120 mm 24 V ball-bearing fan

This OEM Industries 4710NL-05W-B40 is a 120 mm square DC fan rated for 24 V and 0.22 A. It uses a two-pin power connector and a ball bearing for continuous operation. The unit is intended for system builders and technicians who need a direct replacement cooler for industrial or server chassis.

Replaces worn 120 mm 24 V two-pin fans

The jump is worth it when the original cooler develops bearing noise, reduced airflow or complete failure. A ball-bearing design restores reliable rotation at the specified voltage without requiring a connector change. Buyers who need PWM speed control or a three-pin tachometer signal should look elsewhere.

Verify 24 V supply and two-pin header clearance

Confirm that the target device provides a 24 V DC rail and a matching two-pin header before ordering. The 25 mm thickness must fit the available mounting depth in the chassis. No LED lighting or additional wiring is included with this fan-only package.

Questions about this item

What are the exact dimensions of the 4710NL-05W-B40 fan for mounting clearance?

The fan measures 120mm square with a 25mm thickness, so allow that footprint plus cable space when planning the mount.

How do I connect the 2-pin power connector to a 24V source without damaging the fan?

Match the two wires to the 24V supply polarity; the 0.22A draw is low, but reversing the pins will prevent the ball bearing motor from starting.

When should I expect to replace the ball bearing in this 24V fan?

Ball bearings typically run for years at 0.22A load; replace the unit once audible noise or vibration appears, as the bearing is not user-serviceable.
