News - Noctua demo a CPU cooler with active noise cancellation

[HEXUS]

Prototype technology was developed in partnership with RotoSub.

Pretty clever. That said, I'm very satisfied with the noise level that my D14 produces. In which case wouldn't this tech be better employed on coolers that use smaller/faster-running fans. Like, for example, the HTPC-compatible ones that Noctua make?

It looks like a smart solution. And expensive too.

Smart idea but is it really needed, by far and large the only thing i can hear in my case is the GPU, CPU/Case Fans don't make a whisper compared to it. Might be good if they sell the tech on to GPU makers.

It would be really good if they could fit all this into a standard 120mm or 140mm fan housing. That way you could the fans just about anywhere and still benefit.

I'd love to have this in my water cooling system. It's not that noisy, and it cools really well, but adding these fans to it would be great!

I think I know what you're getting at - replace those 200mm+ fans that are used for case cooling with something a little more "petite" so you can get the same cooling & noise in a smaller case.

That said, what I'd want is that tech used on the sub-100mm fans. Especially the one that the old fella's got in his Shuttle PC. That 80mm one whines like a bored 5 year old on a rainy bank holiday.

Biggest problem I've got at the moment (with my HAF932 rig) is that one of the 120mil's has developed a intermittent rattle, smack it and the rattle goes away for a while. And the rig is so quiet that this is VERY noticable. Got to wonder if I've got a worn bearing - the fan concerned is the case exhaust for the cpu cooler so it's well used.

Both my current GPU (Radeon 7990) and the previous one (Geforce 460SOC) were pretty quiet - fan speeds have/had to exceed 50% of max to make a noticable noise and it was only at 60-75%+ that I'd call it noisy (as in "hoover like").

It's cool but a bit gimmicky at the same time. It's quite niche, when I use my PC I don't normally even notice the fan noise, especially if I am gaming, watching movies or using a headset.

Interesting. More interested what it sounds like when the RPM are reduced a bit - in the demo there is still a lot of air movement noise.

Quiet and cooler temp,. great prototype anyway..

What you have to also realise is that it is cancelling out the vibrations (which cause the noise in the first place) caused by the fan, which in turn can make your PC feel like a washing machine if you have a lot of them. So this would be good for stopping sympathy vibrations too that can have adverse affects on things.
