Micro Star International has developed an innovative technique to keep your motherboard cool while simultaneously increasing energy efficiency. As per “Air Power Cooler” concept, the heat generated from chipset is converted into kinetic energy (with 70% transfer efficiency) to keep onboard fan going. Thus, resulting in power savings. The concept definitely makes sense. As the motherboard is going to generate heat continuously, its better to convert this heat into equivalent energy to power fan rather than using another source of energy. The company plans to implement this technique on their ECOlution series of environment friendly mainboards to keep your machine cool.
How does it actually work?
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.
