kinetic energy cooler

No, the technology works, there's just no fucking reason why anyone would buy one of these.

The spec is 35dB, which is pretty sad compared to cheap 120mm fan coolers.

Quieter than Intel stock coolers on quad cores, but how often do people stress out a quad core when browsing the web? And with the extra cost, I doubt Intel would use it.

And also, the cylinder has to spin at that speed (2000 rpm) or the boundary effect stops working. This means you'll have an annoying on/off/on/off cycle noise, or you'll have to deal with the fan always on.



Sure, they CLAIM it's easy to reduce the motor buzz, but did they fucking do it on their reference design they put in front of press everywherer? fuck no! So it can't be cheap or easy.

This thing looks legit. I cant wait until one spins off, rips through both GPU's and expels the contents out of the case.

If these guys were really trying to market their product, they need to send one to Linus so he can brick another server.
 
And of course the other problem is cost. That free-floating set of fins is soldered to the base, so that piece of metal ain't cheap.

Most of the cheaper heatsinks are extruded, either straight or circular like Intel. Or at most have a second cut at 90 degrees to create more fins with more surface area. Then the next step-up in cost is radiator fins with heatpipes. Soldered fins like that boundary layer cooler is somewhere in-between.
