120mm 24V dual-ball bearing fan

The OEM Industries FD241225HB is a 120mm cooling fan built with a dual ball bearing for extended service life. It operates on a 24V supply drawing 0.28A and spins at 2600RPM to deliver 106.1CFM of airflow. The 3-wire connector provides speed monitoring for system management. It suits industrial chassis, server enclosures or custom 24V cooling loops where a compact high-flow fan is required.

Replacing sleeve-bearing or 12V units

Swapping a worn sleeve-bearing fan for this dual-ball model removes the risk of bearing seizure and restores consistent airflow at 44dB. The upgrade is worth it when the existing mount accepts a 12025 frame and the power rail delivers 24V. It does not suit builds limited to 12V headers or those needing PWM speed control via a 4-pin connector.

Limits of 3-wire 24V operation

The 3-wire interface reports RPM but cannot accept a PWM duty-cycle signal, so speed is fixed by voltage. At 24V the fan runs at its rated 2600RPM and 106.1CFM; lowering the voltage reduces flow and may stall the motor below its start-up threshold. Buyers who need variable speed tied to CPU temperature or motherboard fan curves should look for a 4-pin PWM alternative.

Questions about this item

Will the 120mm frame and 12025 mounting holes match my standard 120mm fan slots?

Yes, the 120mm square frame with 12025 hole spacing fits any standard 120mm mounting pattern on cases or radiators.

How do I connect the three wires so the motherboard reads speed correctly?

Plug the 3-wire connector onto a 4-pin PWM header aligning the key; the tach wire (usually yellow) gives RPM feedback while the board supplies 24V power.

When should I expect to replace the 2-ball bearings on this 2600RPM fan?

The dual ball bearings are rated for long life at 2600RPM; plan replacement when noise rises or airflow drops below the 106.1CFM spec.
