Arctic Pressure-optimised 140 mm Fan with PWM PST

Key Features and Benefits:

• More efficient technology
  The motor is powered by a neodym-iron-boron-magnet ring, which allows the P14 PWM PST 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 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.
• 0 dB mode
  The P14 PWM PST is able to switch into silent passive mode when PWM signal is below 5 % due to its innovative motor. This allows working at your PC in complete silence without any unwanted noise.
• High quality bearing
  Thanks 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.
