Guys, it's not about the water temp. What is your AMBIENT temperature (temperature in the room) If your room temp is 70-72 I don't see a problem, however, in the case of this thread the tank temp has to be possibly 5-10 degrees lower than AMBIENT.

Its the transfer of latent energy; the water loses energy/heat when water changes form to a vapor. 2400J/gram H2O at 0C. When the water condenses elsewhere that energy is released again. That's why evaporation cools, and rain warms ^_~.

Plants evapotranspire to control temp, people sweat

The hanging gardens of babylon were the first AC units, utilizing the cooling effects of plants along with irrigation. booya!
