Desk Fan Shroud with Venturi Effect Design

This is a desk fan shroud design that attempts to emulate the new prototype desk fan design by noctua seen at Computex 2018. This design makes use of the Venturi effect to pull in air from the surrounding area to increase the air flow in one direction. This also helps make the air coming out of the fan more directed and increase the fan's efficiency.

This model fits 120mm fans and is perfect for use with USB powered computer case fans. The model can be scaled down or up to fit other fan sizes
