120mm 38mm 48V PWM Case Fan

The Zyvpee 2B12038B48M P076 is a 120mm by 38mm case fan built for systems that run on a 48V DC supply. It targets builders who need high-voltage cooling in industrial chassis, servers or specialised workstations where standard 12V fans are not compatible.

Ball Bearing 4-Pin PWM Connector

A ball bearing supports the rotor for durable operation under continuous load. The four-pin PWM header allows the motherboard or fan controller to regulate speed precisely, so airflow matches thermal demand without running at full voltage constantly.

Replaces Standard 12V Fans In 48V Environments

This unit upgrades any 120mm 38mm slot that currently uses a lower-voltage fan but is wired for 48V input. The jump is worth it when the power infrastructure is fixed at 48V and a direct-drive PWM fan removes the need for voltage converters or adapter cables.

Questions about this item

Does the 4-pin PWM connector on the 2B12038B48M run at 48 V or does it need a step-down?

The fan is rated for DC 48 V and 0.54 A, so the 4-pin PWM header must supply 48 V; a standard 12 V motherboard header will not power it correctly.

Will the 120 mm by 38 mm frame fit my chassis fan slots?

The housing measures 120 mm square and 38 mm thick; verify your case has 120 mm mounting points with at least 38 mm clearance for the deeper frame.

How do I wire the four leads so PWM control actually works?

Connect the four wires to a 48 V 4-pin PWM header matching the pinout — power, ground, sense and control — otherwise the fan will run at full speed without speed regulation.
