This looks interesting.

"MSI has designed a new chipset cooling fan that is able to operate without electricity. MSIís new chipset cooler, which is accordingly dubbed the ďAir Power Cooler,Ē offers all of the benefits of a cooler with a fan without drawing any power." Shocked

Looks like MSI is reallying going green.

I saw that and it seems like a really cool concept, but pretty useless for those who really need it. Im sure that thing doesnt push more than 10CFM.

"MSI tells DailyTech that the system is able to convert 70% of heat power to kinetic energy. It is important to note that enough heat must be supplied to spin the fan blades. If the chipset isnít hot enough, the entire system will not run."

My favorite two sentences.  A real-world proof of the concept that nothing is ever 100% efficient - for those testing the idea  Wink

Of course. If something was 100% effecient, we wouldn't need new innovations all the time.

In most cases where a chipset only produces anough heat to run the fan then that needs to be the point where the chipset needs the extra cooling. If ambient temp is 25C and the Stirling needs a 25C differential to operate then that means the chipset will need to rise to 50C to get extra cooling. Considering that chipsets have been running in the 50C-65C range for quite some time then we might see a use. Can is keep the chipset below 55C?

This being the first run, I expect someone will produce on that runs 80-85% eff.

You gotta give them credit. They're being innovative, which should lead to a more practical version. I guess having a fan that doesn't use PSU power is a benefit in any respect.

I guess this fan is for those who have maxed out their PSU wattage and desperately need a fan. haha.
