It sounds mechanical in nature, as if something is turning (alternator?????) or something is trying to work, but can't.
Is it bone stock? Does it have an alarm or remote starter? ANY changes to the underhood wiring? Those are first suspects.

Second the radiator cooling fans as a suspect.

Third, if you have a AIR pump, it might be shorting out and running. Not sure I have read about that happening, but might give you the same noise.

Keep us posted!
