Noctua NF-A4x10 FLX: Premium Quiet Cooling in a Compact 40mm Form FactorExperience the pinnacle of silent cooling performance in a highly compact package with the Noctua NF-A4x10 FLX. This premium-quality 40 mm fan is engineered for the most demanding applications where space is limited and noise is a critical factor. Whether you´re upgrading a 1U server, a network switch, a router, a DVR, or building a small form factor (SFF) PC, the NF-A4x10 FLX delivers exceptional airflow and static pressure with a sound signature that is barely audible. It stands as the ultimate cooling solution for professionals and enthusiasts who refuse to compromise on quality and silence.Key Benefits:The primary advantage of the NF-A4x10 FLX is its ability to provide robust cooling while maintaining whisper-quiet operation. Its advanced aerodynamic design ensures maximum cooling efficiency, moving a significant volume of air to protect sensitive components from overheating. The FLX (Flexibility) designation means you have complete control over performance and acoustics. Using the included Low-Noise (L.N.A.) and Ultra-Low-Noise (U.L.N.A.) adaptors, you can fine-tune the fan´s speed to achieve the perfect balance for your specific needs—from maximum performance to near-silent operation. Backed by an industry-leading 6-year manufacturer´s warranty and an MTTF rating of over 150.000 hours, this fan is a long-term investment in reliability and peace of mind.Main Features:Noctua has integrated its most advanced technologies into this 40 mm fan. The fan´s Advanced Acoustic Optimisation (AAO) frame features a Stepped Inlet Design and Inner Surface Microstructures, which work in tandem to reduce noise and improve airflow efficiency. Furthermore, Flow Acceleration Channels on the blades speed up the airflow at the crucial outer blade regions, leading to reduced vortex shedding noise and higher efficiency.At the heart of the fan is Noctu´s renowned SSO2 bearing. This second-generation, self-stabilising oil-pressure bearing guarantees superb long-term stability and exceptional quietness throughout its extensive lifespan. For maximum compatibility, the NF-A4x10 FLX includes an OmniJoin™ Adaptor Set, allowing it to be easily connected to proprietary fan headers found in many non-PC devices. Integrated anti-vibration pads and included silicone anti-vibration mounts prevent the transfer of minute vibrations, further ensuring a silent and stable installation.Technical Specifications:* Size: 40x40x10 mm* Connector: 3-pin* Bearing: SSO2* Rotational Speed (Standard): 4500 RPM* Rotational Speed (with L.N.A.): 3700 RPM* Rotational Speed (with U.L.N.A.): 3000 RPM* Airflow (Standard): 8.2 m³/h* Airflow (with L.N.A.): 6.6 m³/h* Airflow (with U.L.N.A.): 4.9 m³/h* Acoustical Noise (Standard): 17.9 dB(A)* Acoustical Noise (with L.N.A.): 12.9 dB(A)* Acoustical Noise (with U.L.N.A.): 8.5 dB(A)* Static Pressure: 1.78 mm H₂O* Max.
