TSUJ 2-in-1 accessory for 12V 0.33A cooling fan

This TSUJ 2-in-1 accessory is designed specifically for the PMD1204PQB1-A 12V 0.33A 4.0W 9500RPM 40X40X28MM 3-wire cooling fan. It provides the necessary connection interface to integrate the fan into compatible 2-in-1 laptop systems. The part number Kepler-C72J-OYS-0248 identifies this specific accessory kit. It serves technicians and builders who need to install or replace this exact fan model.

Sustained operation with 3-wire speed monitoring

The accessory supports the fan's 3-wire configuration, allowing the system to monitor rotational speed continuously during extended use. This feedback enables the laptop's thermal management to adjust fan behaviour based on actual RPM data rather than assuming fixed output. Under prolonged load, the connection maintains signal integrity so the controller receives real-time speed information. Buyers who need 4-wire PWM control or a different voltage rating cannot use this accessory.

The fan spins at 9500 RPM and draws 0.33 A at 12 V, producing a typical airflow noise level for a 40 mm frame at that speed.

What connector does the 3-wire cooling fan need on the host device?

It requires a standard 3-pin 12 V fan header on the motherboard or controller board to power and monitor the 4.0 W motor.
