9. ARCTIC

#ad

140 mm Case Fan with PWM, Fan Speed: 200-1700 RPM, Black, Pressure-optimised, Very Quiet Motor, Computer, ARCTIC P14 PWM

#ad
ARCTIC #ad - 200 to 1700 rpm regulated via pwm: thanks to 4-pin connector, the RPM can be regulated in a broad spectrum via PWM, noise is kept at a minimum while maximum cooling performance is given when needed.

Technical data: fan speed: 200–1700 rpm, airflow: 72. 8 cfm/123. 76 m³/h @ 1700 rpm, noise Level: 03 sone @ 1700 rpm, pin: 4-pin. Extended life span: a 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. Optimised for static pressure: the fan guarantees extremely efficient cooling, even with increased air resistance, therefore, the P14 PWM is particularly suitable for use on heatsinks and radiators.

More efficient technology: the motor is powered by a Neodym-Iron-Boron-Magnet ring of the newest generation, which allows the new P14 PWM to run much more efficiently than its predecessors.
