Noctua today unveiled its long-awaited next-generation 140mm fan. Successor to the award-winning NF-A14 and building on the technological innovations of the innovative NF-A12x25, the NF-A14x25 G2 is Noctua's new flagship model with a 140mm square frame: manufactured with Sterrox LCP, its progressive curvature highly optimized The impeller with fins, flow acceleration channels and centrifugal turbulator hub, combined with a tip clearance of just 0.7mm, enable the NF-A14x25 G2 to significantly improve the renowned quiet cooling performance of its predecessor.
“After almost a decade of development work, we are proud of the substantial performance increase we have managed to achieve with this fan,” says Roland Mossig (CEO of Noctua). “The NF-A14x25 G2 is easily our most advanced fan today and we are confident that the huge advances in performance and 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 produces excellent results in all types of use, regardless of whether it is low impedance applications oriented to airflow, such as case cooling, or demanding static pressure and high impedance scenarios, such as in heat sinks and water cooling radiators. For application-specific optimization, the NF-A14x25 G2 comes with a NA-AVG2-LR anti-vibration gasket pre-installed to create a tighter seal on the radiators. Additionally, its AAO (Advanced Acoustic Optimization) frame can be combined with the optional NA-IS1-14 inlet spacer, which can help achieve superior suction acoustics and flow rates in challenging inlet configurations.
The NF-A14x25 G2's new ultra-low-loss etaPERF motor with Smooth Commutation Drive 2 technology not only provides unprecedented energy efficiency and smooth running, but thanks to the new SupraTorque function, it can also take advantage of additional torque headroom. to keep the fan at the desired speed when working against back pressure, thus guaranteeing even better performance in heatsinks and radiators.
The fan is available in a standard PWM version with a maximum speed of 1500 rpm, an ultra-quiet LS-PWM version with up to 800 rpm, as well as in an Sx2-PP set containing two fans with +/- speed compensation ~25rpm. . This speed compensation can be beneficial in push-pull operation, as well as in situations where two or more fans operate side by side, such as in case cooling applications or 280mm water cooling radiators, to avoid periodic humming or other unwanted effects. Acoustic interaction phenomena.
Completed with Noctua's flagship SSO2 bearing, an extensive accessory package, and a 6-year manufacturer's warranty, the NF-A14x25 G2 is a premium product in every way. Its superior performance, comprehensive feature set, cutting-edge construction and cutting-edge materials set a new standard within Noctua's portfolio and make it an elite choice for the most demanding demands.
