Speaking of which, you can do that any time - CONFIG:KPA3 = Fn1 thru Fn4
(set it back to "nor" when you're done).

With everything else quiet (AF gain turned down), I can definitely hear
that the fans are running on Fn2 and up, but it's mostly fast-moving air
I can hear - not whine from the motor or anything. If I had headphones
on, noise coming through the external speaker, or even much other 
ambient noise in the shack (e.g. computer), I don't think I'd notice the
fan noise at all - it's definitely never bothered me in normal
operation.
