Mainboard fan (4010) P1/X1

The replacement 4010 mainboard fan is the original type used in Bambu Lab P1 Series and X1 Series 3D printers. It ensures stable cooling of the control (MC) board, thus preventing overheating, error messages, and unexpected restarts during printing.

Main benefits

• Stable operation of the control board – active cooling prevents overheating and shutting down of the printer during long prints.
• Compatibility with P1 and X1 – designed for the Bambu Lab X1 and P1 (P1P/P1S) series as an OEM replacement control board fan.
• Automatic speed control – fan speed is controlled by the firmware as needed; the user does not have to switch it on or adjust it manually.
• Compact 4010 format – the standard size of 40×40×10 mm allows for an exact replacement of the original part without modifications.
• Long service life – designed for continuous operation, with a lifetime of up to tens of thousands of hours at normal temperatures.

Detailed description

The fan is designed primarily for cooling the MC (control) board in the enclosed space of the printer. When the electronics temperature rises, the firmware automatically increases fan speed to maintain safe operating conditions. This ensures reliability at high printing speeds, typical for Bambu Lab printers.

The fan is supplied as a standalone part. Installation usually consists of removing the bottom cover of the printer, replacing the fan with the original piece and reconnecting the connector on the board. It is recommended to follow the official manufacturer’s manual or wiki for the specific printer model.

Warning: Always disconnect the power before any printer maintenance and wait until all parts have cooled down.
