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

#ad
ARCTIC #ad - 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.

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. 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.

Technical data: fan speed: 200–1700 rpm, airflow: 72;8 cfm/123;76 m³/h @ 1700 RPM, noise level: 0;3 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.

Black/White, Computer, Almost inaudible, Extra Quiet Motor, ARCTIC F14 Silent, 140 mm Case Fan, Ultra-Quiet, Fan Speed: 800 RPM

#ad
ARCTIC #ad - Long service life: the fluid dynamic bearing comes with an oil capsule that avoids lubricant leakage, thus this bearing is as quiet as a sleeve bearing but comes with a higher service life.

Technical data: fan speed: 800 rpm, airflow: 46 cfm/78 m³/h @ 800 rpm, noise Level: 0;08 Sone @ 800 RPM, Pin: 3-pin. Greater efficiency - less noise at higher airflow: At low fan speed, the motor noise is key, a motor developed in Germany with a new alloy/lubricant combination reduced friction and noise. Two way installation: Blow warm air out of the case, draw cool air into your case. Innovative design: design of fan blades improves air flow and facilitates efficient ventilation, impeller was designed with a focus on minimzing the noise level yet delivering the desired airflow and pressure.
