So you have your little hotplate of a CPU cooking away in your computer and have to mount a heat sink and a fan on it. Usually that is yet another power drain. Then along comes MSI with the best idea ever (other than using an efficient and cool CPU with a fanless cooler)- use the heat to run a Stirling engine that turns the fan. The hotter the chip, the faster the fan.
It is probably an idea whose time is past, as both Intel and AMD are engineering the waste heat out of their chips, and it isn`t going to work in a notebook computer. But it is still clever. ::Tweaktown via ::BoingBoing Gadgets
