If you get the fans set up to where they push enough air across the surface of the tank, they should cool it down just fine. However, your tank will likely have alot more evaporation. Keep an eye on it and make sure you top off accordingly. Good luck.

find a way to direct the air flow to the surface of the water - no above it or at the lights. this increases evaporative cooling and keeps the tank cooler.
