Bambu Lab Hotend Cooling Fan for H2 – FAF014

Original Bambu Lab hotend cooling fan for the H2 toolhead (FAF014). This small but key component is located between the TH board and the extruder and ensures stable cooling of the hotend. This prevents heat creep (gradual heating of the filament too high up in the system), premature softening of the material and subsequent nozzle clogging or print interruption.

It is intended as an official spare part for the H2 series and is fully compatible with:

• Bambu Lab H2D and H2D Laser
• Bambu Lab H2S and H2S Laser

If you print long jobs from ASA, ABS, PETG or technical filaments, having a spare hotend fan on hand is practically a necessity – failure of this part means an immediate stop of the print.

Key features

• Original Bambu Lab part (FAF014) – guaranteed compatibility with the H2 toolhead.
• Specifically designed for hotend cooling – located between the TH board and the extruder for efficient airflow around the heat break.
• Prevents nozzle clogging – reduces overheating of the filament in the area above the nozzle and lowers the risk of material jams.
• Essential for stable high‑temperature printing – especially when printing ASA, ABS, PA, filled technical filaments and when using a heated chamber.
• Quiet and compact – low profile, adapted to the limited space in the H2 toolhead.
• Easy integration – supplied as a ready‑to‑install module for mounting into the H2 head.

Why keep a spare hotend fan in stock

• For high‑temperature prints it is a consumable part – during long‑term printing in a hot chamber the fan is exposed to high thermal stress.
• Fan failure = immediate print stop – the controller reports a hotend fan RPM error and the print is interrupted.
• Downtime prevention – having a spare fan in stock is crucial for users who operate the H2 printer professionally or almost continuously.

Installation recommendations

• Before replacement, turn off the printer and disconnect the power supply.
• Follow the official Bambu Lab Wiki guide for disassembling the H2D/H2S toolhead.
• Be careful with flat cables and connectors, work slowly and systematically.
• After installation, check that the fan rotates freely and does not rub anywhere.

This fan is an ideal choice for anyone who wants to maintain maximum reliability and long‑term operation of the Bambu Lab H2 without unnecessary downtime caused by hotend cooling failures.
