Arctic is best known for its very quiet CPU cooler. The innovative fans make a significant contribution to this reputation. With the inexpensive F series , Arctic also offers its fans with a regular frame design that can be used universally in housings, on coolers and on radiators.The Arctic F14 PWM PST 140 mm fan generates an air flow of 126 m / h (74.16 cfm) and a static pressure of 1.3 mmH2O at 1,350 rpm . The connection is made via a 4-pin PWM connector. This version of the F14 also supports the PWM Sharing Technology (PST), so that the fan speed of the F14 PWM PSTcan be synchronized with other fans. Arctic uses a high-quality, hydrodynamic slide bearing. This not only guarantees smooth operation, but also ensures that the volume does not increase over time. With an enormous guarantee period of ten years, this information is not only promised.Technical details:- Dimensions: 140 x 140 x 27 mm- Weight: 181 g- Material: Plastic- Colour: Black- Volume: 0.5 sone / 24.4 dB (A)- Speed: 200 - 1,700 rpm- Static pressure: 1.3mm H20- Airflow: 126 m / h (74.16 cfm)- Voltage: 12V- Starting voltage: 6V- Amperage: 0.11A- Connection: 4-pin PWM PST- Cable length: 400 mm- Guarantee: 10 years
