If it is dusty, blow it out with a can of compressed air. Disconnect the power lead from the board first, and/or do not allow the fan to spin while you blow it out.

Is it old? It may have be unbalanced due to wear.

If it is simply noisy due to spinning up to maximum revs from heat, make sure your system is well ventilated - no obstructions around the case, good airflow, away from other sources of heat. Make sure the case fans are working properly. Make sure there is no dust build up inside the case.

Otherwise, not much you can do but get a better CPU fan.

You can always replace the Fan & Heat Sink with a new one. It's a very simple and unless you go completely overboard a cheap thing to do. ;)
