......would i need to run 10-15 120mm case fans in my aquarium canopy i am building??
:crazyr:

plan so far is to have (2 or 3) on each end blowing inward across the lights, (6) on the back blowing inward on a 45-degree downward angle onto the water & maybe (3) on the front part of the lid blowing outward. there will be a 3/8" gap all around the bottom for additional air circulation
