ARCTIC F12 PWM 120 mm Case Fan Black

120 mm PWM Case Fan

The ARCTIC F12 PWM is a 120 mm case fan built for system builders who want reliable airflow with low acoustic output. A 4-pin PWM connector lets the motherboard control speed automatically from 230 to 1350 RPM. The impeller design targets efficient ventilation while keeping turbulence low. A fluid dynamic bearing with an oil capsule reduces lubricant leakage for longer service life.

Builders who need quiet, adjustable cooling

This fan suits anyone assembling or upgrading a desktop who wants the motherboard to manage fan speed without manual intervention. The two-way mounting option supports both intake and exhaust configurations. Buyers who require higher static pressure for dense radiators or restrictive filters should look at specialised models. Users without a 4-pin PWM header on their board cannot use the automatic regulation feature.

Airflow and noise headroom

At full speed the fan moves 53 CFM or 90.1 m³/h with a noise level of 0.3 Sone. The wide 230–1350 RPM range provides headroom for silent idle operation and stronger airflow under load. The bearing design maintains consistent performance over time without the wear typical of simpler sleeve bearings. In very restrictive layouts the available pressure may become the limiting factor.
