I don't get where all these complaints about noisy fans are coming from unless very early batches had bad fans. Mine were made in April 2020 and the fans are very quiet. They run at 90% intensity and at the peak they kick on high power about every 30 min for 5 minutes or so and you can barely hear it unless you're really listening... sounds just like the a/c is blowing. Here are some dB readings I did a while back:
Here are the decibel readings with 1 x XR30 G5 Blue running (a/c and house fans/filters turned off), max fan speed set to 100%:
