Hotend fan 2510 – Bambu Lab P1 series

Product description

The replacement hotend fan 2510 for the Bambu Lab P1 series (P1P / P1S / P1) is a key component for reliable cooling of the hotend and ceramic heater. When the nozzle is heated to printing temperature, the fan automatically spins up to high speed and maintains a stable temperature, thus preventing filament from softening in the heatbreak (heat creep) and subsequent nozzle clogging.

The compact size of 25×25×10 mm (2510 format), 5 V power supply and high RPM ensure sufficient airflow at low noise levels. The fan is supplied with a matching connector for Bambu Lab P1 printers and is designed as a direct replacement for the original part without the need to modify the wiring.

Main advantages

• Original specifications for the Bambu Lab P1 series – 2510 size, 5 V, high-speed fan suitable for hotend cooling.
• Reliable cooling of the ceramic heater – helps maintain a stable temperature and prevents overheating.
• Prevents nozzle clogging – proper heatbreak cooling minimizes the risk of heat creep and filament jams.
• Quick and easy replacement – direct replacement for the original fan, no soldering or modifications needed.
• Compact and quiet operation – small 25×25×10 mm form factor with optimized airflow and reasonable noise level.
• Suitable as a spare part in stock – ideal for users who print frequently and want to minimize downtime.

Use

The fan is intended for hotend cooling (not for part cooling / print cooling). It automatically turns on when the nozzle is heated and runs at full power during printing.

Recommended for users who:

• have encountered errors such as “hotend cooling fan speed is abnormal” or irregular fan speed,
• experience elevated hotend temperatures or frequent nozzle clogging,
• operate the printer in more demanding conditions (higher ambient temperature, enclosed chamber) and want to have a spare part ready.

Compatibility

• Bambu Lab P1 series
  • Bambu Lab P1P
  • Bambu Lab P1S

(Intended for the hotend cooling fan, this is not the front part cooling fan.)

Technical parameters

Note: The exact appearance of the connector and the specific fan model may vary slightly depending on the production batch, but it is fully compatible with Bambu Lab P1P/P1S printers in terms of functionality.

Installation and maintenance

• Before replacement, turn off the printer and disconnect the power supply.
• Remove the toolhead cover according to the manufacturer’s instructions.
• Unscrew the original hotend fan and disconnect the connector.
• Connect the new fan to the same connector and screw it into the original position.
• Check that no cable or plastic part is interfering with the fan blades.
• After turning the printer back on, test the fan function by heating up the hotend.

For longer service life we recommend:

• regularly cleaning the area around the hotend from dust and filament residue,
• not blocking the fan while it is running and not handling it during operation,
• not operating the printer in extremely dusty or humid environments.

Key features:
