SXDOOL 120 mm PWM dual-ball fan

This 120 mm case fan uses a dual-ball bearing and a four-wire PWM interface for motherboard speed control. It runs on 12 V at 0.65 A and spins between 1000 and 3600 RPM. The unit measures 120 x 120 x 25 mm and includes a 47 cm lead.

Upgrade from sleeve-bearing or three-pin fans

The dual-ball design reduces wear compared with sleeve bearings, while PWM replaces fixed-voltage control. The speed range suits builds that need quiet idle and strong load airflow. It does not address radiators thicker than 25 mm or systems requiring a shorter cable.

Questions about this item

Will the 120mm frame and 25mm thickness fit my case fan mounts?

The fan measures 120mm square by 25mm thick, matching standard 120mm mounting holes.

How do I connect the 4-pin PWM cable to the motherboard, and what mistake should I avoid?

Plug the 4-pin connector into a motherboard PWM header; do not use a 3-pin header or you will lose speed control.
