UltiMaker Fan Bracket Assembly (UM2, 2+C) 80-137633

Replacement fan bracket assembly for UltiMaker 2 and 2+ series

The fan bracket assembly is a critical cooling component located at the base of the print head. This unit houses the dual 12V radial fans responsible for "part cooling"—the process of rapidly lowering the temperature of the extruded filament as it leaves the nozzle. Proper cooling is essential for achieving sharp overhangs, bridging long gaps, and maintaining the dimensional accuracy of fine details. By using this integrated assembly, you ensure that the airflow is directed precisely at the tip of the nozzle from both sides, preventing heat from warping the part during the build.

Over time, these fans can accumulate filament "angel hair" or dust, leading to bearing noise, reduced RPM, or complete failure. Since the fan speed is PWM-controlled and tailored to specific material profiles, a failing fan can lead to poor surface finishes or "stringing." Replacing the entire bracket assembly ensures your cooling system is restored to its original factory efficiency with a simple, bolt-on installation.

What is in the pack?

• 1x Metal fan bracket: A precision-folded stainless steel housing designed to hold the fans at the correct angle relative to the nozzle.
• 2x 12V Cooling fans: High-quality PWM-controlled radial fans with pre-terminated connectors for a direct link to the print head PCB.

Compatibility:

This assembly is designed for the following 12V print head systems:

• UltiMaker 2+ Connect
• UltiMaker 2+ and 2+ Extended
• UltiMaker 2 and 2 Extended
