The FLX version provides 5000\/4400\/3700rpm speed settings via the supplied Low-Noise Adaptors and includes the OmniJoin™ Adaptor Set for easy connection to proprietary fan headers. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.\u003cbr\u003e\u003cbr\u003e40x20mm size\u003cbr\u003eCompared to Noctua’s award-winning NF-A4x10, the NF-A4x20 is twice as thick, which allows for increased static pressure performance and makes the NF-A4x20 ideal for demanding applications with high flow resistance.\u003cbr\u003e\u003cbr\u003eFlow Acceleration Channels\u003cbr\u003eThe NF-A4x20 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.\u003cbr\u003e\u003cbr\u003eAAO Frame\u003cbr\u003eNoctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan's performance\/noise efficiency.\u003cbr\u003e\u003cbr\u003eStepped Inlet Design\u003cbr\u003eNoctua's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space-restricted environments.\u003cbr\u003e\u003cbr\u003eInner Surface Microstructures\u003cbr\u003eWith the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.\u003cbr\u003e\u003cbr\u003eIntegrated Anti-Vibration Pads\u003cbr\u003eIntegrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.\u003cbr\u003e\u003cbr\u003eSmooth Commutation Drive 2\u003cbr\u003eThe latest version of Noctua's advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the fan remarkably quiet even at very close distances.\u003cbr\u003e\u003cbr\u003eSSO2 bearing\u003cbr\u003eThe NF-A4x20 features the further optimised second generation of Noctua's renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.\u003cbr\u003e\u003cbr\u003e3 speed settings for full flexibility\u003cbr\u003eProviding 5000, 4400 and 3700 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the NF-A4x20 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eOmniJoin™ adaptor set\u003cbr\u003eMany devices featuring 40mm fans use proprietary fan headers, so the NF-A4x20 comes with Noctua's OmniJoin™ adaptor set. Just cut the original fan's cable, fix it to the adaptor using the supplied 3M Scotchlok™ connectors and you can plug the NF-A4x20 to proprietary fan headers!\u003cbr\u003e\u003cbr\u003eExtensive cabling options\u003cbr\u003eThe fan's short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and the supplied 3:4 pin adaptor allows the connection of the fan directly to the power supply.\u003cbr\u003e\u003cbr\u003e6-year manufacturer’s warranty\u003cbr\u003eNoctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A4x20 features an MTTF of more than 150.000 hours rating and comes with a full 6-year manufacturer’s warranty.\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable class=\"generic\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003ePerformance\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable location\u003c\/td\u003e\n\u003ctd\u003eComputer case\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFan connector\u003c\/td\u003e\n\u003ctd\u003e3-pin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRotational speed (min)\u003c\/td\u003e\n\u003ctd\u003e3700 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRotational speed (max)\u003c\/td\u003e\n\u003ctd\u003e5000 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRotational speed with LNA (max)\u003c\/td\u003e\n\u003ctd\u003e4400 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNoise level with LNA (max)\u003c\/td\u003e\n\u003ctd\u003e12.2 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAirflow with LNA (max)\u003c\/td\u003e\n\u003ctd\u003e8.3 m³\/h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBearing type\u003c\/td\u003e\n\u003ctd\u003eSelf-Stabilising Oil-pressure Bearing (SSO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMean time to failure (MTTF)\u003c\/td\u003e\n\u003ctd\u003e150000 h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNoise level (low speed)\u003c\/td\u003e\n\u003ctd\u003e8.5 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNoise level (high speed)\u003c\/td\u003e\n\u003ctd\u003e14.9 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eFan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFan diameter\u003c\/td\u003e\n\u003ctd\u003e4 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported processor sockets\u003c\/td\u003e\n\u003ctd\u003eNot supported\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible processor series\u003c\/td\u003e\n\u003ctd\u003eNot supported\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum air pressure\u003c\/td\u003e\n\u003ctd\u003e1.23 mmH2O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum air pressure\u003c\/td\u003e\n\u003ctd\u003e2.26 mmH2O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAirflow\u003c\/td\u003e\n\u003ctd\u003e9.4 m³\/h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting hole pattern (W x D)\u003c\/td\u003e\n\u003ctd\u003e32 x 32 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003eDesign\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFan connector\u003c\/td\u003e\n\u003ctd\u003e3-pin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct colour\u003c\/td\u003e\n\u003ctd\u003eBeige, Brown\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003eTechnical details\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNoise level (low speed)\u003c\/td\u003e\n\u003ctd\u003e8.5 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNoise level (high speed)\u003c\/td\u003e\n\u003ctd\u003e14.9 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eFan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFan diameter\u003c\/td\u003e\n\u003ctd\u003e4 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported processor sockets\u003c\/td\u003e\n\u003ctd\u003eNot supported\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible processor series\u003c\/td\u003e\n\u003ctd\u003eNot supported\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum air pressure\u003c\/td\u003e\n\u003ctd\u003e1.23 mmH2O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum air pressure\u003c\/td\u003e\n\u003ctd\u003e2.26 mmH2O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAirflow\u003c\/td\u003e\n\u003ctd\u003e9.4 m³\/h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFan connector\u003c\/td\u003e\n\u003ctd\u003e3-pin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting hole pattern (W x D)\u003c\/td\u003e\n\u003ctd\u003e32 x 32 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003cth colspan=\"2\" class=\"text-left\"\u003ePorts \u0026amp;
