Is the cable plugged in all the way? I've heard this when my power cable was slightly lose.

yes it's plugged all the way. I thought about that too... but seems a random behaviour...it stopped doing it and then during the printing started again and now that the printing is over it stopped again.

Mine makes very strange noises. Keep it away from anything flammable. Maybe put it on something metal.

The power supplies are from meanwell, they take their supplies quite seriously, also on a safety standard. We tried everything to get them "destroyed", nothing worked. We did have 1 bad supply (in about 100) which died from a short-circuit, but it didn't do anything else then that. It just stopped working. (We tested a lot of the UM2 supplies on short circuit protection after that, never managed to destroy one after that single one)

There are 2 possible sources for the noise, one could be bad contact from the cable. Which is no real worry, but could switch off your printer unexpectedly. Another is the fact that it's a switching power supply, those emit frequencies, sometimes you can hear those frequencies.

I can definitely hear those frequencies. For example when the bed heater goes on and off it makes different noises. Strange noises.
