Noctua NF-A14x25 G2 LS-PWM, Premium-Quality Ultra-Quiet 140mm PC Fan, 4-pin (Brown)

Succeeding the award-winning NF-A14 and building on the technological innovations of the ground-breaking NF-A12x25, the NF-A14x25 G2 is Noctuas next-generation square-frame 140mm flagship model: Made from Sterrox LCP, its highly optimised Progressive-Bend impeller with winglets, Flow Acceleration Channels and Centrifugal Turbulator hub combined with a tip-clearance of only 0.7 mm allow the NF-A14x25 G2 to further improve its predecessors renowned quiet cooling performance. Like the NF-A14 and NF-A12x25, it 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-A14x25 G2 comes with an NA-AVG2-LR anti-vibration gasket pre-installed to create a tighter seal on radiators. Additionally, its AAO (Advanced Acoustic Optimisation) frame can be combined with the optional NA-IS1-14 inlet spacer, which can help to achieve superior suction acoustics and flow rates in challenging intake configurations. The 4-pin LS-PWM version is a low-speed, PWM-enabled variant that is ideal for semi-passive setups or ultra-low-noise applications that require near-silent acoustics and PWM based speed control. Its super-low-loss etaPERF motor with Smooth Commutation Drive 2 technology combines unprecedented energy efficiency with a superb running smoothness that is guaranteed to satisfy even the most noise-sensitive users.

Topped off with Noctuas reference-class SSO2 bearing, a rich bundle of accessories and 6-year manufacturers warranty, the NF-A14x25 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.
