Ionic Winds Chilling Your Computer

Iddo Genuth writes to mention The Future of Things online magazine is reporting that Kronos Advanced Technologies in cooperation with Intel and the University of Washington claims to have developed a new type of ultra-thin, silent cooling technology for processors. The piece covers many of the cooling technologies currently available, how their new corona discharge cooler works, and a short interview with several of the key team members.

Ozone

I have worked with tesla coils for years, I can tell you this is like begging for a headache! That thing would make a nice amount of ozone, and what does ozone do to living things and metals boys and girls?

Seconded. With so many physics inaccuracies in the 'overview' alone, one becomes dubious.

Exibit A: "Modern heatsinks are incapable of effectively cooling high-end CPUs, not to mention high-end GPUs, without the assistance of a fan." Tell that to owners of Tuniq towers.

B: "The most popular method for cooling modern computers is based on pushing air using fans. This method is sometimes combined with passive cooling,..." Sometimes? Anyone tried pointing a fan at a chip and praying recently?

C: "Active cooling is much more efficient than passive cooling alone and is also relatively cheap." By what measure of efficiency? Not power consumption. I assume they mean efficacious.

D: "Water has a higher specific heat capacity as well as better thermal conductivity relative to that of air (meaning water can transfer heat over greater distances more efficiently than air)". No, that's not what that means and the bogus interpretation isn't even accurate (never mind precise). Tell that to a jet engine exhaust. "higher specific heat capacity as well as better thermal conductivity" means it can soak up more heat per unit volume, and it can pull that heat from a smaller area than in the case of air. Physics 001.

Then they describe what sounds like "point a fan at a chip and pray". Unless ionised gases have some miraculous thermal properties I have never heard of, how do they get around the surface area problem. Aha, from TFA, they're targeting mobile devices. So these things have pissant cooling power. Anyone else concerned about putting ionised gases (aka free radicals) near their face? Advertising bumph. Case closed. How sad.
