48 V 120 mm ball-bearing case fan

The Zyvpee PMD4812PMB1-A is a 120 mm by 38 mm case fan built for 48 V DC systems. It draws 14.9 W through a 4-pin connector and uses a ball bearing for continuous operation. The black, non-LED frame suits industrial or server chassis that require steady airflow. Buyers needing a 12 V or 5 V fan cannot use this model.

Four-pin PWM control at 48 V only

The 4-pin connector enables PWM speed regulation, but the fan is rated exclusively for a 48 V supply. Connecting it to a standard 12 V motherboard header will not work and may damage the motor. No adapter or voltage converter is included, so the host system must provide a native 48 V rail. Builders without a 48 V power source must choose a different fan.

Simple screw mount, verify voltage first

The 120 mm square frame fits standard case mounting holes using four screws. Installation is straightforward if the chassis already delivers 48 V to the fan header. The most common error is wiring the fan to a 12 V header, which leaves the fan inert or causes electrical stress. Confirm the system pin-out and voltage before fitting.

Questions about this item

Which version of this 120 mm × 38 mm fan should I choose for a 48 V system?

The PMD4812PMB1-A is the only version listed; it is built for 48 V DC input and draws 14.9 W.

What does the 14.9 W rating mean once the fan is installed in my chassis?

At 48 V the fan consumes 14.9 W, so your 48 V rail must deliver enough current for that load continuously.

How does the 4‑pin connector affect speed control with this fan?

The 4‑pin PWM connector lets the motherboard or fan controller vary the speed precisely while the fan runs on 48 V power.
