Noctua Noctua NF-A14x25 G2 LS-PWM Fan - 140mm

- 140 mm PWM fan with very good price-performance ratio - Cooling by 800 revolutions per minute - High airflow and static pressure - Very low noise level of only 11.4 dB(A) at full load - LCP material has many advantages NF-A14x25 G2 LS: Good performance at an unbeatable price Noctua is known for its high-quality fans: The NF-A14x25 G2 LS impresse... mores not only with its excellent price-performance ratio, but also with its materials. Powerful cooling thanks to high-end materials With its 800 revolutions per minute, your components are kept at low temperatures. Due to the relatively low yet sufficient number of revolutions, the fan is particularly quiet: it reaches just 11.4 dB(A) under full load. You also get a low-noise adapter with the fan. This reduces the fan's maximum speed to 600 rpm, making it significantly quieter at 8.6 dB(A). You can choose whether you prefer faster revolutions or a quieter noise level. The NF-A14x25 G2 LS 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 LS uses Noctua's proprietary SSO2 bearing . This reduces noise and increases stability, while also increasing the longevity of the fans.

Noctua NF-A14X25.G2.LS

Upgrade your PC´s cooling performance with the Noctua NFA14 G2, a premium-quality, low-speed 140 mm PWM fan engineered for quiet operation and superior airflow. This second-generation model builds upon Noctu´s renowned reputation for exceptional cooling solutions, delivering enhanced performance and durability for demanding PC builds, case cooling,... moreand radiator applications. Experience whisper-quiet operation without compromising on cooling efficiency.The Noctua NFA14 G2 140 mm fan utilizes the advanced Sterrox® liquid-crystal polymer (LCP) material in its impeller, contributing to exceptional tensile strength, dimensional stability, and low thermal expansion. This allows for tighter tip clearances and minimizes blade deformation under high RPM, resulting in improved airflow and reduced noise levels. The fan also features Noctu´s SSO2 bearing, a second-generation self-stabilizing oil-pressure bearing system that ensures long-term reliability and smooth operation. This advanced bearing technology contributes to the fan´s impressive Mean Time Between Failures (MTBF) rating, ensuring years of dependable performance.Designed for fine-tuned control, the NFA14 G2 integrates Pulse Width Modulation (PWM) technology, allowing for dynamic speed adjustments based on system temperature. This ensures optimal cooling performance while minimizing noise output. The included Low-Noise Adaptor (L.N.A.) further reduces the maximum speed and noise levels, making the NFA14 G2 ideal for noise-sensitive applications. Connect the fan directly to your motherboard´s 4-pin PWM header and let your system automatically regulate the fan speed for optimal cooling efficiency.The aerodynamically optimized design of the NFA14 G2 140 mm fan, including Flow Acceleration Channels and Inner Surface Microstructures, contributes to its exceptional performance. These features enhance airflow and reduce turbulence, maximizing cooling potential while minimizing noise. The fan´s robust construction and high-quality materials ensure long-term durability and resistance to wear and tear.Technical Specifications:* Size: 140x140 x 25 mm* Bearing: SSO2* Blade Geometry: A-Series with Flow Acceleration Channels* Rotational Speed (+/- 10%): 1200 RPM (with L.N.A.: 900 RPM)* Minimum Rotational Speed (PWM, +/-20%): 300 RPM* Airflow: 115.5 m³/h (with L.N.A.: 82.5 m³/h)* Acoustic Noise: 24.6 dB(A) (with L.N.A.: 18.6 dB(A))* Static Pressure: 1.53 mm H₂O (with L.N.A.: 0.84 mm H₂O)* Input Power: 1.56 W (with L.N.A.: 0.6 W)* Maximum Input Current: 0.13 A (with L.N.A.: 0.05 A)* Voltage: 12 V* MTBF: > 150.000 h* Included Accessories: Low-Noise Adaptor (L.N.A.), 4 vibration-compensators, 4 fan screwsThe Noctua NFA14 G2 140 mm fan is the perfect choice for users seeking a quiet and efficient cooling solution for their PC. Whether you´re building a high-performance gaming rig, a silent home theater PC, or simply upgrading your existing system, the NFA14 G2 delivers exceptional performance and
