TSUJ 4028 3-wire server cooling fan

The TSUJ Kepler-C72J-OYS-0393 is a 4028 form-factor fan built for server and 2-in-1 accessory applications. It operates on 12 V DC at 0.28 A with a three-wire connection for speed monitoring. The double ball bearing design targets continuous operation in compact chassis.

Sustained load behaviour with double ball bearings

Under continuous duty the double ball bearing construction maintains consistent rotation without the wear pattern of sleeve alternatives. The 12 V 0.28 A draw remains stable during prolonged airflow delivery. The three-wire interface allows the host system to track RPM and adjust curves as thermal load changes.

Questions about this item

How much noise and heat does the Kepler-C72J-OYS-0393 fan produce when running continuously at 12V?

The double ball bearing design and 0.28A draw at 12V keep operating noise low and heat output minimal during all-day server cooling duty.

What power connector must my system already provide for this 3-wire 4028 fan?

Your motherboard or fan controller needs a standard 3-pin 12V header to supply the 0.28A current this Kepler-C72J-OYS-0393 requires.
