Wow. That hum is annoying as all hell. I think that would drive me crazy to have in the garage all the time. Will have to config charging to run at night. Surprised more people aren’t put off by it.
Wait till it's hot enough for the fans to run. I can hear my car(S) charing on the other side of the house when it's hot in the garage.

I'm charging using 120v too for now, and mine hums even after it has reached the 85% Mac Charge Level. Oh, and it is also outside my Preferred Charging Time. Seems like it should be doing nothing and be completely quiet.

Anyone else notice this?
If it's supposed to hit a charge % and you're on 120 it's charging outside the charge time in order to try to hit that % by the end of your window. 120v is 1kW an hour into the pack. Unless it's 'warm'. Which I've noticed my 120v up north randomly even ran the fans when I din't think the pack was even above 90 degrees.
