During the development of the new P12 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 P12 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. Numerous improvements, such as updated engine technology and a newly developed fan design, have noticeably increased the performance of P-fans. In internal performance tests leveled to 28 dB(A), the new P-fans left many competitors behind. The motor is powered by a PWM IC of the newest generation, which allows the new P12 PWM PST to run much more efficiently than its predecessors. This saves energy without compromising the performance. 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 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.
