120 mm 24 V server fan

The OEM Industries CNDC24B4-991 is a 120 mm square cooling fan with a 38 mm frame depth. It runs on 24 V DC at 0.32 A and draws 7 W. The unit uses a ball-bearing motor and a two-wire power lead measuring 12 cm. No LED lighting is fitted.

Suits 24 V rack and inverter builds.

This cooler targets integrators working with 24 V server, inverter or industrial power systems where a 12038 form-factor fan is specified. Builders using typical desktop motherboards with 12 V three- or four-pin fan headers cannot connect or power this unit without external conversion.

Check voltage, connector

Verify that your chassis or power supply delivers a stable 24 V DC source and that the two-wire lead matches your wiring harness. Confirm the 120 mm square mounting hole spacing aligns with your equipment and that the 38 mm thickness clears adjacent components. Ensure ball-bearing acoustics meet your noise requirements.

Questions about this item

What power source must I already have to run the 24V 0.32A 7W fan?

You need a 24 V DC supply capable of at least 0.32 A to power the two-wire 12 cm lead.

Will the 12038 120*38 mm frame fit the same mounting holes as my existing 120 mm square fan?

Yes, the 120 mm square footprint matches standard 120 mm mounting patterns, so it aligns with the same screw holes.

How can I confirm the ball-bearing fan is spinning correctly after installation?

Listen for smooth, steady rotation and feel consistent airflow from the 120 mm frame; the ball bearing should run quietly without rattling.
