Could it possibly be that the fan is noisy from sitting dormant, and always did run but much quieter before ?

Just a recollection from a previous experience, ::)

Yes, if it's a cooling fan for the drives, it will run the whole time to keep things cool and/or to exhaust any heat from the control box.

That is what has me puzzeled. It will run all the time. I am afraid it will burn the motor up. I have to keep it unplugged. Thank You !

If the control box is on, it would make sense that the fan is on. When you turn the contol off, the fan should turn off. It's meant to work that way.
