The light kit on the fan is loose and needs to be resecured using a screwdriver. Sometimes fans hum because of the mechanisms that control their speeds.
Sometimes a humming ceiling fan simply has a bad part inside. Ac motor fans use electromagnets which can cause a distinct humming sound and hotter operation means more wear and tear on bearings. One of the common reasons a ceiling fan makes an electrical humming noise is that the voltage the motor is receiving is too low. Fan blade wind noise is affected by the shape of the blades.
