Noctua NF-A14 - Computer case - Fan - 14 cm - 300 RPM - 1500 RPM - 24.6 dB (NF-A14 5V PWM)
The NF-A14 5V PWM is a PWM-enabled 5V variant of Noctua’s award-winning, premium-quality NF-A14 140mm fan. Featuring an AAO (Advanced Acoustic Optimisation) standard frame and sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A14 is renowned for its superior performance and outstanding quietness of operation. Smooth Commutation Drive technology and Noctua’s reference class SSO2 bearing guarantee superb running smoothness and excellent long-term stability. Topped off with the included USB power adaptor cable, OmniJoin™ adaptor set and 6-year manufacturer’s warranty, the NF-A14 5V PWM is a premium choice for demanding 5V applications that require PWM control.Being a 5V fan, the NF-A14 5V PWM cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.Award-winning NF-A14 designHaving received more than 100 awards and recommendations from the international press, Noctua's NF-A14 has become a proven premium choice for 140mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world.5V PWM version5V fans are used in various devices and applications. With the included USB power adaptor cable and OmniJoin™ adaptor set, the NF-A14 5V PWM is a proven premium solution that gives you full flexibility both for replacing existing 5V fans and for new, custom applications.Flow Acceleration ChannelsThe NF-A14 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 screws and other mounting systems.Custom-designed PWM IC with SCDSupporting fully automatic PWM speed control, the NF-A14 5V PWM uses Noctua's novel, custom-designed NE-FD3 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.Polarity protectionAs many devices using 5V fans feature proprietary connectors, and documentation of the pin alignment may not be available, the fan features an integrated diode for polarity protection. This way, you're on the safe side if you accidentally connect it with reverse polarity.SSO2 BearingThe NF-A14 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.Metal bearing shellIn order to guarantee the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the NF-A14 sports a CNC milled bearing shell made entirely from brass.OmniJoin™ Adaptor SetMany devices featuring 5V fans use proprietary fan headers, so the NF-A14 5V PWM 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 yo
