NOCTUA NF-A14x25 G2 PWM 140mm FanExperience the next generation of cooling performance with the NOCTUA NF-A14x25 G2 PWM, a meticulously engineered 140 mm fan designed to set a new benchmark for quiet, high-efficiency cooling. As the successor to Noctu´s iconic and award-winning NF-A14, this fan is the result of years of advanced aerodynamic research, pushing the boundaries of what´s possible in a 140 mm form factor. It is the ultimate choice for discerning enthusiasts who demand uncompromising performance and near-silent operation for their high-end PC builds.Unparalleled Cooling EfficiencyThe NF-A14x25 G2 delivers a significant leap in performance, excelling in all applications, whether as a case fan, on a CPU heatsink, or mounted on a liquid cooling radiator. Its state-of-the-art impeller design generates exceptional airflow and static pressure, ensuring that your components stay cool under the most demanding loads. This fan is engineered to work efficiently against back-pressure, making it the ideal solution for dense radiator fins and restrictive heatsinks, providing superior thermal headroom for overclocking and intensive tasks.Whisper-Quiet OperationNoctu´s reputation for silent cooling is elevated to a new level with the NF-A14x25 G2. Featuring an Advanced Acoustic Optimisation (AAO) frame and integrated anti-vibration pads, the fan minimizes operational noise and transfers of vibration to the PC case. The custom-designed NE-FD5 PWM IC ensures remarkably smooth motor impulses, which reduces audible clicks and allows for ultra-quiet performance, especially at low fan speeds. Enjoy a powerful system without the distracting noise.State-of-the-Art Engineering and FeaturesAt the heart of its superior performance is a revolutionary impeller design that features an exceptionally tight tip clearance of just 0.7mm. This precision engineering minimizes leakage flows, allowing the fan to work more efficiently and build higher pressure. The fan´s hub is metal-reinforced for ultimate precision and long-term stability, while Noctu´s renowned SSO2 bearing guarantees an exceptionally long lifespan and consistent, quiet operation for years to come. Full support for PWM (Pulse Width Modulation) speed control via the 4-pin connector allows your motherboard to intelligently manage fan speed, balancing cooling performance and acoustics automatically.Technical Specifications:* Size: 140x140x25 mm* Connector: 4-pin PWM* Bearing: SSO2 (Self-Stabilising Oil-pressure Bearing)* Rotational Speed (+/- 10%): 1900 RPM* Rotational Speed with L.N.A.
