PC Fan NOCTUA NF-B9 redux 1600:The NOCTUA NF-B9 redux 1600 fan is based on the award-winning models that carry the NOCTUA branding. It uses the power of a nine blade integrated rotor with a diameter of 92mm. The speed of the blades reaches up to 1,600 rpm. Airflow is increased from notches on the blade tips. The motherboard is connected via a 3-pin fan connector. It will also offer an unprecedented operation time of up to 150,000 hours (17 years old). All this with excellent performance, the legendary quiet operation and all the other great features that every true geek will appreciate. SSO bearings The time-tested proprietary Noctua bearing has been improved to help ensure the quietest possible operation. NOCTUA NF-B9 redux 1600 uses the optimised SSO bearing, which is located nearer the rear magnet axis and thus offers better stabilisation, precision and durability. Extensive support for connection Users can choose from a wide range of optional Noctua accessories such as anti-vibration pads, adaptors for low noise, y-cables, 3:4 pin adapter or extension cord to refine the Redux Edition according to individual needs. With the extension cord it is even possible to install and connect the fan in large and bulky cabinets.Additional information: Base: Bearing: SSO (self-stabilising oil-bearing)Speed range: 350-1,600 rpm.Airflow: 64.3 m3/hNoise level: 17.6 db(A)Max. power consumption: 1.32 WMax. current consumption: 0.11 AVoltage: 12 VLifetime:> 150,000 hoursStatic Pressure: 1.61mm H2OConnector: 3-pinStandard packaging: Fan NOCTUA NF-B9 redux 16004 fan screws
