Compact 40 mm Server Fan

The Zyvpee FFB0412UHN-BC2E is a 40 mm square axial cooler built for tight server and workstation chassis. Its 12 V, 1.01 A four-pin connector allows PWM speed control for precise thermal management. The 28 mm thickness fits standard 4028 mounting patterns without modification.

12 V 1.01 A Headroom

At full voltage the fan draws just over one amp, delivering strong airflow for CPU cooler heatsinks in 1 U or blade systems. The dual-ball bearing sustains continuous high-RPM operation where sleeve bearings would wear quickly. Headroom diminishes if the system demands near-silent idle speeds below the PWM floor.

Dual-Ball Bearing Build

The two-ball bearing design resists dust ingress and orientation-related wear, extending service life in dense rack mounts. Four-wire PWM control enables motherboard or fan-controller curves without extra adapters. Black non-LED housing keeps the aesthetic neutral for professional environments.

Questions about this item

Will the 40 mm 4-pin PWM connector on this fan work with the 3-pin headers on my older motherboard?

The 4-pin connector fits a standard 3-pin header; the fan will run at full 12 V speed without PWM control.

How can I confirm the 1.01 A draw is normal once the fan is installed?

Check the motherboard hardware monitor or BIOS fan-speed readout; a steady RPM at 12 V indicates the expected current draw.

Does the box include mounting screws or only the 40x40x28 mm fan unit?

Only the fan with its attached 4-wire lead is supplied; mounting screws must be purchased separately.
