The Noctua NF-P12 redux-1300 PWM combines the best of both worlds. Firstly the fan offers the Noctua-level quality we\'ve come to expect, but it forgoes a few small features so as to offer an exceptionally competitive price instead. The redux product line offers an attractive colour scheme consisting of light and dark grey. Equipped with a 4-Pin PWM connector the fan\'s speed can be regulated by the motherboard and runs from 300 and 1.300 RPM. This results in the fan producing a maximum of 19,8 dB(A) which is incredibly quiet, although it still manages to produce an impressive airflow of up to 92,3 m/h. The Features of the Noctua NF-P12 redux-1300 PWM Fan at a Glance:SSO-bearings for high performance, quiet operation and increased durabilityPressure-optimised rotor blades with impressive static pressure and airflowVortex Control notches for reducing noise from airflow1.300 RPM with 92,3 m/h & 19,8 dB(A)PWM control between 300 and 1.300 RPMSuperb quality backed by a 6 year manufacturer guaranteeThe Noctua NF-P12 redux-1300 PWM in DetailThe Noctua Nine-Blade Design with its Vortex Control Notch Technology enables the NF-P12 redux-1300 PWM to produce an increased volume of airflow and is especially well-suited for use on CPU coolers or as a case fan. The 120 mm fan spins at 300- up to 1.300 RPM and produces an impressive airflow of up to 92,3 m/h. Due to the Vortex Control Notches, this fan is capable of producing an unusually low noise output of just 19,8 dB(A). This is ideal for people who really appreciate quiet fans as well as those interested in overclocking! Thanks to the Smooth Commutation Drive 2, the NF-P12 redux-1300 PWM is kitted out with the newest drive system produced at Noctua. Unwanted movements produced due to centripetal force are drastically reduced and this aids in making the fan surprisingly quiet during operation. In order to optimise what was already a very good fan, Noctua has integrated the sought after SSO Bearing Technology, meaning that long-term stability during operation is assured.Specification:Dimensions: 120x120x25 mmConnection: 4-Pin PWMBearing Type: SSO-BearingBlade Geometry: Pressure-optimised Nine Blade Design with Vortex-Control NotchesRPM: 300 - 1.300 RPMMax.
