Bambu Lab Part Cooling Fan for H2D and H2C

The Bambu Lab Part Cooling Fan for H2D and H2C is an original replacement fan designed to rapidly cool freshly extruded filament as it leaves the nozzle.

Located at the base of the toolhead, the fan works together with the dedicated part cooling air duct to direct airflow toward the printed model. Effective layer cooling helps newly deposited filament solidify quickly, improving overhangs, bridges, fine details, and overall dimensional stability.

The FAF013 fan is designed specifically for the H2D and H2C toolhead architecture and is suitable for replacing a damaged, noisy, or non-functioning original part cooling fan.

Key Features

• Original Bambu Lab part cooling fan

• Part number FAF013

• Designed for Bambu Lab H2D and H2C

• Cools freshly extruded filament

• Works together with the dedicated part cooling air duct

• Helps improve bridge and overhang quality

• Supports sharper details and cleaner model geometry

• Includes the required mounting screws

Rapid Layer Cooling

Freshly extruded filament remains soft for a short period after leaving the nozzle.

The part cooling fan provides airflow toward the printed model so each layer can solidify more quickly before additional material is deposited.

Effective cooling can improve:

• Overhangs

• Bridges

• Fine details

• Sharp corners

• Small features

• Surface definition

• Dimensional stability

Works with the Part Cooling Air Duct

The FAF013 fan is designed to operate together with the H2D/H2C part cooling air duct.

The fan generates airflow while the duct directs that airflow toward the required areas around the nozzle and printed model.

Both components need to be correctly installed and unobstructed for proper part cooling performance.

The air duct is a separate component and is not included with this fan unless specifically stated.

Improved Overhang Performance

Overhanging sections of a model have limited support from the layer beneath them.

Rapid cooling helps freshly deposited filament retain its intended position before gravity causes it to sag or deform.

A correctly operating part cooling fan can therefore significantly improve the appearance and dimensional accuracy of overhanging features.

Better Bridge Printing

During bridge printing, filament is extruded across an unsupported gap.

Cooling the filament quickly helps the strand maintain its shape while spanning between supported sections, reducing drooping and improving bridge consistency.

Bridge quality also depends on print speed, extrusion temperature, bridge flow, filament type, and bridge length.

Better Fine Details

Small features can accumulate heat because the nozzle repeatedly returns to the same area within a short period.

Part cooling helps remove this excess heat and gives each layer more time to solidify.

This is particularly useful for:

• Fine lettering

• Small towers

• Thin walls

• Miniatures

• Sharp tips

• Decorative models

• Detailed prototypes

Important for PLA and Similar Materials

PLA and many similar materials benefit from strong part cooling because rapid solidification helps maintain model geometry.

Other materials may require reduced or carefully controlled cooling, so the appropriate filament profile should always be used.

Part cooling requirements depend on:

• Filament material

• Nozzle temperature

• Layer time

• Print speed

• Model geometry

• Chamber conditions

Designed for H2D and H2C

The FAF013 fan is designed around the Bambu Lab H2D/H2C toolhead.

Its mounting arrangement, electrical connection, physical dimensions, and airflow configuration are intended for these machines.

Fans from H2S, A1 Series, A2L, P2S, X2D, or other Bambu Lab printer families should not be assumed to be interchangeable.

Part Cooling Fan vs Hotend Cooling Fan

The H2D and H2C use separate fans for different cooling functions.

Part Cooling Fan – FAF013

• Cools the printed model

• Helps freshly extruded layers solidify

• Improves bridges and overhangs

• Works with the part cooling air duct

Hotend Cooling Fan – FAF014

• Cools the hotend

• Helps prevent heat creep

• Keeps filament from softening prematurely

• Supports reliable filament feeding

These fans perform different functions and are separate replacement components.

Useful Replacement Part

Replacement may be appropriate if the original fan develops symptoms such as:

• Fan not spinning

• Reduced airflow

• Rattling or grinding noise

• Intermittent operation

• Damaged fan blades

• Damaged cable or connector

• Poor overhang performance

• Poor bridge quality despite correct slicer settings

Installing the correct FAF013 replacement fan helps restore normal part cooling performance.

Package Includes

• 1 × Bambu Lab Part Cooling Fan

• 2 × BT2.6-8 Screws

• 2 × BT3-20 Screws

Installation Note

Switch off the printer and disconnect it from power before replacing the fan.

During installation:

• Remove the required toolhead covers

• Disconnect the original fan carefully

• Avoid pulling directly on the wires

• Install the replacement fan in the correct orientation

• Confirm that the air duct is correctly positioned

• Secure the fan using the supplied screws

• Route the cable correctly

• Ensure the fan blades rotate freely

• Confirm normal fan operation after reassembly

Troubleshooting Note

Poor model cooling does not always indicate a failed fan.

Similar symptoms may also result from:

• Incorrect slicer fan settings

• Excessive nozzle temperature

• Printing too quickly

• Blocked or damaged air duct

• Incorrect bridge settings

• Unsuitable filament profile

• Toolhead wiring problems

Check both the fan and airflow path before replacing components.

Usage Note

This product includes the H2D/H2C part cooling fan and mounting screws only. The separate part cooling air duct, hotend cooling fan, hotend, extruder, toolhead board, and other toolhead components are not included unless separately specified.
