Temperature Controlled AC Motor

Hello:

Can anybody point me in the direction where I may find a schematic for a temperature controlled AC fan motor. All the schematics I have benn able to find use a pot to as the means to control the output to the fan. Is there a way of incorporating a thermistor.

I want to use this controller in conjunctiuon with some simple AC fans in a aquarium canopy. When the canopy is at room temperature the fans should slow to a crawl and increase in speed as the temperature rises.

thanks.
