MSI employs Stirling Engine Theory
Micro-Star International (MSI), one of the leaders in motherboard technology, will bring new life to old technology with new concept on motherboard products. While everybody is looking forward to have a more ECO friendly design, more motherboard makers are trying to save energy on the motherboard side with PWM design, MSI already has very efficient power design, but we research more than only PWM design enhancement, trying to offer the total ECO solution we now give you the heat transfer power concept on motherboard cooler design!
MSI unique ECO cooler concept, over 70% heat transfer!
The amazing of nature power has taught humans a lot, with the earth’s resources running out and fuels such as petroleum to run-out in this century, now is the time to work harder and find the replacement resources and use what we have learnt from earths nature. After MSI concept solar power notebook system, MSI continued to survey in the pursuit of innovation & ECO power to find other new technology for motherboards, today we introduce to you a solution that’s heat and air power!
Maybe you have already heard about “Stirling Engine Theory”, but in Taiwan, we have great companies that not only work hard on selling products, but also try to investigate future energy solutions. Thanks to MSI and our great partners, we would like to introduce the “Air Power Cooler” based on Stirling Engine theory with great support from Polo-Tech Taiwan, the exclusive heat transfer technical design company with their own patent rights.

The “Air Power Cooler” transfers the chipset heat into air momentum, when the air becomes hot, the air will expand then push the fan to rotate and In doing so cooling the heatsink immediately. After the air moves from the bottom to top of the piston, the air will become heavy to push the up piston down. The better air piston design can transfer over 70% heat power and transfer to air power, that’s great efficiency transfer from Stirling engine theory. In a comparison with solar power the transfer rate is only around 20~30% requiring more surface and as a result cost.

There is a demonstration video available of the Sterling Engine Theory which I have included a link to here
Admittedly the power savings will be small, but I guess on a large scale it has potential if it works well enough. Although my biggest concern is the fact that the additional plastic needed for the fan kind of negates its eco-friendly status over that of a traditional copper silent pipe solution.
Am I way off track? Feel free to verbally assault me on the forum
