ARCTIC

ARCTIC F12 PWM PST CO 120 mm Case Fan Black

SKU CH-Q95M-MJ87W

120 mm case fan with PWM sharing technology, dual ball bearing for continuous operation, 53 CFM airflow and 0.3 Sone noise at 1350 RPM

  • Optimised blade design delivers 53 CFM airflow at 0.3 Sone
  • PWM control adjusts speed precisely from 230 to 1350 RPM
  • PST shares one PWM signal across multiple fans
  • Japanese dual ball bearing supports 24/7 continuous operation
  • 4-pin connector enables full motherboard speed regulation

120 mm PWM Case Fan

The ARCTIC F12 PWM PST CO is a 120 mm case fan built for continuous 24/7 operation using a Japanese dual ball bearing. It targets system builders who need reliable airflow and low noise in desktop enclosures. The impeller design focuses on efficient ventilation while keeping acoustic output minimal. Speed is regulated through a standard 4-pin PWM connection.

PWM Sharing Technology Upgrade

This model adds PWM Sharing Technology (PST) so multiple fans can follow a single control signal from the motherboard or CPU cooler header. The feature lets case fans idle at low load and ramp up only when necessary, replacing setups that run every fan at fixed speed. The jump is worth it when you want coordinated, automatic speed curves across several fans without extra controllers.

Quiet-Cooled Build Suitability

The fan suits builders who prioritise a quiet chassis with up to 53 CFM airflow at 1350 RPM and a 0.3 Sone noise rating at that speed. It is not for buyers who need higher static pressure for dense radiators or restrictive filters. It is also not for systems that lack a 4-pin PWM header for speed control.

Questions about this item

What are the mounting dimensions for the 120 mm fan?

The fan uses the standard 120 mm mounting pattern with four screw holes spaced for typical case fan positions.

How do I connect multiple fans using the 4-pin PWM sharing technology?

Connect the first fan to the motherboard CPU header and daisy-chain additional fans using the PST cables so all fans follow one PWM signal.

When should the Japanese dual ball bearing be inspected or replaced?

The dual ball bearing is rated for continuous 24/7 operation; no scheduled replacement is required under normal use.
