Pressure-optimised 120 mm fan for heatsinks

The Arctic P12 PWM PST is a single 120 mm case fan built for high static pressure. It suits builders who need focused airflow through dense fin stacks or liquid-cooling radiators. The fluid-dynamic bearing and 200 to 1800 RPM range deliver 56.3 CFM at a quiet 0.3 Sone.

PWM Sharing Technology simplifies cable routing

A 4-pin PWM connector and a matching 4-pin socket let multiple fans share one motherboard header. Each unit in the chain follows the same speed curve without extra splitters or controllers. The box includes four mounting screws so installation is immediate.

Low-vibration motor removes the need for rubber

Sinusoidal magnetisation cuts commutation vibration to roughly five percent of a conventional DC motor. The steadier torque runs cooler, which the maker links to a four-fold lifespan increase and a ten-year warranty. The 25 mm thick black frame fits standard 120 mm mounting points.

Questions about this item

Will the fluid dynamic bearing in this 120mm fan need lubrication or replacement after extended use?

The fluid dynamic bearing is sealed and designed for long life without user maintenance; the motor runs at a lower coil temperature, which the manufacturer says extends service life significantly.

What limits continuous high-speed operation at 1800 RPM on this pressure-optimised fan?

The 4-pin PWM control regulates speed up to 1800 RPM; sustained operation at that speed is limited by the 56.3 CFM airflow rating and the static-pressure design for heatsinks and radiators.

How much noise and heat does this P12 PWM PST produce when running all day at typical speeds?

At low speeds it reaches 0.3 Sone; the new motor design cuts vibration to about five percent of a regular DC motor and lowers coil temperature, reducing both noise and heat during continuous use.
