Already a couple of years in row Austrian company Noctua in collaboration with RotoSub trying to bring to market fans with patented active noise cancellation. Corresponding prototypes each year are brought to the exhibition Computex. The production of Noctua fans with active noise cancellation will begin by the end of this year, and they will appear on sale early next. According to preliminary estimates, the presence of active noise will increase the performance of some fans models by 80% at constant noise level.
Characteristics of the noise emitted by the fan technology RotoSub, are measured using the built-in microphones, and then they are processed by a special processor and using the patented built-in fan speaker , suppressing its own noise. It is noteworthy that the noise reduction works in both directions relative to the plane of the fan.
Surcharge for availability of this function can reach 50-100%, depending on the model of the fan Noctua.
