I believe if your lights are oriented parallel to the front of the tank,
placing a single fan blowing in at one end will have better results.
Such a configuration will create a strong local current around the
lights. Orienting the fan to blow out will remove the same amount of air
from the hood, but not from the same places. In other words, the air
current right around the bulbs would be lower.
