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. ;)

Increased efficiency or just efficacy?
