During the development of the new P14 PWM PST, 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 P14 PWM PST is particularly suitable for use on heatsinks and radiators. The speed of the fan can be throttled down to standstill via PWM. This allows silent operation in IDLE and at the same time guarantees maximum performance when required. Even at low speeds the operating sound of the new ARCTIC motor is barely noticeable. Due to sinus-magnetizing the new motor only creates about 5 % of the vibration from the commutation of a regular DC motor without a filter. Consequently, there is no need for rubber spacers due to the steady and smooth torque of the new motor. Thanks to the 4-Pin Connector, the rpm can be regulated in a broad spectrum via PWM. In this way, noise is kept at a minimum while maximum cooling performance is guaranteed when needed.
