Compact 24 V server fan

The SXDOOL u40g24ms6a5-51 is a Nidec 4020 inverter-grade fan built for IPC and server chassis that demand reliable 24 V cooling. Its 40 mm square frame and 20 mm thickness fit tight 1U or blade slots, while the two-pin connector simplifies wiring in power-protection units. The ball-bearing design targets continuous duty in industrial environments.

Sustained 6900 rpm airflow

At a constant 6900 rpm the fan moves a steady stream of air through restricted pathways without the speed drop-off seen in short-burst cooling. The 0.07 A draw keeps 24 V bus loading predictable during prolonged operation, and the 12 cm lead reaches nearby headers without extension cables. Ball bearings maintain consistent acoustic output and rotational stability over extended run times.

Questions about this item

How loud is the 6900rpm Nidec 4020 fan when running continuously?

The unit is described as an IPC mute fan, indicating low acoustic output despite the 6900rpm speed.

Does the 2-pin connector work with a standard 3-pin or 4-pin motherboard header?

The fan uses a 2-pin power connector; it plugs directly into a 2-pin header or requires an adapter for 3-pin or 4-pin sockets.
