120mm 24V Ball-Bearing Fan

The OEM Industries DATA1238B4U is a 120mm DC cooling fan designed for 24-volt systems. It uses a dual ball-bearing assembly and a three-wire power connector for speed monitoring. The frame measures 120 by 120 by 38 millimetres and draws 0.8 amps. No LED lighting is fitted.

Suits 24V Industrial Builds

This fan fits equipment that runs on a 24-volt DC supply and accepts a standard three-wire header. Builders working with 12-volt PC motherboards or four-wire PWM controllers cannot use it directly. Buyers needing variable speed control via PWM should look elsewhere.

Fan-Only Package

The unit ships as a bare fan without mounting brackets, screws or thermal compound. Installers must supply their own fixation hardware and any required wiring adapters. No software or driver bundle is included.

Questions about this item

What power source must I already have to run the 24V 0.8A fan?

You need a 24V DC supply that can deliver at least 0.8A and a three-wire connector for power, ground and tachometer signal.

Will the 120mm 38mm thick frame fit in the same mounting holes as my existing 120mm fans?

Yes, the 120mm square footprint matches standard 120mm mounting patterns, but verify your chassis has 38mm clearance for the thicker frame.

How can I confirm the ball-bearing fan is spinning at the correct speed after installation?

Connect the third wire to a motherboard or fan controller header and monitor the reported RPM in BIOS or software to verify operation.
