Noctua shows off noise-cancelling PC fan prototype

Quote:
There are plenty of PC hardware components on display here at Computex Taipei, but Noctua is demonstrating a fan with integrated active noise-cancellation, a curio too novel to pass up. The technology was developed by Rotosub, and consists of a microphone, a metal band around a PC fan's frame, and a signal processor. The microphone captures the sound being emitted by the fan, feeds that data to the signal processor, which analyzes the noise and toggles magnets built into the tips of the fan's blades.


Silly me, it is on the front page: http://www.silentpcreview.com/news1264.html
