5. ARCTIC

#ad

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

#ad
ARCTIC #ad - 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.

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. Technical data: fan speed: 800 rpm, noise level: 0;08 sone @ 800 RPM, airflow: 46 cfm/78 m³/h @ 800 rpm, Pin: 3-pin. Two way installation: Blow warm air out of the case, draw cool air into your case. 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.

7. ARCTIC

#ad

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

#ad
ARCTIC #ad - 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, therefore, even with increased air resistance, 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.

Technical data: fan speed: 200–1700 rpm, noise level: 0;3 sone @ 1700 rpm, airflow: 72;8 cfm/123;76 m³/h @ 1700 rpm, Pin: 4-pin.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.
