Noctua NF-A14X25R G2 PWM

Experience the pinnacle of quiet cooling technology with the NOCTUA NF-A14x25r G2 PWM, the next-generation 140 mm fan engineered for ultimate performance. As a successor to Noctu´s legendary and award-winning models, this fan sets a new benchmark in static pressure, airflow, and near-silent operation, making it the definitive choice for enthusiasts... morewho demand the very best for their high-end PC builds. Whether used as a computer case fan or for optimizing a CPU cooler, its advanced design delivers a superior thermal solution.The NF-A14x25r G2 PWM achieves its remarkable efficiency through state-of-the-art aerodynamic engineering. A key innovation is the exceptionally tight tip clearance, which dramatically reduces airflow leakage between the blade tips and the frame. This results in a more focused and powerful airstream, generating impressive airflow of up to 155.6 m³/h and the high static pressure needed to effectively cool dense heatsink fins and water-cooling radiators. This fan is built to perform under pressure, ensuring your components stay cool during the most intensive tasks.Engineered for whisper-quiet acoustics, the fan operates at a barely audible 19.7 dB at lower speeds. At its maximum rotational speed of 1500 RPM, it maintains an impressively low noise profile. This quiet performance is powered by the renowned SSO2 bearing technology, which ensures exceptional running smoothness and long-term stability. The integrated 4-pin PWM connector allows for precise, automatic speed control via your motherboard, dynamically balancing cooling power and silence. For users prioritizing absolute quiet, the included Low-Noise Adaptor (LNA) offers an even quieter operational mode.Designed for longevity and uncompromising stability, this 140 mm fan features a structure of advanced Liquid Crystal Polymer (LCP). This material provides extreme rigidity and low thermal expansion, allowing for the fan's precision-critical design and reliable performance over its entire lifespan. This robust construction contributes to an outstanding Mean Time To Failure (MTTF) of 150.000 hours, backed by a comprehensive 6-year warranty for complete peace of mind. The round frame design with a 105x105 mm mounting hole pattern makes it an ideal upgrade for many CPU coolers originally designed for 120 mm fans, providing a significant boost in cooling capability.Technical SpecificationsBearing technology:SSO2.Warranty period:6 year(s).Material:Liquid Crystal Polymer (LCP).Fan connector:4-pin.Number of fans:1 fan(s).Maximum current:0.19 A.Voltage:12 V.Fan dimensions (W x D x H):140x25 x 140 mm.Noise level (low speed):19.7 dB.Airflow:155.6 m³/h.Type:Fan.Bearing type:Self-Stabilising Oil-pressure (SSO) bearing.Rotational speed (max):1500 RPM.Rotational speed (min):1250 RPM.Fan diameter:14 cm.Noise level (high speed):24.8 dB.Suitable location:Computer case.Screws included:Yes.Low-noise adaptor (LNA):Yes.Mounting hole pattern (W x D):105x105 mm.Mean time to failure
