NFA12X25 G2 PWM, NF-A12X25 G2 PWM
Next-gen 12cm design
For unprecedented quiet cooling performance
State-of-the-art engineering
Progressive Bend impeller, Sterrox LCP material & ultra tight tip clearance
Highly optimised P/Q curve
For outstanding performance in all applications
The NF-A12x25 G2 is the second-generation, further improved successor to the groundbreakingNF-A12x25and 120mm sister model to the award-winning 140mmNF-A14x25 G2: Like its much-acclaimed predecessor, it is made fromSterrox LCPand features an extremely tight tip-clearance of only 0.5mm. At the same time, its further optimisedProgressive-Bendimpeller with winglets,Flow Acceleration Channelsand the new Centrifugal Turbulator Hub enable the G2 version to surpass the original NF-A12x25s performance, making it Noctuas 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 its 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 G2sAAO(Advanced Acoustic Optimisation) frame can be combined with the included NA-AVG1 anti-vibration gasket for a tighter seal on radiators or the optionalNA-IS1-12inlet 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-lossetaPERFmotor with Smooth Commutation Drive 2 technology doesnt only provide unprecedented energy efficiency and running smoothness, but thanks to the newSupraTorquefeature, 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 Noctuas reference-classSSO2bearing, a rich bundle of accessories and 6-year manufacturers 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 Noctuas portfolio and make it an elite choice for the most discerning demands.
