Wriggling Heat Sinks

Posted by chrisd on from the wow-that-is-just-so-cool dept.

YourHero writes "Purdue researchers have come up with a new way to cool chips, in about 2 years. Just build a bunch of little piezoelectric fans (the waving kind, not the spinning kind). Since they don't spin, no bearings, less self-generated heat. Since they don't have magnets, no electromagnetic noise problems. And, of course, super-efficient. A press release and abstract for your reading pleasure. Formal presentation at THERMES 2002 Jan 15th."

    Can somebody please enlighten the irony nazi as to why electromagnetics are noisy?? Granted that I don't have much experience with electromagnetics, but the 90 in 1 Science electric kit that I had when I was a kid made absolutely NO noise, even when making the electromagnetic experiments.

    I even saw a electromagnet on a crane once pick up a large car. I don't remember any noises involved (except for the crushing car).

    Yet, the article mentions that electromagnets are noisy???
