The Bambu Lab Power Cooling Fan is the OEM replacement for the fan that cools the power supply electronics inside Bambu Lab printers. The power supply generates significant heat during operation, particularly during long print runs, and the cooling fan dissipates this heat to maintain safe operating temperatures for the electronics. Proper cooling is essential for preventing thermal throttling, premature component wear, and unexpected shutdowns.

If the power cooling fan fails or becomes too noisy, the power supply is at risk of overheating, which can cause the printer to thermal-shutdown mid-print or permanently damage the power electronics. This OEM replacement fan restores full cooling airflow to the power supply and electronics bay, ensuring reliable long-duration printing.

Key features

• OEM cooling fan for the power supply electronics, maintaining safe operating temperatures during printing.
• Prevents thermal throttling and unexpected shutdowns caused by insufficient power supply cooling.
• Protects power electronics from heat-related wear and premature failure during long print runs.
• Direct OEM fit for the electronics bay in the relevant Bambu Lab printer models.
• Restores quiet, reliable cooling when the original fan has become noisy or stopped spinning.

Compatible with: Bambu Lab X1E
