Compact 40 mm server fan

The OEM Industries D43M24-02A is a 40 mm DC brushless fan designed for 24 V server and inverter cooling. It suits integrators who need a slim 13 mm profile for tight chassis airflow.

Low current thermal performance

At 24 V the fan draws only 50 mA, keeping power demand minimal in continuous operation. The brushless motor runs without LED lighting, reducing electrical noise in dense rack environments.

Three-pin integration ready

A standard three-pin power connector allows direct connection to server fan headers or compatible controllers. No extra brackets or software are included, so installers must supply their own mounting hardware.

Questions about this item

How do I install the 40 mm fan and which step is often missed?

Mount the 40×40×13 mm frame with four screws, plug the 3-pin connector into a 24 V header, then confirm the fan spins — the step often skipped is verifying rotation before closing the case.

What maintenance will the brushless fan need later?

The 24 V 50 mA brushless motor has no brushes to replace; only periodic dust removal from the blades and housing is required to maintain airflow.

What limit appears first during continuous operation?

The 50 mA current draw at 24 V sets the thermal ceiling; if the power header cannot sustain that load the fan will slow or stop before any mechanical wear occurs.
