Replacement 4028 4-pin cooling fan

This 12 V 9.6 W fan is built as a direct drop-in for compatible laptop cooling pads. It suits repair technicians and owners who need to restore airflow after the original cooler fails. Each unit is tested before shipping and arrives new in a single-fan package.

Thermals noise and power draw

Rated at 9.6 W, the fan draws modest power from a 12 V rail while delivering the airflow the pad was designed for. The four-pin connector supports PWM control so speed and noise scale with thermal demand. No additional specifications for acoustic output or static pressure are provided by the supplier.

Upgrade context and compatibility

This part replaces a worn or noisy PSD1204PQBX-A cooler in the same form factor. The jump is worth it when the original fan spins unevenly, rattles or stops entirely. Buyers who need a different voltage, connector pin count or physical dimensions should verify the part number against their device before ordering.

Questions about this item

How do I install the 4-pin PSD1204PQBX-A fan and what step is often missed?

Align the 4-pin connector with the motherboard header, secure the 4028 frame with the original screws, then verify the 12 V 9.6 W rating matches the laptop's power spec before closing the case.

What maintenance or replacement will the PSD1204PQBX-A need later?

Clean dust from the 4028 blades every few months with compressed air; replace the fan if bearing noise appears or if the 12 V 9.6 W unit no longer spins at full speed.

What limit appears first on the PSD1204PQBX-A under sustained load?

The 9.6 W power ceiling caps airflow; prolonged 100 % duty cycles can hit thermal limits of the 4028 motor before the 12 V supply throttles.
