Compact Server Cooling

The Zyvpee DF04056B12U is a 40x40x56mm square DC cooler designed for CPU cooler compatibility in server and workstation chassis. Its dual ball bearing supports continuous operation in dense thermal environments.

8-Pin Integration

The eight-pin power connector carries 12V at 1.88A, delivering 8 wires for monitoring and control without proprietary headers. This interface frees standard four-pin headers for other chassis fans while providing full speed feedback to the management controller.

Thermals and Acoustics

Dual ball construction reduces bearing wear at high RPM, keeping airflow steady under sustained load. The non-LED black frame minimises visual distraction in rack cabinets while the 12V supply ensures predictable power draw during normal operation.

Questions about this item

How does the 1.88 A current draw affect continuous 12 V operation?

The fan draws 1.88 A at 12 V, so the power source must supply at least that much current without voltage sag during all-day use.

What noise or heat level should I expect from the 2-ball bearing running constantly?

The 2-ball bearing design handles sustained rotation with minimal friction, keeping acoustic output and bearing temperature stable over long periods.

Which motherboard or controller header accepts the 8-pin connector on this 40×40×56 mm unit?

An 8-pin fan header or compatible PWM controller is required; standard 3-pin or 4-pin headers will not mate with this connector.
