Noctua NF-A4x10 5V PWM: Premium Quiet Cooling for 40mm ApplicationsExperience the pinnacle of silent cooling performance in a compact form factor with the Noctua NF-A4x10 5V PWM. This highly optimised, premium-quality 40 mm fan is engineered for demanding 5V applications, delivering exceptional airflow and static pressure with whisper-quiet operation. It stands as the ideal upgrade for noisy or failing fans in network devices, storage solutions, 3D printers, single-board computers (like Raspberry Pi), and other specialised electronics that utilise a 5V, 4-pin PWM fan header.The NF-A4x10 5V PWM is not just a standard PC fan, it is a specialised solution built on Noctu´s legacy of award-winning design. Its compact 40x10 mm size makes it perfect for space-constrained environments where performance and acoustics cannot be compromised. By integrating a custom-designed NE-FD3 PWM IC that supports fully automatic speed control, this fan allows your device to intelligently adjust cooling power, ensuring it runs silently at idle and provides maximum performance only when needed.Key Benefits:* Superior Acoustic Performance: Drastically reduce the operational noise of your equipment. The fan´s advanced aerodynamic design features, including Flow Acceleration Channels and an AAO frame, ensure it moves more air while generating significantly less noise than conventional fans.* Exceptional Longevity and Reliability: Built with Noctu´s renowned SSO2 bearing, the NF-A4x10 5V PWM guarantees superb long-term stability and a Mean Time To Failure (MTTF) of over 150.000 hours. This is a true set it and forget it upgrade, backed by a full 6-year manufacturer´s warranty.* Versatile 5V PWM Control: Specifically designed for 5V environments, this fan provides precise speed regulation from 1000 to 5000 RPM. This allows for a perfect balance between near-silent operation and high-performance cooling, tailored to the real-time needs of your device.* Universal Compatibility: Worried about proprietary connectors? The included OmniJoin™ Adaptor Set allows you to easily and safely connect the fan to non-standard fan headers, making it a versatile replacement for a wide range of devices.Main Features:* Advanced Acoustic Optimisation (AAO) Frame: Features integrated anti-vibration pads and Noctu´s Stepped Inlet Design and Inner Surface Microstructures to further refine the fan´s performance and noise signature.* Flow Acceleration Channels: These channels on the suction side of the blades speed up airflow at the crucial outer blade regions, reducing flow separation and leading to higher efficiency and lower vortex noise.* SSO2 Bearing: Noctu´s second-generation, self-stabilising oil-pressure bearing places the rear magnet closer to the axis, delivering even better precision, stability, and durability.* Custom-Designed 5V PWM IC: The integrated NE-FD3 PWM driver IC provides excellent energy efficiency and allows for smooth, fully automatic speed control via the 4-pin header.* Low-Noise Adaptor (L.N.A.): For users seeking the quietest possible operation, the included L.N.A. cable reduces the maximum fan speed from 5000 to 3700 RPM.Technical Specifications:* Size: 40x40x10 mm* Connector: 4-pin PWM* Bearing: SSO2* Rotational Speed (+/- 10%): 5000 RPM* Rotational Speed with L.N.A.
