Probably a dumb idea but here it goes: Would it be feasible to switch off the power supply to HDDs inside a computer while said computer is turned off? The HDDs inside my rig are the loudest components. They cause the whole shelf the computer is sitting on to vibrate a bit creating a humming sound that is driving me insane. During a normal workday I do not need the HDDs. My idea is to wire the 5V power supply to a switch on the back of the computer so I can only turn them on when I actually need the storage. The computer is running Windows 10, I'd only turn the switch while the computer is turned off. Just how terrible is this idea?
