120 mm blower fan runs on 24 V at .3 A with four-wire PWM control and ball-bearing reliability
This OEM Industries D12F-24PLMC11J is a 120 mm blower-style fan built around a NIDEC 12032 motor. It runs on 24 V at 0.3 A and uses a four-wire connection for speed control and monitoring. The black frame houses a ball bearing for durable rotation.
The blower design pushes air through a concentrated path, making it useful for heatsinks or enclosures that need focused cooling. Builders who need wide-area case ventilation or silent operation at low RPM should look elsewhere, as this unit is optimised for static pressure rather than broad airflow.
At the rated 24 V and 0.3 A the fan delivers its specified pressure and speed for targeted cooling jobs. Headroom exists for PWM speed reduction when full output is not required. Running the motor above 24 V or on a supply that cannot sustain 0.3 A will exceed the design limits.

The fan is rated for a 24V power source and draws 0.3A through its four-wire connector.
It shares the 120mm frame size but uses a blower housing instead of an axial design, so the screw pattern may match while the airflow direction and clearance needs differ.
The fan should report a speed signal back to the motherboard or controller and vary its RPM in response to the PWM duty cycle sent on the fourth wire.
