The P12 PWM features completely redesigned fan blades and is optimised for high static pressure. Thanks to this, it is especially effective when used on heatsinks and in situations with higher air resistance.The wide RPM range from 200 to 1800 RPM can be regulated steplessly via PWM.The newly developed motor with a low coil temperature significantly increases the life span of the fan. Therefore we have extended the warranty to 10 years.Maximum Quietness, Minimum VibrationEven 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 commutator oscillations of a regular DC-motor.Consequently, there is no need for rubber spacers due to the steady and smooth torque of the new motor. Optimised for Static PressureDuring the development of the new P12 PWM, 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 is particularly suitable for use on heatsinks and radiators. Extended Life SpanA 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. More Efficient TechnologyThe motor is powered by a Neodym-Iron-Boron-Magnet ring of the newest generation, which allows the new P12 PWM to run much more efficiently than its predecessors.This saves energy and lowers the coil temperature without comprimising the performance. 200 to 1800 RPM regulated via PWMThanks 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. High Quality BearingThanks to an alloy/lubricant combination developed in Germany, friction within the bearing is reduced and greater efficiency is achieved. As a result, there is less heat development as well as less bearing noise, which means you can enjoy a longer service life from your fan.
