Specialist cooling company Noctua decided to work with RotoSub in order to deliver a low noise cancellation solution which would let you fly the air cooling flag high, although it does dispense away with all of the noise. This is made possible with the introduction of active noise cancellation, which so happens to still be in prototype form, but was built based on Noctua’s NH-D14 cooler using a twin-tower heatsink. How does the active noise cancellation work? It relies on a combination of mic and speakers, as the microphone would pick up the sound created by the cooler, before the speakers output the same sound albeit with a phase difference – which more or less cuts down the level of noise by a significant amount. Neat!
