What is the load that this dimmer controls, I had this preoblem in the past, noise and heating. putting a much higher level dimmer, I mean instaed of 250W, I put 400W, this solved my problem and I am sure it will do yours as well.
Of course if the load (the total watts) of the lights is, lets say 400W, I would go for 500 if it exists or even higher if 500 does not exist.
