Yah, was bound to happen with the whole magnetic thing, I'm suprised they didnt do it earlier. The idea has been around for a long ass time. Hehe and i see it in a computer fan, Intresting, but it cost an extra micro-chip im guessing, wonder what the timming of the magnets is set on.
well I hate to breake it to yah but conventional fans have magnets in them to so I wouldn't worry to much about the fan f*cking up you HDD
also because the fans have been tested in computers
