I remember seeing the precursor to this some 10-12 years ago. Can't recall if it was the same company or not. The prototype looked like a block of very densely packed sheets of carbon fiber - imagine a typical car radiator but with finer and thinner fins made of some black plastic-like material - and once energized the sheets would oscillate in a way such that air got sucked through the block at impressive speeds. The prototype wasn't particularly silent. On the whole this idea doesn't seem like it's going to do much for laptops now that Arm is entering the scene. Maybe it'll make a good solution for noisy graphics cards.
