TSUJ Kepler-C72J-OYS-0259 12V 3-wire fan

This TSUJ Kepler-C72J-OYS-0259 is a 12V cooling fan with a three-wire connection designed for the FD124020EB form factor. It suits technicians maintaining compatible 2-in-1 laptops or small-form-factor systems that require this specific replacement part. The unit is supplied new and ready for installation. Buyers needing a different voltage, connector type or frame size should look elsewhere.

Thermals noise and power at 9000 RPM

At 9000 RPM the fan moves air through a 40 by 40 by 20 mm frame while drawing 0.12 A from a 12 V rail. The three-wire lead allows the host system to monitor speed for automatic thermal control. Acoustic output will vary with mounting and case design but remains proportional to the high rotational speed. Power consumption stays low at the rated current.

Highlights

  • High airflow at 9000 RPM for efficient cooling
  • Low power draw of 0.12 A at 12 V
  • Compact 40 x 40 x 20 mm frame fits tight spaces

Questions about this item

How do I install the TSUJ Kepler-C72J-OYS-0259 fan and which step is often missed?

Align the 40x40x20mm housing with the FD124020EB mounting holes, connect the 3-wire plug to the 12V header, then secure all four screws; the step often missed is plugging the tachometer wire so the system reads 9000RPM speed.

What maintenance will the TSUJ Kepler-C72J-OYS-0259 need later?

Clean dust from the blades and vents every few months with compressed air; if bearing noise appears or RPM drops below 9000, replace the fan with another 12V 0.12A 40x40x20mm 3-wire unit.
