Compact server cooling fan

The Zyvpee PMD1204PQBX-A is a 40 mm by 28 mm case fan built for tight server and switch chassis. It targets system integrators who need directed airflow over a CPU cooler in a 1U or blade form factor. The four-pin connector enables PWM speed control from a standard motherboard header. Non-LED black housing keeps the visual profile neutral for rack environments.

Ball-bearing thermals and power

A ball bearing supports continuous high-speed rotation in dense enclosures where sleeve bearings wear quickly. The motor draws 8.0 W at 12 V, delivering strong static pressure for restrictive heatsink fins. PWM control lets the fan spin down during light loads, reducing acoustic output when full flow is not required. Four-wire feedback gives the host real-time RPM data for thermal management.

Four-pin PWM control requirement

This fan requires a four-pin PWM header to regulate speed automatically; a three-pin header will run it at fixed maximum voltage. Buyers whose boards only offer three-pin voltage control cannot use the speed-curve features. The 40 mm by 28 mm frame also limits use to coolers and brackets designed for that exact footprint.

Questions about this item

How do I mount the 40mm by 28mm fan and connect the 4-pin plug?

Align the four corner holes with the chassis or CPU cooler brackets, secure with the supplied screws, then insert the 4-pin connector into the motherboard or controller header; the keyed plug prevents reversed insertion.

What maintenance does the ball-bearing fan need over time?

The sealed ball bearing requires no lubrication; periodically remove dust from the blades and frame with compressed air to maintain airflow and prevent imbalance.

At what point does the 8.0W power draw limit continuous running?

The fan is rated for 12V 8.0W continuous operation; the practical limit is the system’s ability to supply stable 12V power and dissipate the heat the fan moves.
