSI powered this engine from the heat taken from its northbridge chipset then sterling engine will convert the heat to mechanical force that will drive fan blade to cool its chipset, ergo.. the fan doesn't need electricity at all.
MSI said that they would probably be the first to use powerless air cooler to an Nvidia motherboard.
