The standard answer for wine storage is cool, dark, humid, vibration
free. I guess different fridges vibrate differently. It's your wine
& your choice. Observe closely when turning on & off, not when just
when running.

I have never seen one of the proper wine fridges when it is operating.
Wonder how much vibration there is there. After all, there's gotta be
a motor of some sort, doesn't there.
