40 mm 12 V server fan

The TSUJ AD04012HB285B00 is a 40 mm square fan built for server and appliance cooling. It runs on a 12 V supply and draws 0.56 A. The frame measures 40 mm by 40 mm by 28 mm. This size fits many 1U rack units and compact network gear.

12 V power limit

The fan requires a stable 12 V source capable of at least 0.56 A. Voltage outside this rating will prevent operation or reduce airflow. No PWM or speed-control interface is described, so the unit runs at a fixed speed when powered. Builders needing variable control or a different voltage must choose another model.

Questions about this item

How do I confirm this 40×40×28 mm server fan matches my chassis mount?

Check that your mounting holes accept a 40 mm square frame with 28 mm depth and that the 12 V 0.56 A rating fits your fan header.

What does the 12 V 0.56 A rating mean for daily operation?

The fan draws 0.56 A from a 12 V supply, so your fan controller or motherboard header must deliver at least that current.
