Compact 40 mm cooling fan

The OEM Industries FD0541077S-1N is a 40 mm DC fan designed for tight spaces where a low-profile cooler or chassis exhaust is required. It suits builders assembling small-form-factor systems or replacing a worn unit in existing hardware.

Check connector and voltage

Verify that your motherboard or controller provides a two-pin 5 V header matching the fan’s two-wire lead. The sleeve bearing and 4007 frame size mean the unit fits only mounts drilled for 40 mm fans.

Thermals noise and power

At 6200 RPM the fan produces 29.5 dBA while drawing 0.5 W. The sleeve bearing keeps acoustic output steady during continuous operation, and the low power draw leaves ample headroom on a standard 5 V rail.

Questions about this item

Does the FD0541077S-1N include mounting screws or a power adapter in the box?

The box contains the 40 mm fan with its attached 2-wire lead and 2-pin connector only; mounting hardware and any voltage adapter must be sourced separately.

How do I choose between the 6200 RPM model and a lower-speed variant for my build?

This specific MPN runs at 6200 RPM and 29.5 dBA; if you need quieter operation or different airflow, you would need a different part number with those ratings.

What does the 29.5 dBA rating mean when the fan is installed in a typical case?

At full 6200 RPM speed the fan produces 29.5 dBA; actual noise in your chassis will depend on mounting isolation, case damping and whether you run it at reduced voltage.
