I am using an AIO from Arctic.
CPU is Ryzen 5900x.
Until 50°C the fans are off.
Case fans run on 450 RPM. 
Noise level is quite acceptable, did not measure it though.

Cheers
Moshe

Usually the second part means noisy fans.  Has anyone on the list used a
water cooler system to  move the heat out to a radiator that can be cooled
with larger slow turning fans?  I don't want to invest in a water cooling
system only to find out after I get it that it hums loudly from the water
pump, or the radiator fans aren't actually very quiet, or it makes
gurgling or swooshing noises, etc.
