24 V 5015 hotend fan for Bambu Lab A1

This 24 V DC cooling fan measures 50x50x15 mm and fits the extruder hotend on Bambu Lab A1 and A1 Mini printers. It draws 0.22 A at 5.2 W and spins at 9000 ± 10 % RPM to deliver 4.85 CFM of airflow. The dual ball bearing design aims to reduce friction and noise while extending service life. It ships with a cable lead for direct connection.

Replaces worn or noisy stock hotend fans

If the original fan develops bearing rattle, reduced airflow or fails completely, this unit restores the intended cooling performance for the hotend. The jump is worth it when print quality suffers from heat creep or when the printer reports a fan-speed error. It is not a drop-in upgrade for printers that use a different voltage, frame size or connector pinout.

Simple two-wire swap with polarity care

Installation involves unplugging the old fan, matching the red and black leads to the board header and securing the 5015 frame with the existing screws. The most common issue is reversed polarity, which will prevent the fan from spinning and may damage the controller. Verify the connector orientation before powering on and ensure the fan sits flush so the duct seals properly.

Questions about this item

Will the 50 × 50 × 15 mm frame fit the stock hotend duct on my Bambu Lab A1?

Yes — the fan is built to the 5015 form factor (50 mm square, 15 mm thick) that the A1 and A1 Mini use for the extruder hotend, so it slots into the original duct without modification.

Which way does the 24 V cable plug into the A1’s tool-head board, and what is the polarity?

The lead terminates in the same 2-pin JST-PH connector the printer expects; red wire is positive, black is negative — match the silk-screen on the board and press straight in until the latch clicks.

How often should I clean or replace the dual-ball-bearing fan running at 9000 RPM?

Blow dust out of the blades every few hundred print hours; the dual ball bearings are rated for long life, but plan on a swap once airflow drops below the 4.85 CFM spec or bearing noise becomes audible.
