Industrial controlled fan for facility cooling

The SXDOOL NMB 4710NL-05W-B50 is a 24V 0.31A 12025 12CM case fan designed for continuous airflow in facilities such as pc case, laptop, server, inverter, power supply, ups, communication equipments and lighting systems. It targets engineers and integrators who need a reliable two-line converter fan for industrial or AV cooling applications.

Replaces basic axial fans lacking speed regulation

This model upgrades from simple fixed-speed fans by adding a controlled two-line interface that allows external speed management. The jump is worth it when a build requires precise airflow tuning or monitoring rather than constant full-speed operation.

Maintains steady airflow under sustained load

The industrial-grade motor and controlled drive circuit deliver consistent rotational speed during prolonged duty cycles in servers, inverters or UPS units. Thermal performance remains stable without the speed droop common in consumer-grade fans under continuous operation.

Questions about this item

Will the 12025 frame fit a standard 12 cm fan mount in my PC case?

The 12025 designation means a 12 cm square frame that is 25 mm thick, matching the common 12 cm mounting holes used in PC cases, servers and power supplies.

How do I connect the two-wire converter to a 24 V supply without damaging the fan?

Connect the red lead to 24 V positive and the black lead to ground; the built-in converter handles the 0.31 A draw, so no external resistor or PWM signal is required.

When should I expect to replace the fan in a continuously running server?

NMB rates the bearing life at 50 000 hours; plan replacement once continuous running time approaches that figure.
