Compact 40 mm server fan

The Zyvpee DB04028B12S P326 is a 12 V DC case fan built for tight server chassis. Its 40 x 28 mm frame fits 1U and blade systems where larger coolers cannot mount. Four-wire PWM control lets the motherboard regulate speed automatically.

Ball-bearing build with four-wire lead

A dual-ball bearing supports continuous high-RPM operation in dense racks. The 5-pin connector carries power, ground, tachometer and PWM signals on a single cable. Black non-LED housing keeps the airflow path clean and unobtrusive.

12 V 0.96 A power draw decides fit

The fan draws 0.96 A at 12 V, so the header or fan controller must supply that current without voltage drop. Builders who need lower current or 5 V operation should choose a different model.

Questions about this item

What does the 4-wire 5-pin connector on this 40×28 mm fan control?

The four wires carry 12 V power, ground, a tachometer signal and a PWM speed-control line; the extra pin is a keyed dummy position that prevents mis-insertion.

How much clearance does the 28 mm thickness need in a 1 U or tight chassis?

The frame is 40 mm square and 28 mm deep, so allow at least 28 mm behind the mounting plane plus room for the 5-pin header and cable bend radius.

How do you connect the 5-pin header without bending pins?

Align the keyed notch on the fan header with the missing pin on the motherboard or backplane socket, press straight down until seated, then route the cable to avoid tension on the connector.
