Compact 40 × 28 mm server fan

The Zyvpee PMD1204PQBX-A is a 12 V DC case fan built for tight server and switch chassis. Its 40 mm frame and 28 mm depth suit 1 U racks and small-form-factor appliances where airflow must fit a narrow slot. Ball-bearing construction targets continuous duty in always-on environments.

8.0 W power draw defines thermal headroom

At 8.0 W the fan moves enough air for typical CPU cooler or switch ASIC loads in a 4028 footprint. It will not satisfy high-density GPU trays or multi-core server CPUs that demand greater static pressure. Installers should verify the chassis airflow curve matches this single-fan specification.

Three-pin connector is the integration gate

The 3-pin header delivers power and tachometer feedback without PWM control. Boards lacking a 3-pin fan header or requiring 4-pin PWM regulation cannot use this unit directly. Buyers needing variable-speed control or a different connector must select another model.

Questions about this item

Will the 40 mm × 28 mm frame fit the same mounting holes as my existing 40 mm server fans?

Yes, the 40 mm square frame matches standard 40 mm mounting spacing, so it aligns with the holes used by typical 40 mm server or switch fans.

How can I confirm the ball-bearing motor is running correctly after installation?

Listen for smooth, steady rotation without rattling; the 3-pin connector lets the motherboard report RPM in BIOS or monitoring software so you can verify speed.

Does the package include mounting screws or a 3-pin to 4-pin adapter, or must I buy them separately?

The fan ships with only the 3-pin connector attached; mounting screws and any PWM adapters are not included and must be sourced separately.
