The fan can be used both in a case and on radiators. A pre-installed sealing lip ensures better compression when used on radiators. This ensures efficient cooling of your gaming PC at all times and at any performance level. Powerful cooling thanks to high-end materials With its 1,500 revolutions per minute, your components are kept at low temperatures. Despite its powerful cooling, it's surprisingly quiet: in normal mode, it reaches a noise level of just 24.8 dB(A) . You also get a low-noise adapter with the fan. This reduces the fan's maximum speed to 1,250 rpm, making it significantly quieter at 19.7 dB(A). You can choose whether you prefer faster revolutions or a quieter noise level. The fan also boasts a static pressure of 2.56 mmH2O and an airflow of up to 155.6 m³/h . This makes them ideal for use on radiators and for building your own custom water cooling system. The NF-A14x25 G2 is made of glass fiber-reinforced LCP (Liquid Crystal Polymer) material . Liquid crystal polymers exhibit significantly higher mechanical strength and temperature resistance than conventional plastics. These properties ensure reduced vibration, high stability, and durability. Noctua's own The NF-A14x25 G2 uses Noctua's proprietary SSO2 bearing . This reduces noise and increases stability, while also increasing the longevity of the fans.

Noctua NF-A14x25 G2 PWM 140mm Chassis Fan

Succeeding the award-winning NF-A14 and building on the technological innovations of the ground-breaking NF-A12x25, the NF-A1... more4x25 G2 is Noctua’s 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 0.7mm allow the NF-A14x25 G2 to further improve its predecessor’s 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 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 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 1500 to 1250rpm. 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 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.
