Yes I know that but a sealed whirring fan in a case with dampeners is much nicer on the hearing then listening to the rumble I hear everyday I sit at my computer!
The complex idea is to situate one of these and drive the wind through the entire desktop box using just one fan. Thus reducing the whirring noise to almost nil. More pieces to be fitted to each internal realm of desktop computer but in the end less noise. The PS would also be able to have its fan shut off if used in this format for cooling.
Dyson could not make the blade-less fan work to his liking, I am talking about Lifters .
