    how does it contact the non spining surface attached to the cpu

    It is described in the PDF provided. However, can someone explained it in a simpler way?

    If they are not connected physically, how does the heat spread to the upper plate for dissipation?

    If they are, then wouldn't the touch surface create heat and spark due to friction and stuff like that?

    Hah, hilarious marketing speech.

    That is the case with human skin, but not with metal coolers...

    Well air is a heat conductor, just not a very good one, i guess if the gap thin enough it won't be an issue, the heat would radiate off the plate, though the 0.03mm air gap into the impeller.

    IE if you place a cool block of metal very close to a warm block, but not actually touching, the cooler block would warm up, and the warmer block would cool down.

    Though i'd really like to see some real world comparisons against some stock and name brand heatsink/fan combos. Even if it's only as good as stock cooling, it's still worth it.

    Air is an insulator, not a conductor. That is why they put mineral wool into walls of buildings.

    But if the tests turn out that this thing is amazing, then I am one of the firsts to adapt to this!

    (Though I still wonder, can you imagine the stress this will place on your motherboard/gpu A spinning metal thing, I hope it won't tear apart the whole system.

    This, is a solution looking for a problem.

    Any gas blowing over a surface _WILL_ follow that surface (Coanda effect). Besides, the problem they are describing doesn't apply to our radiators (neither for heatpipes nor liquid). It doesn't apply to radial fans blowing parallel to the fins. It only applies to axial fans blowing ONTO a sink (think the stock intel cooler) where there MIGHT be sufficient pressure building up from the center of the sink to stop the air flow. Add just a little turbulence (such as the dents in the trailing edge of the noctua fans), and that pressure field becomes unstable and collapses, and the problem is gone.

    Since we're dealing with air that flows at less than Mach 0.3, we can mostly ignore compressibility of air, and see the pressure field as a simple boundary layer. Add variable tip vortexes, and that field is unstable. This is simple Bernoulli. Sheesh, doesn't ANYBODY remember physics from school?

    It isn't fanless, hes using the heatsink as the fan.

    I all for noiseless solutions for cpu cooling that arnt water cooling, I would like to see a review of that thing once it released

    The fact that they're mentioning how if they can't get the cost down then they're not sure how it would be successful means it probably doesn't perform that well and they're trying to make it cheap enough for someone to buy it simply because it's "different".

    Who knows though. Might actually work really well and they're just trying to get it less than say $200 so the enthusiast market would consider it, or less than $10 so the OEMs will consider it.
