ARCTIC COOLING AFACO-120PC-GBA01 120mm PWM case fan 600-1350 RPM 74 CFM

120 mm PWM case fan for continuous operation

The ARCTIC F12 PWM CO is a single 120 mm case fan designed for systems that run 24 hours a day, seven days a week. It uses a Japanese dual ball bearing to reduce rotational friction, which extends the operating lifespan. The fan accepts a PWM signal from the CPU header and forwards it to coordinate the entire case ventilation system. Setup is quick and requires no separate controller.

Sustained airflow at 0.5 Sone noise level

At full speed the fan reaches 1350 RPM and delivers 74 CFM of airflow, while the minimum speed sits at 600 RPM. The bearing design keeps friction low during non-stop rotation, so acoustic output remains steady rather than rising as the unit ages. The PWM curve allows the motherboard to scale speed precisely to thermal load, maintaining consistent cooling without sudden speed spikes. Continuous operation is the intended workload rather than short bursts.

Dual ball bearing build with standard mounting

The frame measures 120 by 120 by 25 mm and fits any standard 120 mm mounting points in modern chassis. Black blades and frame suit neutral colour schemes without drawing attention. The dual ball bearing construction is less sensitive to orientation, so the fan can be mounted as intake, exhaust or on a radiator without affecting durability. A six-year limited warranty from the manufacturer covers the unit.
