One of the main sources of noise from your bathroom exhaust fan is the ductwork it hooks into. When your fan removes the air from your bathroom, it has to then transport it outside of your house through a vent. The air is carried through the ductwork. No matter what you do, moving air will always create some level of noise.

One possible explanation would be that the fan rotor "lands" in a random place in its 360 degree range of movement each time, so sometimes it lands in a better or worse spot vis-à-vis dust buildup. You could try using a can of compressed air to dislodge built-up dust inside the fan. It might relieve the problem, for a little while.
