Noctua today introduced its eagerly anticipated next-generation 140mm fan. Succeeding the award-winning NF-A14 and building on the technological innovations of the ground-breaking NF-A12x25, the NF-A14x25 G2 is Noctua’s new 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 0.7mm allow the NF-A14x25 G2 to significantly improve its predecessor’s renowned quiet cooling performance.
“After almost a decade of development work, we’re proud of the substantial performance uplift that we have managed to achieve with this fan“, says Roland Mossig (Noctua CEO). “The NF-A14x25 G2 is easily our most advanced fan today, and we’re confident that the massive advances in performance-to-noise efficiency will be of great value to our customers.”
Like the NF-A14 and NF-A12x25, the new NF-A14x25 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-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 NF-A14x25 G2’s new 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.
The fan is available in a standard PWM version with 1500rpm maximum speed, an ultra-quiet LS-PWM version with up to 800rpm as well as in an Sx2-PP set that contains two fans that are offset in speed by +/- ~25rpm. This speed offset can be beneficial in push-pull operation as well as in situations where two or more fans are operating side by side, such as in case cooling applications or on 280mm water cooling radiators, in order to avoid periodic humming or other undesired acoustic interaction phenomena.
Topped off with Noctua’s reference-class SSO2 bearing, a rich bundle of accessories and 6-year manufacturer’s 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 Noctua’s portfolio and make it an elite choice for the most discerning demands.
