i have a 12inch vortex fan cooling 4 1000watt 8inch aircooled lights. what size should i make the intake 6/8/12inch? im cutting the hole in the floor should i make the hole 6inch and reducers to a 12inch to the fan, reduce the 12inch from the fan to a 8inch go threw all lights then back to 6inch for outake, i heard reducing the diameter of hole speeds air flow is this true?
