ARCTIC P12 PWM PST CO 120 mm Case Fan

Pressure-Optimised 120 mm Case Fan

The ARCTIC P12 PWM PST CO is a 120 mm case fan designed for focused airflow and high static pressure. It uses a 4-pin PWM connector and supports PWM Sharing Technology to synchronise multiple fans from a single header. A Japanese dual ball bearing enables continuous 24/7 operation. The motor runs at lower coil temperature for extended service life.

Suited for Radiators and Restricted Airflow

Builders who need strong static pressure for radiators, dense mesh or dust filters will benefit from the pressure-optimised blade design. The fan speed range spans 200 to 1800 RPM with a 0 RPM mode below 5 % duty cycle. Systems that prioritise maximum airflow volume over pressure or require a different frame size should consider other options.

Sustained Load Behaviour

Under continuous load the motor maintains efficiency through a Neodym-Iron-Boron magnet ring that reduces coil temperature by roughly 10 °C. At 1800 RPM the fan delivers 56.3 CFM or 95.65 m³/h at 0.3 Sone. The dual ball bearing and lower operating temperature support a service life approximately four times longer than previous designs.
