I think you have to be a bit careful to what those noises sound like in reality - in a case
my WF on my 570 (which must be similar to the other WFs) - is silent at idle, and even at 100% fans - really the noise is just air noise - and its not that noisey either
that is to say - its a noise thats not annoying
I've had fans at idle that are more annoying
there is quite a difference in hearing air-rush, vs an annoying ticking noise, or pulsating etc etc
