Noctua NF-A4x20 PWM Computer case Fan 4 cm Beige. Brown
Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame. the NF-A4x20 is a highly optimised. premium-quality quiet fan in size 40x20mm. The PWM version sports Noctua’s custom-designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise Adaptor as well as an 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.40x20mm sizeCompared 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.Flow Acceleration ChannelsThe 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.AAO FrameNoctua'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.Stepped Inlet DesignNoctua'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.Inner Surface MicrostructuresWith 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.Integrated Anti-Vibration PadsIntegrated 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.SSO2 bearingThe 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.Custom-designed PWM IC with SCDSupporting fully automatic PWM speed control. the fan uses Noctua's custom-designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses. SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.Low-Noise AdaptorThe NF-A4x20 PWM is supplied with a (L.N.A.) that reduces the maximum fan speed from 5000 to 4400rpm. The L.N.A. can be used either to run the fan at a fixed speed of 4400rpm or to cap the maximum speed when using automatic PWM control.OmniJoin™ adaptor setMany 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!Extensive cabling optionsThe 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 a 4-pin y-cable allows the connection of a second fan to the same PWM fan header for automatic control.6-year manufacturer’s warrantyNoctua 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.
