Bambu Lab Hotend Cooling Fan for P2S – FAF021

Original hotend cooling fan designed specifically for the Bambu Lab P2S 3D printer. This small but essential part ensures stable thermal conditions of the hotend, reliable heat dissipation and thereby significantly reduces the risk of nozzle clogging or filament degradation during long and demanding prints.

The fan is located between the TH board and the extruder and continuously blows over the heatbreak and hotend heatsink. A properly functioning hotend fan is a necessary condition for safe printing from materials such as PLA, PETG, ABS/ASA, PPA, PC and composite filaments.

Main features

• Original Bambu Lab spare part for model P2S (part number FAF021)
• Direct replacement for the original hotend fan – full compatibility and reliability
• Positioned between the TH board and the extruder for efficient cooling of the hotend body
• Helps prevent premature softening of filament and clogs
• Recommended part when errors such as “hotend cooling fan speed is abnormal” occur or when hotend temperature fluctuates
• Compact design, low weight, quiet operation
• Designed for long-term operation and high temperatures in the enclosed P2S chamber

Use and installation

• Suitable as a preventive spare part – having a ready fan in stock minimizes printer downtime
• Recommended replacement when:
  • there is a noticeable change in fan sound (buzzing, grinding, rattling)
  • prints are randomly stopped with a hotend fan error
  • hotend temperature stability worsens or clogs become more frequent
• Installation takes place in the P2S hotend module area – we recommend following the official Bambu Lab manual and completely powering off and unplugging the printer before any intervention.

Tip: When replacing the fan, carefully check and firmly insert the connectors into the TH board. An improperly seated connector is a very common cause of “fan speed is abnormal” errors.

Why keep a hotend fan in stock

On modern Bambu Lab printers, the hotend fan is considered a consumable part. During intensive printing from higher-temperature materials (ABS, ASA, PPA, PC, technical composites), it is exposed to elevated temperatures for long periods and may lose performance or fail completely after hundreds of hours of operation.

Having a spare FAF021 fan for P2S always at hand means:

• no unnecessary printer downtime
• the ability to replace it immediately at the first signs of wear
• guaranteed stable hotend cooling even during long print jobs

This part is an ideal component of the kit for home users, professional workshops and print farms that rely on long-term stable operation of the Bambu Lab P2S printer.

Key features:

• Original Bambu Lab hotend cooling fan for P2S printer
• Part number FAF021 guarantees proper compatibility with the P2S model
• Located between the TH board and extruder for effective hotend cooling
• Minimizes the risk of premature filament softening and nozzle clogging
• Ideal replacement in case of the “hotend cooling fan speed is abnormal” error or noisy operation
• Low weight, compact design and quiet operation
• Recommended as a spare part to minimize printer downtime
