Two fans, one each end. 1 pushing air in the other blowing out. my current canopy is set up this way and both previous custom canopies I have done have also been set up this way, cools the lamps and keeps the heat away from the surface of the water. If you don't have the fans yet I do have a spare 4" variable speed ice cap fan, for you I make to be good deal ya.
This is how i have mine setup as well. I have had no problems my canopy is about a year old. I have aqua medic fans and they have stayed quiet since the install and i have seen no signs of them rusting or salt creep.
It's about flow... if you push air in or pull air out... how's the air being replaced. The design with 2 matchedfan pushing and pulling is the best idea I think...
Unless this is a canopy for a 10g tank, i can't see these fans doing anything significant enough to actually drop air pressure to the point that evaporation increases and heat transfer decreases.

I sometimes think you have enough equipment to open your own store.
