MSI ECOlution Chipset Cooler  (Source: TweakTown)
MSI ECOlution chipset cooler operates on the Stirling Engine Theory

MSI has designed a new chipset cooling fan that is able to operate without electricity. MSI’s new chipset cooler, which is accordingly dubbed the “Air Power Cooler,” offers all of the benefits of a cooler with a fan without drawing any power.   

Energy efficiency of fans can make a large difference, especially in enterprise environments where hundreds of PCs are running at once.  Although passive cooling is always an option, it doesn’t offer the cooling capability of a fan.

The new MSI cooler isn’t a passive cooler but actually uses a fan to cool the chipset without using any electricity. Ironically, the fan gets its power from the very thing it’s trying to remove — thermal energy.

The system is based on a beta Stirling engine. As hot air expands in the system, it applies pressure to the central piston in the heatsink pushing it up. The piston's movement upwards rotates gears which in turn spin the fan. Thermal energy generated by the chipset is converted into kinetic energy.

The fan blows through a common looking finned radiator to disperse the Northbridge’s heat production.

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 isn’t hot enough, the entire system will not run.

MSI is working on the cooler with Taiwanese company Polo-Tech. The powerless fan is expected to make its debut on MSI’s ECOlution during CeBIT 2008.

the chipset needs to be at 60c before it starts working but the hotter it gets the faster it spins

I'm not sure everyone would even want their CPU's hitting 60c to begin with. If that's the only time the fan starts up then there will be some problems. I'm sure it still runs when it's below 60c.

Nvm, chipset cooling not CPU. For chipset I guess it would be ok.

Not only is it chipset, but 60 °C isn't that big a deal. My CPU runs at 66 °C (Overclocked 4.0 GHz Pentium Extreme Edition at 100% usage all the time due to distributed computing,) pretty much constantly. And I have a reasonably high-end cooler.

With a stock Intel cooler, a Core 2 Duo at stock speeds can hit 50 °C under load. And that's with good case cooling. In a bad case, I've seen stock CPUs hit 70+, easy. Older Pentium 4 notebooks under load can hit nearly 100 °C.

I disagree. There is no set temperature that good for a CPU (or chipset), but I have met people on both sdes of the spectrum. Some don't want their entire PC getting above 50c, others run 65c 24/7.

I personally would not run my CPU at stock. My chipset may or may not be slightly oc'ed. I would not be running on stock cooling. I would not like my CPU to run 24/7 over 50c, maybe 60c at unusually high load. My other components may get warmer, but I would try to preserve one of the most expensive parts on my build.

It comes down to opinion, people differ. Nothing works for everyone.
