Description
The Bambu Lab Auxiliary Part Cooling Fan is a dedicated secondary fan upgrade that improves the cooling performance of printed parts by increasing airflow directly over freshly extruded filament. Designed for H2D, H2D Pro, and H2S printers, this auxiliary fan works in tandem with the main cooling system to quickly solidify prints, reduce stringing, and enhance surface finish on bridges, overhangs, and detailed features.
Built to OEM standards for reliable operation, it’s easy to install and helps deliver sharper, cleaner results, especially on prints requiring rapid thermal control.
