Almost all dimmer switches get warm with loads of 60+ watts. Some new ones are transistorized and there is little heat produced for their load range. If yours seems warmer than normal it could be arcing, listen for a buzz or hum. Is the heat and noise consistent? If not it needs replaced. Some very old dimmer switches had resistors in them and required a heat sink (Aluminum comb) These worked but were unstable and caused many bad situations. If you are not sure take a picture of it to your hardware store, they can identify it.

All dimmer switches hum. The older they get, the louder the hum. If you have compact florescent bulbs in the fixture, this will cause the switch to hum louder.
