I've been having some issues keeping my tank cool, was considering buying a chiller, but have found that a cheap desk fan will cool my tank from 81 down to 78 in about 3 hours, and should be more than sufficient for my needs. The tank is 45 gallons. However, if I leave the fan on, I have evaporation issues, and the heater (100w) struggles to keep up. What would be the cheapest way to have the fan rigged so that if the temperature in the tank hits 80 degrees, the fan kicks on?
