Yep... about a year ago, the University of Washington announced the same thing. And according to them, they didn't even need a fan, which is something these new boffins required for their test.

The efficiency of the cooling system could be described as the amount of heat it can clear out per unit of energy it takes to do so. I heard someone run some math (which looked as reasonable as not) suggesting the ion wind costs a few times as much power as the fan it makes more effective.
So overall they might not have changed power efficiency, just efficiency of space, weight, complexity (assuming, of course, that ion wind hoosits are less complex than other high-performance alternatives), and perhaps noise.
I say we turn instead to doping and etching the chips onto diamond and let 'em run smoking hot. ;)

They forget to mention the cost (i.e., power and effort) of removing the ozone generated as a byproduct of the ionization process. Unless of course the designers don't care about ozone in the locality of a computer using their newfangled technology.
Perhaps they could design some sort of liquid cooling system. It would be simpler, cheaper, already available off the shelf, doh!

the think is that it doesn't take a lot of current to kill my processor either - think static electricity, which can exceed 10kV at some ridiculously low amperage...

The next step is to put millions of these little miniature fans onto a backpack, or a special suit, so that people can fly up into the air, propelled by gusts of ionised wind.

Big problem I see with these high voltage cooling schemes is that they attract dust via electrostatic attraction, just as an Ionic Breeze or the screen of a CRT television. We all know how dust free the interiors of our PC's are after even just a few months use...
Is an ionic wind anything like static electricity? #

Would it draw the dirt and dust off the heatsink for my CPU as well? No dust on your heatsink is bound to be worth something in terms of efficiency.

Are these figures right? surely it should be 95 Farenheight (being the US) I certainly wouldn't want to have any CPU of mine getting up to 140 Centigrade!

This test was a prototype using 1000 volts across a 1cm gap.
If the requisite voltage follows an inverse square law, the hoped-for 1 micron gap would need only 10 volts.
My thanks to The Register for actually reading the research paper and providing the experimental conditions that were absent from the Purdue press release.
