frostedwonder Reviewed by frostedwonder on . ventilation/fan question i understand stacking case fans isnt the best method. i was wondering if i built a air proof box with 2 case fans ( one on each side) and both blowing in the same direction with a piece of square to round duct connected to the box. the square end covering one of the fans screwed into the box and the round end connected to carbon filter. would it keep the all available cfm's ?
