40 mm 24 V DC cooling fan

The TSUJ Kepler-C72J-OYS-0712 is a 40 mm axial fan designed for server and 2-in-1 accessory applications. It operates on 24 V DC power and draws 0.07 A, matching the A90L-0001-0551 and 109P0424H6D23 part references. The unit measures 40 by 40 by 20 mm and is supplied new. Builders who need a different voltage or a larger frame size will not be served by this model.

Thermals, noise and power draw

At 24 V DC the fan consumes 0.07 A, giving a low power draw for continuous server cooling. The compact 40 mm frame fits tight chassis spaces while moving air across drive bays or CPU heatsinks. Acoustic output is typical for a small axial design running at rated voltage. Users requiring higher static pressure or variable-speed control must look elsewhere.

Questions about this item

How do I install the 40mm DC24V fan into the 40x40x20mm slot and which step is often missed?

Align the four mounting holes, connect the two-wire lead to the 24 V header, then secure with screws; the step often missed is verifying airflow direction arrows point toward the heatsink before tightening.

What maintenance will the A90L-0001-0551 fan need and when should I replace it?

Clean dust from the blades and intake every six months with compressed air; replace the unit if bearing noise appears or RPM drops below the rated 0.07 A draw at 24 V.
