Fans need more surface area to draw air from than their own area. A 140mm fan will not flow as much air pulling it from a 140mm tube as it will pulling it from an open space. Same with exhaust flow. In fact most fans do not blow air in a cylindrical pattern.
Most just scatter the air in all directions. End of video show exhaust pattern.
