Noctua provides more details about how its active noise cancellation for fans will work. The company is working together with RotoSub on a cancellation wave that is produced within the fan, using multiple magnets and a microphone. The first products based on the technology are expected by Q3/Q4 2013.
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.
