ARCTIC P14 PWM PST (5 Pack) - PC Fans, 140mm Case Fan with PWM Sharing Technology (PST), Pressure-optimised, Quiet Motor, Computer, Fan Speed: 200–1700 RPM (0 RPM <5%) - Black

OPTIMISED FOR STATIC PRESSURE: Fan guarantees extremely efficient cooling, even with increased air resistance, therefore, the P14 PWM PST is particularly suitable for use on heatsinks and radiators. 200 TO 1700 RPM (0 rpm <5 %) REGULATED VIA PWM PST: Thanks to 4-pin connector, the RPM can be regulated in a broad spectrum via PWM, noise is kept at 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 PST to run much more efficiently than its predecessors. 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. TECHNICAL DATA: 5 Pack, Fan speed: 200–1700 rpm (0 rpm <5 %), Airflow: 72.8 cfm | 123.76 m³/h, Noise Level: 0.3 Sone, Static pressure: 2.40 mmH₂O, Pin: 4-pin
