Hmmm--in my oven there's a low-speed 6" blade type fan that merely serves to keep the air moving. It's a sealed insulated box heated by a single 75W incandescent bulb. With a PID controller, the temperature is very, very stable and you can't hear the thing in operation in most environments. --Chuck
