Did you know you could create a speaker from the spinning blades of a fan? Simply rotate the fins and modulate the rotating speed. It’s actually the basis for the world’s largest subwoofer, which we wrote about back in 2005. Using this principle, Noctua’s NF-F12 integrated noise cancellation fan is able to reduce the racket inside your case by 20 dB, “utilizing a patented RotoSub ANC technology to emit anti-noise directly from the fan’s own blades.” They hope to achieve 1,500RPM noise levels from a fan running at 2,500. Of course this doesn’t beat liquid cooling solutions, but these can get unwieldy. There’s no word on price, though availability seems to be set for somewhere in the latter half of 2013.
