Hi,
a while ago I created a temperature controller for a friend's aquarium. I took my arduino, added a LCD screen and installed a 1-wire sensor (a straw + some epoxy glue made it waterproof). When done I made it small by using the SMD version od atmega168.

The basic principle is to blow air to the watter surface to cool it down due to evaporation. The computer fan provides the air flow and my black box controlls it so it spins faster as the temperature rises (to reduce the noise, so it doesn't just turn on and off but has PWM controll).
