UltiMaker System Fan Set (S Series) 80-227543

Replacement system cooling fan set for UltiMaker S-series

The system fan set is a vital thermal management component located in the bottom compartment of the UltiMaker S-series printers. These fans are responsible for active air circulation across the mainboard, stepper drivers, and the internal power supply unit. By maintaining a constant flow of cool air, the system prevents the electronics from overheating during long-duration prints, ensuring stable signal processing and consistent power delivery to the heaters and motors.

Over time, these fans can accumulate dust or develop bearing wear, resulting in a noticeable "whirring" or "grinding" noise. If a fan fails completely, the printer may shut down unexpectedly or report thermal errors to protect the sensitive electronic components. Replacing the fans with this complete kit ensures your printer's "brain" remains within its optimal operating temperature range, even in challenging industrial environments.

What is in the kit?

• 2x System fans: High-reliability 24V axial fans with pre-terminated connectors for the S-series mainboard.
• 2x Fan shrouds: Custom-moulded plastic covers that direct the airflow precisely over the heatsinks and power components.
• 8x M3x32 bolts: Extended mounting bolts to secure the fans and shrouds through the chassis.
• 8x Locknuts: Vibration-resistant nuts to ensure the fans remain secure during thousands of hours of printer operation.
