woh interesting, I wonder what kind of motor they have to be able to do this, some kind of stepper I'd assume.
I then ask myself how long such a motor would last!

I'm still sceptical it will be silent, I've bought many fans and have to undervolt even the best.
I think the interesting part isn't that it may be silent... but the possibility that you can now run fans at a higher speed with no increase in loudness, increasing cfm/db.Originally Posted by mark22
Would these fans only run at one consistent speed?
This is interesting! I'm might need something like this, as I always sneak out of bed during midnight and play on my PC. Unfortunately, my noisy chassis fans always end up waking up my nephew who's sleeping beside me, ruining my moment, LOL.
Seems like a very interesting invention. Hope it does work and not too dear to buy. Well we'll see when Computex starts. Looking forward to Hexus.TV.
I wonder how much noise cancelling these will be able to cope with. Is it going to pick up ambient noise from other components and attempt to cancel that out as well, or is it just noise from itself so it becomes silent?
I would be really interested in the former, something that can offset the noise of hard drives and CPU coolers would be fantastic for when I build a mini data centre in my study. Might mean I don't have to hid it all in an insulated stud wall cupboard
this is incredible, I will definitely buy this on release - as vdbswong said: better cooling with decreased noise, genius!
“Our performance target is to achieve about 80% more airflow and 120% higher static pressure at the same noise level as the original NF-F12”
That should clear things up a little!
Quick, someone patent the idea for a whole noise-cancelling case, Funkstar's onto a winner!
You're right, it's needed on graphics cards definately, a good case doesn't need that high a fan speed to create good enough airflow.I think the interesting part isn't that it may be silent... but the possibility that you can now run fans at a higher speed with no increase in loudness, increasing cfm/db.
I have 2 pairs of noise-cancelling earphones, and the difference they make is substantial. I'm not sure how these things will compare, since what they attempt to do is different, but there is potential for something good here.
Judging from my experience with this technology, I would say that Vdbswong is likely to be correct. My earphones are never "silent" (in low noise conditions there is a clear hiss coming form them when the noise-cancellation is on) but if there is ambient noise in the room they take a huge chunk out of it, more than any noise-blocking earphone I've ever tried.
The fact that they are going to put the emitter in the fan itself is also a great idea. Separating the 2 sources of sound will create an interference pattern, meaning that you would have to position yourself at exactly the right place to perceive the silence. Move a little bit this way, and suddenly the noise is amplified! Noctua are on to something with this.
Thats a superb idea. Cant believe we all knew the Physics already.
Woooh! Hold on..... I thought noise cancelling fans was intriguing but 'your nephew sleeps beside you'?! WTF is going on there?
Technically they are not silent at all, they are going to generate two noises, one is the sound fo the motor spinning the fan and the other is the cancelling sound and when the two are heard at the same time it's as if you can't hear anything at all.
