SUNON 120 mm 12 V axial fan

The SUNON KD1212PMBX-6A is a 120 × 120 × 38 mm axial fan rated at 12 VDC with a voltage range of 10.2 ~ 13.8 VDC. It draws 0.63 A for 7.6 W of power and spins at 3150 RPM using a ball bearing.

Suited for industrial cooling

This fan serves medical devices, rail vehicles, drive cooling, industrial cleaning systems and electronic products where steady airflow matters. It is not suited for builds needing PWM speed control or noise levels below the rated 46.5 dB(A).

120 CFM airflow at 3150 RPM

The fan delivers 120 CFM of wind capacity with a static pressure of 84.7 Pa. That single airflow figure decides whether the unit meets the thermal demands of your chassis or heat exchanger.

Questions about this item

How do I mount the 120 mm fan and what is the common mistake with the 38 mm depth?

Use the four corner screw holes on the 120 x 120 mm frame; the frequent error is choosing screws that are too long for the 38 mm thickness and hitting internal components.

What part will need replacement first on this ball-bearing fan?

The ball bearing itself is the wear item; expect it to require replacement after extended continuous operation at 3150 RPM.

At 46.5 dB(A) and 7.6 W, what limit appears first during sustained use?

The acoustic limit of 46.5 dB(A) is usually noticed before the 7.6 W thermal limit becomes an issue in typical chassis airflow.
