MOUNTING FANS

[Azilla]

Hi guys im setting up a new 75gal system i bought some MH lights and built a custom hood. I wanted to mount 4 fans in the rear was thinking 1 fan on the left blowing in on fan on the right blowin in and the other 2 in the middle sucking air out?? that soundlike it would cool ok?

2 blowing in should be fine, let the air escape through the middle holes. fans that push out salty air tend to degrade quickly. keep the current aimed over the water, not directly on the bulbs...

as far as I remember...

So you think the ((B)) Config would be best flow.
Also noted the back of my hood isnt solid i have a 4inch gap on the bottom.

wouldnt it be better to have two fans at one end bringin in the air and at the other end bring it out so that the air will flow in one direction which would be more efficient....

i cant do it on the very end due to its against a wall back is the only option.
