Arctic ACFAN00133A P12 PWM (Black/Transparent) - Pressure-optimised 120 mm Fan with PWM

Key Features and Benefits:

• Optimized for static pressure
  During the development of the 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.
• More efficient technology
  The motor is powered by a neodym-iron-boron-magnet ring, which allows the P12 PWM to run much more efficiently than its predecessors. This saves energy and lowers the coil temperature without compromising the performance.
• Maximum quietness, minimum vibration
  Even at low speeds the operating sound of the Arctic motor is barely noticeable.
  Due to a sinus-magnetizing the innovative 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 motor.
• Extended life span
  A lower motor temperature roughly doubles the life span of a fan. The Arctic motor has a longer service life through its low coil temperature.
• 0 dB mode
  The P12 PWM is able to switch into silent passive mode when PWM signal is below 5% due to its motor. This allows working at your PC in complete silence without any unwanted noise.
