Featuring advanced aerodynamic design elements like the Progressive Bend impeller and Centrifugal Turbulator hub, it delivers superior airflow and efficiency. Constructed from Sterrox LCP with ultra-tight tip clearance, it excels in demanding applications such as CPU coolers and water cooling radiators. With 4-pin PWM automatic speed control, ultra-low noise operation, and premium-grade SSO2 bearings rated for over 150,000 hours, this fan combines durability, precision, and whisper-quiet performance for the discerning professional. ## Description Product Description 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, 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. Progressive-Bend impeller The NF-A12x25 G2 features a unique Progressive-Bend impeller with Flow Acceleration Channels and winglets. Its nine blades are swept backwards close to the hub and progressively bent forward further out. Working in tandem with the Centrifugal Turbulator hub, this design not only helps to push more air towards the outer blade areas where efficiency is higher but also assures maximum lift and near uniform loading across the entire blade span. Centrifugal Turbulator hub Acting as a turbulator, the new Centrifugal Turbulator hub design improves flow attachment in the hub region. At the same time, its centrifugal driving motion pushes air outwards from the hub area where efficiency is low due to the slow rotational speed towards the outer, high-efficiency zones of the blades, thereby increasing overall efficiency by optimising fluid distribution across the impeller area. SSO2 Bearing The NF-A12x25 G2 features the further optimised second generation of Noctua's renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. Ultra-tight tip clearance The NF-A12x25 G2 has an extremely tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.5mm. This highly ambitious design helps the NF-A12x25 G2 to work more efficiently against back pressure, such as on heatsinks or radiators, by reducing leak flows through the gap between impeller and frame. Scope of delivery NA-RC7 Low-Noise Adaptor (L.N.A.) NA-YC1 4-pin PWM splitter cable NA-EC1 30cm extension cable 4x NA-AV2 anti-vibration mounts NA-AVG1 anti-vibration gasket for water cooling radiators Fan screws Highly optimised P/Q curve for all applications The NF-A12x25 G2’s sophisticated aerodynamic design allows for a pressure to airflow (P/Q) curve that is extremely strong in the critical mid-section. This means that the NF-A12x25 G2 is a true jack-of-all-trades with excellent performance in both static pressure and airflow demanding applications. Review: Expensive But Worth It - They're incredibly silent, move a load of air, and the static performance for my AIO is brilliant. I've installed 6 inside of my Fractal North (3x Upfront, 1x Exhaust, and 2x as exhaust on my 240mm AIO). They are expensive but they are worth it - they don't have any low annoying whine noise and Noctua are notorious for their incredible customer support so the reassurance of a strong warranty is worth that little bit extra.
