The Noctua NF-P12 redux-1700 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 450 up to 1.700 RPM. This results in the fan producing a maximum of 25,1 dB(A) which is incredibly quiet, although it still manages to produce an impressive airflow of up to 120,2 m/h.The Features of the Noctua NF-P12 redux-1700 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 airflow1.700 RPM with 120,2 m/h & 25,1 dB(A)PWM control between 450 and 1.700 RPMSuperb quality backed by a 6 year manufacturer guaranteeThe Noctua NF-P12 redux-1700 PWM in DetailThe Noctua Nine-Blade Design with its Vortex Control Notch Technology enables the NF-P12 redux-1700 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 450- up to 1.700 RPM and produces an impressive airflow of up to 120,2 m/h. Due to the Vortex Control Notches, this fan is capable of producing an unusually low noise output of just 25,1 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-1700 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.
