A 120 mm by 38 mm ball-bearing fan runs on 24 V at 0.37 A and 9 W with a two-pin connector and no LED lighting
The OEM Industries SCNDM24Z7-912 is a 120 mm square fan designed for 24 V server and inverter environments. Its 38 mm thickness and ball-bearing motor suit rack-mount chassis and industrial power supplies that require high static pressure. The two-pin connector provides simple power delivery without PWM control. Buyers needing variable-speed headers or 12 V operation should look elsewhere.
At the rated 24 V the unit draws 0.37 A for 9 W of input power, moving air through dense heatsink fins in typical server workloads. Ball bearings maintain consistent rotational stability under continuous duty cycles. Acoustic output rises with the higher voltage needed for maximum airflow in restricted spaces. No PWM signal means speed stays constant unless an external controller is added.
The package contains only the bare fan assembly with two flying leads; no mounting screws, filters, adapters or software utilities are included. Integrators must supply their own 24 V source and mechanical fasteners suited to the target chassis. The lack of bundled hardware keeps the bill of materials lean for volume deployments. No RGB lighting or monitoring features are present.

Mount the 120*120*38mm frame using the four corner holes, connect the 2-pin plug to a 24V header, and verify the black and red wire polarity before powering on.
The ball bearing is sealed; periodically clean dust from the blades and frame with compressed air to maintain airflow.
The 9W power draw at 0.37A sets the thermal ceiling; ensure the 24V supply can sustain that current continuously.
