Think the NH-D14 is too loud when running at full speed? The folks at Noctua in Austria think so too, which is why they’ve created a version using active noise cancellation technology developed along side RotoSub. If you’ve ever used ANC headphones, you’ll have an idea on how it works.
Basically, the unit records the sound of the fan’s noise with a built-in microphone. After that, it plays back the same noise, but with the phase reversed. This works best with constant noise, which is why ANC headphones are popular to use on flights. It would also be perfect for the constant noise created by fans, which is why this seems to be such a great idea. The end result is pretty amazing when you turn the effect on and off. You can see it demonstrated in this video:[youtube=http://www.youtube.com/watch?v=AikMzJc9gcY&w=620&rel=0]
As you can see (and hear) the effect is dramatic, and immediate. The only thing you can hear is the sound of the air itself – the fan noise practically disappears.
This is a prototype based on the NH-D14, our favourite cooler in that size range. I would expect the end product to be quite similar to the prototype, as it is already quite refined. Be on the lookout for this one soon!
