Fan Bracket for Lenovo M920 w/ Speed Controller

This custom rear fan bracket replaces the PCIe blanking plate on Lenovo ThinkCentre M920/M720 systems. It mounts a 35 mm fan and a fan speed controller to direct airflow towards NVMe and SATA drives—ideal for builds using the PCIe NVMe riser.

The fan is attached with two M3×8 screws, while the controller is glued to the bracket (the supply connector can be desoldered for a cleaner fit). The complete assembly mounts to the chassis using the original screws from the PCIe cover plate. An M3 threaded insert is required for the side hole.

• Replaces: PCIe slot cover
• Mounts: 35 mm fan + speed controller
• Controller connection: Powered from PCIe riser
• Fastening: Original chassis screws, plus M3×8 fan screws and threaded insert
