I agree w/ bigsby. You have plenty sufficent Airflow out of the room to keep everything cool. The main question here is: Where are you getting your "Fresh" air from? If you have no windows... then I would suggest running your Exhaust into the highest point, eg; ceiling if possible, of the next or current room, and fresh air from the lowest part. As we all know, heat rises. Keep the line "out" as straight as possible.

Hope this helps.
killfrenzi Reviewed by killfrenzi on . best way to ventilate??? I am running 2-600watt SunPulse 3k in 2-8" air-cooled hoods. I have a 8" 720 cfm fan that I will be cooling the lights with. The room size is 10'x13'x7.5' and there are no windows, just a door. The air in the next room is a consistant 62 degrees. My question is this: What is the most affective way to keep this room COOL with ventilation??? Smell is not an issue. Rating: 5
