TSUJ Kepler-C72J-OYS-0131 12V server fan

This 40 mm by 56 mm case fan is designed for server chassis and compact workstations that require high-speed airflow in a slim profile. It suits system integrators and IT professionals who need reliable spot cooling for dense hardware layouts. The unit operates on a standard 12 V supply.

Thermals noise and power draw

The fan draws 1.23 A at 12 V, delivering strong airflow for its footprint while keeping power consumption predictable. High rotational speed produces audible noise typical of server-grade cooling, making it best suited for rack environments rather than quiet desktop builds. Thermal performance scales directly with the unrestricted intake and exhaust paths in the target chassis.

Questions about this item

How do I mount the 40×40×56 mm fan and wire the 12 V 1.23 A supply without reversing polarity?

Align the four 40 mm mounting holes with your case or bracket, secure with M3 screws, then connect the red lead to +12 V and the black lead to ground; reversing them will prevent the motor from starting.

When should I expect to replace the PMD1204PPBX-A bearing and how do I tell it is wearing out?

Plan on a bearing swap once the fan develops a audible rumble or the speed drops below the rated 4056 RPM; the sleeve bearing typically lasts several years at 12 V continuous duty.
