I decided to do a better test since I haven’t been in a quiet room with the Framework Desktop on since I got it. I use the Framework Desktop for work so I turn it on each morning and turn it off each night. When I’m working I’m using headphones, on a meeting, or otherwise hearing sounds from my dogs.
I just turned on the Framework Desktop in my quiet room at night and I hear the noise you all are talking about. I timed it at 7 minutes off (22-25 dB) and 3 minutes on (27-32 dB) for two intervals and the sound is exactly as heard in the recordings people shared. Take the decibel measurements with a slight grain of salt as the machine is next to a window and I’m near a few noisy roads.
It’s not loud enough to bother me normally since I primarily use this machine during the day with headphones and other noise from dogs but I can see how if it were louder in my specific case it would drive me crazy.
