  • Four-wire PWM enables precise speed control
  • 120 × 120 × 38 mm fits standard mounts
  • Measured 0.36 A draw at 4000 RPM

48 V industrial 120 mm case fan

This 120 x 120 x 38 mm axial fan runs on 48 V DC and draws 0.54 A for 25.9 W rated power. It is built for servers, telecom chassis and industrial enclosures that already provide a 48 V bus.

Four-wire PWM installation

Red and black wires carry power, blue reports speed and yellow accepts PWM control. The measured current at speed is 0.36 A, so the fan spins at 4000 revolutions every two minutes when the PWM duty cycle calls for full speed.

25.9 W cooling capacity

At full PWM duty the fan delivers its rated airflow for dense component stacks or hot-swap drive bays. Headroom ends when the chassis impedance exceeds the pressure curve or when the 48 V rail cannot supply the 0.54 A start-up surge.

Questions about this item

How do I confirm the fan is running at the intended 4000 RPM after installation?

Monitor the RPM through the motherboard BIOS or fan-control software; the yellow PWM wire reports speed so the reading should settle around 4000 RPM under load.

What accessories are included and what must I source separately?

The fan ships with its four-wire lead (red positive, black negative, blue speed signal, yellow PWM); mounting screws and any 48 V power adapter are not included.

Which capacity matches a 48 V rail drawing 0.54 A?

This model is rated 48 V, 0.54 A (25.9 W); the measured draw is 0.36 A at 4000 RPM, so choose this version when your 48 V supply can deliver at least 0.54 A.
