Compact 40 mm Server Fan

The Zyvpee DV04028B12U is a 40 mm square case fan with a 28 mm thickness, designed for tight server and workstation chassis. It runs on 12 V DC and draws 0.66 A through a 4-pin connector, providing PWM speed control for targeted airflow in dense builds.

Suited For Specific 4028 Mounts

This unit fits only 40x40x28 mm mounting patterns, so it serves technicians replacing an exact AVC 4028 equivalent or building custom cooling in 1U appliances. It is not for builders who need a different thickness, a larger frame size, or addressable lighting.

4-Pin PWM Connector Decides Fit

The 4-wire header is the single specification that determines compatibility; without a matching 4-pin PWM header on the motherboard or controller the fan cannot be regulated and will not install correctly.

Otázky k tomuto produktu

How can I verify the fan is running correctly after connecting the 4-pin connector?

The 4-pin connector provides a tachometer signal so the motherboard or fan controller can report the real-time RPM in BIOS or monitoring software.

What is included with the DV04028B12U and what must be sourced separately?

The package contains the 40 mm ball-bearing fan with a 4-wire lead; mounting screws, fan filters or a separate fan controller are not included.

Which version of the 4028 series should I choose for a 12 V server chassis?

The DV04028B12U is the 12 V 0.66 A model with a 4-pin PWM connector, designed for 40x40x28 mm server fan mounts.
