Arctic Cooling - ACFAN00121A - Arctic Cooling P12 PWM PST CO Cooling Fan - 4.72" Maximum Fan Diameter - 421.2 gal/min Maximum Airflow - 1800 rpm - Dual Ball Bearing - 4-pin PWM - Case, Motherboard, Heatsink, Radiator

Optimised for Static Pressure

During the development of the new P12 PWM PST CO, special emphasis was placed on a focused airstream and thus a high static pressure. The fan guarantees extremely efficient cooling, even with increased air resistance. Therefore, the P12 PWM PST CO is particularly suitable for use on heatsinks and radiators.

More Efficient Technology

The motor is powered by a Neodym-Iron-Boron-Magnet ring of the newest generation, which allows the new P12 PWM PST CO to run much more efficiently than its predecessors. This saves energy and lowers the coil temperature without comprimising the performance.

For Continuous Operation

The premium quality Japanese dual ball bearing allows continuous operation 24/7 without the slightest compromise in performance. Dust and high temperature are affecting this bearing a lot less than generic sleeve or one ball bearings and thus make it the perfect choice when reliability is essential.

Maximum Quietness, Minimum Vibration

Even at low speeds the operating sound of the new ARCTIC motor is barely noticeable.
Due to a sinus-magnetizing the new motor only creates about 5 % of the vibration from commutation of a regular DC-motor without filter. Consequently, there is no need for rubber spacers due to the steady and smooth torque of the new motor.

Extended Life Span

A 10 °C lower motor temperature roughly doubles the life span of a fan.
The new ARCTIC motor has a four times longer service life through its low coil temperature.
Consequently, we have extended the warranty to 10 years.

200 to 1800 RPM regulated via PWM PST

With a wide range of regulation and the PWM Sharing Technology (PST), the P12 PWM PST CO fan speed can be controlled synchronously with all your other fans together. This keeps noise at a minimum while guaranteeing maximum cooling performance when needed.
