I can hardly hear my mac mini or my iMac fans they both have fans that spin slowly

it.



Presumably the reverse must be true.

If they scaled up these better designed iMac fans (although its surprising
Dyson didn't get there first) then presumably they could make much more
efficient wind turbines. With a gentle breeze generating Gigawatts
of power.

So that everybody would be happy.


My laptop is quiet..

until you start using four cores on its i7 processor and the GPU 100%.

then you can hear the whine.
