Qidi X-Pro Dual Vortex Fan Duct

This Dual Vortex Fan Duct minimizes rattling noise while maximizing cooling efficiency.

Why Vortex? The goal is to cool the filament being extruded, not the extruder nozzle. A vortex pattern moves air around the extruder nozzle rather than directly at the nozzle. This ensures the fresh cool air from outside the extrusion area hits the melted filament rather than the extruder nozzle.

How? Air is tunneled through a ring around the extruders. Rather than escaping through openings in the wall
