One place that could do that is the generator and fan. Busted generator bearings or fan rubbing the shroud. Troubleshoot by taking off the=20 fan belt and rotating the generator by hand (engine off ofcourse). = Rubbing fan would propably give you an uneven grind once or twice at each = revolution and generator bearing will probably have a constant noise.
If this fails, at least you have ruled out the generator/fan = possibility.
