Noctua Display RotoSub Active Noise Cancellation CPU Cooler

[Artorias]

Author: Ryan Martin (eTeknix)

Noctua teamed up with RotoSub quite some time ago and Noctua have been working with them ever since to bring RotoSub’s Active Noise Cancelletion (ANC) technology to Noctua’s products. At Computex 2013 Noctua unveiled something very special, the first working prototype of a RotoSub-inspired CPU cooler design.

 

 

On the face of it uses a slightly adapted NH-D14 heatsink and adds an NF-A14 fan to the center. Yet the details are key because the NF-A14 fan has been heavily adapted with RotoSub ANC technology and features a wider 30mm fan frame for higher airflow. The whole design uses a custom designed metal shroud to enclose the CPU cooler.

 

Furthermore Noctua are claiming an impressive full ram compatibility up to 70mm in height, because there is no outside fan. Currently this design is only in prototype and you can see a more in depth video overview of the new prototype below.

This has potential to be either extremely good - or like the Coolermaster V10 - super, ultra shitty. Though I have faith in Noctua.

 

Just hope they nickel plate the fins or something, the 'sheet metal' look is horrible.

Someone techie enough here to explain how this works?

A bit like noise canceling headphones. A microphone picks up the noise generated by the cooler, the noise signal is processed, and "anti noise" is made to cancel out the noise of the cooler.

The way they make the anti noise is that the fan blades have small pieces of metal in them, and in the frame around the fan blades, there's a ribbon of small magnets which makes the fan blades vibrate like a speaker.

Edit: In all my haste, I got it the wrong way around, the magnets are in the blades and the coil to vibrate them is in the ribbon

This is great for those guys who hate Noctua's fan color scheme. The custom-designed hood will cover the fan color. :)

in laymans terms. a microphone picks up the "sound waves" that is being outputted, and gives the exact wave, but with reversed phase. that doesn't mean the sound isn't there, but it has been neutralized to the point that most people can't hear the original sound anymore :)

soo would it be posible too on a normal Fan? for example NF-F12 at 12v

I think Noctua plans to build it in to fans as well, but I think they recon a couple of years with R&D before the system is small enough to fit into a fan. Right now they use the extra space of a complete cooler system to house it all.

I think they're talking about double fan speed with same or lower noise levels as before

k thx for the answer

Well, this is either the greatest or worst thing Noctua has come up with... No friggin idea which one though

Yeah, I know how you can cancel out waves, but I didn't think they'd be able to acoustically cancel out a wave like that. I mean, doing all that stuff digitally on a microphone seems way easier to me because the computer can just combine the two waves so they cancel out each other.

I'm unsure about longitudinal waves (sound) but if you'd get the phase wrong by some degree you'd either diminish the cancelling effect or actually amplify it, right?

 

But I guess it's really impressive that they managed to do something like this in such a small form-factor etc.

FYI: It will still contribute to case vibrations, so this doesn't mean that you can suddenly install a massive tower in a recording studio PC and get away with it :P

I really like the glowing effect on their logo in the heatsink. Just imagine putting this in a dark case and all you see illuminated is this and the Geforce GTX logo from your graphics card and some corsair dominator platinum w/ blue light bars. Nerdgasm.

I can't believe how nobody has implemented this yet, although it probably will not be worth the price and I really don't like the looks :(.

A quit 120mm 2000+ rpm fan is what I expect.

But... but the logo. It glows.

Now I'm waiting for the GPU version.

[ProGearUk]

It looks like it will be good. Let us hope it actually will be oood and is the microphone to ensure the cooler is not too loud. 

[mgsstar]

This is some pretty advanced technology imo. The cooler look very beast and will be able to handle overclocks pretty good.

Let's hope there are no defective ones that instead of cancelling start resonating... *Shakes computer case to pieces*  :D

If there are defective ones, it's either the retailer or the carriers fault. :P

tbh thats incredible. I would imagine that in the next 3-5 years this will be a proper thing with it not just being for CPU heatsink and fans. Amazing, cant wait for it
