Noctua G2 140mm Premium Quality Quiet PC Connection NF-A14x25 PWM, Fan, 4-Pin (Brown)

We offer a wide variety of products, and the following precautions apply to some of them. Please note that they are listed for all products. 【Voltage Compatibility】Designed for Japanese voltage (90-110V). Using with a different voltage may cause malfunction. 【Plug Type】Japanese plugs (A or B type). Use a conversion adapter if needed. 【Transformers & Adapters】Transformers adjust voltage; adapters only change plug shape. Using an adapter without a transformer may damage the product. 【Liability】We are not responsible for damages caused by improper use, such as using the product without a transformer. Next-generation 140x25mm design delivers unprecedented silent cooling performance in both high airflow and high static pressure environments: perfect for PC case fans, CPU coolers, and water cooling radiators! State-of-the-art engineering (progressive bend impeller with winglets, centrifugal turbulators, flow acceleration channels, and AAO frame) and construction (Sterrox LCP, ultra-close tip clearance) 4-pin PWM version for automatic speed control via 4-pin PWM motherboard fan header, speed range from 300 to 1500 rpm (almost silent at idle, powerful performance under load), fan shuts off at 0% PWM (semi-passive option) Includes anti-vibration mount, 14cm anti-vibration gasket to strengthen sealing of radiators, etc., fan screws, low noise adapter (LNA), extension cable, and Y cable to run two PWM fans on the same header. Reliable Noctua quality with premium level SSO2 bearings (MTTF＞150,000 hours), UL and TÜV safety certifications, reverse polarity, overvoltage and overcurrent (short circuit) protection Inheriting the award-winning NF-A14 and building on the breakthrough innovations of the NF-A12x25, the NF-A14x25 G2 is Noctua's next generation square frame 140mm flagship model. : Combining Sterrox LCP manufacturing, a progressive bend impeller with highly optimized winglets, flow acceleration channels, centrifugal turbulator hub and just 0.7mm tip socket, the NF-A14x25 G2 further improves on the excellent silent cooling performance of its predecessor. Like the NF-A14 and NF-A12x25, it delivers excellent results in all types of use, whether in low impedance, airflow oriented environments such as case cooling, or high impedance static pressure requirements such as heat sinks and cooling radiators. For environment-specific optimization, the NF-A14x25 G2 comes pre-installed with an NA-AVG2-LR anti-vibration gasket for better adhesion to the radiator. In addition, the AAO (Advanced Acoustic Optimization) frame can be added to the optional NA -Can also be combined with IS1-14 inlet spacer. The 4-pin PWM version supports fully automatic speed control with a PWM fan header and comes with a low-noise adapter to reduce the maximum speed from 1500rpm to 1250rpm. The ultra-low-loss etaPERF motor with Smooth Commutation Drive 2 technology delivers unprecedented energy efficiency and smooth operation, while the new SupraTorque feature leverages additional torque headroom to keep fans at the right speed against backpressure, further improving performance on heatsinks, radiators, and more. The NF-A14x25 G2 is a top quality product with Noctua's reference class SSO2 bearings, extensive accessory bundle, and 6-year manufacturer warranty. Its superior performance, comprehensive features and cutting-edge construction and materials set a new standard in Noctua's portfolio, making it the perfect choice for the most discerning demands.
