Description

A dedicated airflow splitting manifold engineered to channel output from a standard 120mm cooling fan into twin 60mm cylindrical ducts. The system features an aerodynamic internal Y-wedge to evenly distribute incoming air left and right, ensuring minimal turbulence and balanced static pressure.

Design Features

  • Modular 3-Piece Build: Prints as an independent center distributor and two identical 190mm slip-fit extension arms.
  • Integrated Venting: Each 60mm diameter arm includes three evenly spaced 12mm exhaust ports along its lower centerline.
  • Exact Fitments: The center unit handles a standard 120mm case fan, complete with correctly spaced mounting points, while robust male collars provide tight, removable connections to the extension ducts. Total assembled span reaches precisely 500mm.
