Cooling Fan for Hotend – H2 Series is an original replacement fan designed to cool the hotend in Bambu Lab H2 Series 3D printers. The fan is located between the TH board and the extruder, where it provides targeted heat dissipation from the hotend heatsink.
Properly functioning cooling helps maintain the required thermal transition between the heated and cold sections of the hotend. This limits premature filament softening, the formation of heat creep, and subsequent nozzle clogging.
A worn or damaged fan can cause unusual noise, fluctuating speed, insufficient cooling, or printer error messages. Timely replacement helps restore reliable hotend operation and reduce the risk of print interruptions.
The product is available in variants with different designs and mounting accessories:
| Variant | Compatible printers |
|---|---|
| H2D / H2C | Bambu Lab H2D and H2C |
| H2S | Bambu Lab H2S and H2S Laser |
Before ordering, select the variant corresponding to your specific printer model. The H2D/H2C and H2S variants are not interchangeable without verifying the correct design.
Before replacement, allow the printer and hotend to cool completely and disconnect the device from the power supply. During installation, pay attention to cable routing, fan orientation, and proper connector connection. For the H2S variant with the older FAH047 designation, the fan orientation must be checked before installation; the revised FAH047-V1 variant is ready for direct installation.
