DD1 squealing sound (bad capacitor?) when powered but OFF

I have a strange problem with my DD1, where if it's plugged in and left OFF for a long time (say, overnight), when I get back to it I can hear a quite loud squealing sound that sounds a lot like capacitor whine. If I turn the wheel ON I can hear it chirp down to silence and it's fine. I can then turn off the wheel and the whine doesn't come back, but I can hear the fan on the power supply to be quite loud. Eventually it dissipates.

Anyone know what's going on here? Seems like quite a strange issue.
