I recently notice that my 3x3x6 tent is getting warm, about 80-85 with lights on. I want to help expel heat and bring in fresh air so I bought a 4" duct fan to run with lights on. It says 80 max cfm. And 65 free air cfm. Will this be enough since I have 54 cubic feet (3x3x6). Also is it strong enough for a carbon filter or should i take it back for a 6" fan at 160cfm?
