CAFELE CNDC24Z4P-977 24V 120mm 38mm 10W case fan

SKU CH-DCXA-GNVNT MPN CNDC24Z4P-977

A 24 V DC case fan measuring 120 × 120 × 38 mm draws 0.42 A at 10 W for inverter and servo cooling

  • Product typeCase Fan
  • 120 mm square frame fits standard 120 mm mounts
  • 38 mm thick profile suits deeper fan slots
  • 24 V DC input matches industrial servo supplies
  • 42 A draw keeps power budget low
  • 10 W rated power for reliable cooling performance

24 V 120 mm server fan

This 120 mm by 38 mm case fan runs on 24 V DC and draws 0.42 A for a rated 10 W. It is built for equipment that supplies a 24 V rail rather than the 12 V common in desktop PCs.

Replaces worn 24 V 12038 units

The jump is worth it when an existing 24 V inverter or servo fan of the same 12038 footprint has become noisy or unreliable. It is not for builders who need a standard 12 V PWM fan for a consumer motherboard header.

Limited to 24 V DC power sources

The fan requires a 24 V supply capable of at least 0.42 A; it will not start on 12 V headers or typical fan controllers. No speed signal or PWM input is mentioned in the data, so automatic speed control cannot be assumed.

Questions about this item

What are the exact mounting dimensions of the 12038 frame?

The fan measures 120 × 120 × 38 mm with standard 120 mm hole spacing for direct case or radiator mounting.

How do I wire the four-pin servo connector to a 24 V DC source?

Connect the red lead to +24 V and black to ground; the yellow wire carries the tach signal and the blue wire accepts PWM control from the controller.

When should I plan to replace the bearings on this 10 W unit?

Expect bearing wear after several years of continuous 24 V operation; increased noise or reduced RPM signals it is time for a new fan.
