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 fan blades, allowing the sound of the rotating fans to be reduced. Watch the video after the jump to see it in action.
How Noise Cancelling Technology Works in Fans
The Noctua NF-F12 fan incorporates RotoSub Active Noise Cancellation (ANC) technology. This innovative approach involves the use of sensors and actuators to detect and counteract the noise produced by the fan blades. By modulating the speed and phase of the fan blades, the ANC system generates sound waves that are out of phase with the noise, effectively canceling it out. This results in a quieter operation without compromising on performance.
“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.”
Benefits and Applications of Noise Cancelling Fans
Noise cancelling fans like the Noctua NF-F12 offer several benefits, particularly in environments where noise reduction is crucial. For instance, in data centers, where multiple fans operate simultaneously, reducing noise can significantly improve the working conditions for staff and reduce overall noise pollution. Additionally, in home or office settings, quieter fans can enhance comfort and productivity by minimizing distractions.
Moreover, the increased airflow and higher static pressure achieved by the NF-F12 make it an excellent choice for cooling high-performance computer systems. Gamers, content creators, and professionals who rely on powerful PCs can benefit from the improved cooling efficiency without the accompanying noise.
