Replacement fan for PMD1204PQB1-A

This 40 mm square cooling fan is designed as a direct replacement for the PMD1204PQB1-A model. It operates at 12 V and draws 3.7 W while spinning at 9500 RPM. The four-wire connector supports speed control and monitoring.

40x40x28 mm form factor limits installation

The unit measures 40 mm by 40 mm by 28 mm thick, so it only fits chassis or heatsink openings that match those exact dimensions. Builders needing a different footprint or a lower noise profile cannot use this model.

Questions about this item

Which TSUJ Kepler-C72J-OYS-0255 variant matches my laptop's original PMD1204PQB1-A fan?

This single listing is built for the PMD1204PQB1-A 12 V 3.7 W 9500 RPM 40 × 40 × 28 mm four-wire cooler, so choose it when your service manual cites that exact part number.

What does the 9500 RPM rating mean once the fan is installed in my 2-in-1?

At full speed the impeller spins at 9500 revolutions per minute, moving the maximum airflow the 40 mm frame can deliver; the four-wire PWM connection lets the system lower that speed automatically when thermal load drops.
