The fan bearings may be worn out or possibly the fan blade is just touching the housing. The shaft of the fan motor normally has some play allowing the shaft to move back and forth along the axis of the shaft. If the shaft slides more than 3/16" check to see that the o-ring is properly in place. You may need to add a few washers to take up the slack.
