The Bambu Lab Auxiliary Part Cooling Fan for X1 Series and P1P is the OEM replacement for the secondary part cooling fan that provides additional directional airflow to freshly extruded filament layers. In combination with the primary toolhead fan, this auxiliary fan improves cooling performance for overhangs, bridges, and small features, helping to prevent drooping and layer deformation during printing.

If the auxiliary cooling fan fails or is blocked, cooling-sensitive features such as steep overhangs and long bridges may show reduced quality. Replacing the fan with this OEM part restores the full dual-fan cooling capability of the X1 Series and P1P toolhead assembly, ensuring optimal layer solidification across a wide range of filament types and geometries.

Key features

• OEM auxiliary part cooling fan for the X1 Series and P1P, providing secondary directed airflow to extruded layers.
• Improves overhang and bridging performance by cooling freshly extruded filament rapidly and evenly.
• Works alongside the primary cooling fan for full dual-fan part cooling capability.
• Restores cooling performance when the original auxiliary fan has failed or become blocked.
• X1 Series and P1P-specific design and connector for a direct OEM toolhead replacement.

Compatible with: Bambu Lab X1, X1C, X1E, P1P
