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.

I would say that is enough for electrical, but others should advise you better here. I might also put it into a plastic box to combat splashing if it is by water, these boxes are available at electrical stores.

I think the two purposes of the fans are seperate, not really hand in hand.

1. Remove the heat before it heats up your water.
2. Increase evaporation by moving air across the surface of the water.

You can use a fan passing cold air across the surface of your water to increase evaporation, it is not tied to the hot air necessarily.
