TSUJ 40 mm 12 V Cooling Fan

The TSUJ Kepler-C72J-OYS-0268 is a 40 mm square cooling fan rated for 12 V DC operation. It draws 0.07 A and uses a three-wire connection for speed monitoring. The unit suits 2-in-1 laptop maintenance or compact chassis airflow upgrades.

Three-Wire Speed Signal Accessory

The three-wire lead provides a tachometer signal so the host system can monitor fan speed in real time. This allows automatic thermal control without guesswork. Buyers who need a four-wire PWM control interface or a different voltage rating should look elsewhere.

Questions about this item

Will the 3-wire fan connector need replacing later?

The 3-wire connector is built into the fan assembly; if the tachometer lead fails the whole unit is swapped rather than the connector alone.

What limits continuous operation of this 12 V 0.07 A fan first?

The sleeve bearing wears before the motor windings, so bearing noise or speed drop appears ahead of electrical failure.
