Noctua NF-A12x25 G2 PWM 12V 2nd Gen Premium Quiet 120mm Fan NF-A12X25-G2

[features] The NF-A12x25 G2 is the second-generation; further improved successor to the groundbreaking NF-A12x25 and 120mm sister model to the award-winning 140mm NF-A14x25 G2: Like its much-acclaimed predecessor; it is made from Sterrox LCP and features an extremely tight tip-clearance of only 0.5mm. At the same time; its further optimised Progressive-Bend impeller with winglets; Flow Acceleration Channels and the new Centrifugal Turbulator Hub enable the G2 version to surpass the original NF-A12x25’s performance; making it Noctua's undisputed new flagship in the 120mm range. Just like its predecessor and the 140mm version; the NF-A12x25 G2 is a true all-rounder that yields superb results in all types of usage; regardless of whether it's in low-impedance; airflow-oriented applications such as case cooling; or high-impedance; static pressure demanding scenarios such as on heatsinks and water cooling radiators. For application-specific optimisation; the NF-A12x25 G2's AAO (Advanced Acoustic Optimisation) frame can be combined with the included NA-AVG1 anti-vibration gasket for a tighter seal on radiators or the optional NA-IS1-12 inlet side spacer frame; which can help to achieve superior suction acoustics and flow rates in challenging 'pull' configurations.
The 4-pin PWM version supports fully automatic speed control via PWM fan headers and comes with a Low-Noise Adaptor to reduce the maximum speed from 1800 to 1500rpm. Its ultra-low-loss etaPERF motor with Smooth Commutation Drive 2 technology doesn't only provide unprecedented energy efficiency and running smoothness; but thanks to the new SupraTorque feature; it can also leverage extra torque headroom to keep the fan at its desired speed when working against back pressure; thereby ensuring even better performance on heatsinks and radiators. Topped off with Noctua's reference-class SSO2 bearing; a rich bundle of accessories and 6-year manufacturer's warranty; the NF-A12x25 G2 is a premium-quality product through and through. Its superior performance; comprehensive feature set; cutting-edge construction and state-of-the-art materials set a new standard within Noctua's portfolio and make it an elite choice for the most discerning demands.
