Noise cancellation technique harnesses magnets to silence CPU fans [video]

  1. Whether they want to be or not, many PC enthusiasts are well-acclimated to noisy fans; however, some choose quiet operation over impressive overclocking. Of course, that's exactly the problem: quietness traditionally comes at the cost of performance. Noctua's "ANC project"...

    This would be really cool, and hopefully won't come at an outrageous price.

    How come no one has figure out a way to implement Dyson's bladeless fan technology for CPU and card cooling?

    I'm guessing the video should work. Or is it simply my low market share web browser Opera at fault?

    It may be a while before we see it released for general consumption by the public.

    Those fans do have blades they're just in the pedestal. http://electronics.howstuffworks.com/gadgets/home/dyson-bladeless-fan1.htm

    This could be awesome technology, but as the article mentions they'll have to figure out something for the GPU too. Perhaps they can separate the noise cancelling tech from the fan and make a stand alone contraption to put in a PC. maybe in a 5.25in drive bay?

    Not working in chrome either.

    A built-in mic on a fan plus magnets on each blade that use a physically applied magnetic field to counteract noise. Ya, that's probably going to cost a little bit. Look how much more it is (than a stock fan) just to push water around in a case to cool things off.

    I agree with the solution needing to address the GPU as well since those suckers can be annoyingly loud too. My thought would be to have a central/combined cooling unit in the concept more like the power supply -- a single source that addresses the whole. I do understand that requires a pretty big shift in how PCs are currently built.

  11. Dyson's "bladeless" tech does not generate much static pressure like you need to push air through a heat exchangers fins. Might work better for moving air through a low restriction design case.

    I hope this is cheap enough.

    You mean something like a radiator? This would be nice for your radiator fans.

    Hello? This is Noctua .... it'll cost no less than $80
     
  15. They have a speaker to make that loud sound... then they turn it off and everyone is like wow...

    Great I take two noise dampeners for ridiculously noisy MSI TF 7950.

    Seems like a great idea.

    Nice news! Hopefully this can be designed into other fans, GPU coolers included.

    You burst my bubble... I always thought they worked on some kind of "ion thruster" technology.

    Solid state fans (yes google it) is a fan with NO moving parts first revealed like 5 years ago I would like to see these in production let alone focusing development on current tech.

    That is rather awesome, I also hope it doesn't come with too high a price.

    I hope they come out with a kit for radiator fans.

    The fanless technology isn't entirely true... There is a fan at the base of the big round thing and this pumps air around the circle which travels through vents on a certain side. This creates a 'pull effect', making more air go through the loop. :)

    *edit, sorry this has already been said
