You have probably heard of noise cancelling headphones, but now Noctua has created a new type of noise cancelling fan in the form of the Noctua NF-F12.
Noctua’s NF-F12 noise cancelling fan uses a technique that modulates the rotating speed of the fans blades allowing the sound of the rotating fans to be reduced. Watch the video after the jump to see it in action.
“First working prototype of a Noctua NF-F12 120mm fan with integrated RotoSub Active Noise Cancellation (ANC) technology running at 2500rpm. The development goal is to achieve a broadband sound signature that sounds more agreeable to the human ear and a similar overall sound pressure level as the original 1500rpm Noctua NF-F12 fan, resulting in 80% more airflow and 120% higher static pressure at the same noise level. Noctua and RotoSub aim to achieve this goal and have the product ready for the market by Q3/Q4 2013.”
More information is available in the Noctua’s PDF brochure (page 20).
