PC Fan NOCTUA NF-P14r redux 1500 PWM:The NOCTUA NF-P14r redux 1500 PWM fan comes from award-winning models that have been awarded the NOCTUA branding lamp. It employs the power of nine blades of an integrated 140 mm diameter rotor. Blade speeds are up to 1500 RPM. Air flow is increased by notches at the end of the blades. To the motherboard, the fan is connected via a 4-pin connector. It also offers an unprecedented average time of trouble-free operation, of over 150,000 hours (17 years!). All of this with outstanding performance, legendary quiet operation, and all the great features that will be appreciated by true computer enthusiasts. Innovative PWM IC control with SCD NOCTUA NF-P14r redux 1500 PWM supports fully automatic speed control. Its main advantage is the Smooth Commutation Drive (SCD), which eliminates undesirable jumps and delivers quieter operation, especially at slower rotation speeds. SSO bearings Well-proven proprietary Noctua bearings have been further refined to provide the quietest possible operation. The NOCTUA NF-P14r redux 1500 PWM uses optimized SSO bearings with a rear magnet positioned closer to the axis, offering improved stability, precision, and durability. Extensive connection support Users can choose from a wide selection of optional Noctua accessories such as antivibration pads, low noise adapters, y cables, 3: 4 pin adapters, or an extension cable to refine the Redux edition to suit your individual needs. Thanks to the extension cable, it is possible to install, and connect, the fan even in large and bulky cabinets .Additional information:Basic:Bearing: SSO (self-stabilizing oil bearing)Speed ??range: 450-1500 rpm.Air flow: 133.7 m3 / hNoise level: 25.8 dB (A)Max.
