If you have a serpentine belt, pulley is not properly aligned.

or

bearing is worn, but that usually makes a grinding noise.

Actually it could be as simple as belt tension, or a glazed belt (replace), or you may have a bad bearing on one of your pulleys, or (remote) a failing bearing in the alternator.

Good points.

I recently had the water pump, along with all the pulleys, tensioners and belts replaced....amazing how quiet my car idles now.
