Noise reduction specialist RotoSub and renowned quiet cooling fan manufacturer Noctua today announced a strategic partnership agreement for the development and commercialisation of PC fans with integrated Active Noise Cancellation (ANC). A first prototype of a Noctua fan with integrated RotoSub ANC technology will be shown at Computex Taipei next week.

Active Noise Cancellation (also referred to as Active Noise Control or Active Noise Reduction, ANC) is the technique of using sound waves to reduce noise by means of an effect called phase cancellation or destructive interference. Lars Strأ¶mbأ¤ck and Mأ¥rten Oretorp from RotoSub have invented a system (RotoSub Active Noise Control, R-ANC) that allows a fan to emit the sound signal that cancels out the original sound of the fan and thereby greatly reduces the overall noise emission.
