Take advantage of increased airflow and reduced noise with the brown NF-F12 PWM 120mm Cooling Fan from Noctua. Using an SSO-bearing design, this 120mm cooling fan is designed for reliability. Thanks to a 4-pin PWM connection, fan speed can be controlled directly from your motherboard. Delivering 54.97 CFM of airflow at 300 to 1500 rpm and 22.4 dBA, this fan also comes with a low-noise adapter that can reduce fan speed to 1200 rpm while also reducing operational noise. Anti-vibration rubber pads are also included, as is a 4-pin Y cable, allowing users to control 2 fans from the same 4-pin motherboard connection. The Noctua NF-F12 PWM has a lifespan of more than 150,000 hours.
