Well it's hand in hand.

Heat above water = Evaporation.

When I researched on RC, it's generally the removal of the evaporation that cools the water. If there was a sheet of glass above the water to prevent evaporation, and you only removed the heat build up, the water would not cool down.

I would get the electrical and ballasts out of there myself as well.
