Good point.
Fans should not be a problem, I can use large and slow turning ones.
But what about the A6 servos? Are they making noise all the time or only when enabled or hot?

Most servo drivers under 1 kw are without fan.

But even 150mm cabinet fans with enough flow through a filter are not silent...

I do not care, because a running CNC is way louder.

You should focus on keeping components cool and not whether or not you can hear a M2 washer hit the floor, just my opinion.

As Uwe stated, when the machine is running you won't hear the fans anyway.

Of course, although the SX4 itself is pretty quiet, gearless belt drive spindle with BLDC motor (that's the reason I bought it). But 99% of the time I am in the workshop the spindle will be off and I don't want a constant whine in the background.
I got a Beelink N100 in the meantime and it is not completely silent, but seems OK (and no high pitched noise from the fan).
Not sure whether I should place it inside the cabinet (which is not optimal for an external USB BOB) or behind the monitor.
