Ionic Wind Cooling Next Step in CPU/GPU Cooling

Lately, heatsinks and traditional fans have become so large that they are beginning to be obstructive and sometimes too heavy. This has become an issue on the graphics processor front in many ways, as there isn't enough room for large heatsinks, yet GPU thermal exceeds that of high-speed CPUs.

A company called Kronos Advanced Technologies is working on a method of removing heat from devices such as CPUs by using ionic discharge creating a fluid motion of air. This technology has been around for a few years and is used in products such as ionic air filters, which have no moving parts but still move volumes of air and create quite a strong breeze. The same concept is being applied to micro processor cooling.

Despite the advancement however, the volume of air moved over the CPU core is still small because the core surface area is small. Heatsinks are used to increase surface area of the hot surface, so that when air is moved over the fins, more heat can transfer to the air. The Kronos' device will attempt to remove hot air away from the processor core directly without the need for heatsinks. With this method, the velocity of air being moved needs to be extremely fast in order to compensate for the lack of surface area -- and speed is something that ionic air "movers" lack.

Right now, Kronos is still working on prototypes, which it claims are scalable from very small micro coolers to large scale sizes. Power requirements also appear to be quite steep at this point in time. One of Kronos' demonstration shows a heated area being reduced from roughly 50C to 25C using an ionic cooler, but the power supply required around 8.5kV, or 8500 volts, to stay stable.
I doubt it will ever see the light of day.

I agree. This would be wayyy to expensive.

Agreeded, way to expensive. Whats next, ________ cooling?

^^^Insert some stupidly expensive colling method above.

It's called water cooling

i don't see how you can possibly cool a CPU without a heatsink.

Ya know, liquid nitrogen would probably be just as cheap after a while.

How about laser cooling? That's how they cool things to near absolute zero (never gotten there yet) basically they shoot the atoms with lasers to slow them down to the point where they are just barely moving, bringing them closer to the -273c (0 kelvins) mark which is absolute zero, or in other words the point where there is no more heat energy (or movement of atoms at all) left.

Someone already jerry rigged his own ionic cooler. Don't have the URL, but tech relative showed it to me during Christmas.

So it's possible and doable with existing materials.
