## Description

Features: Size (Form factor): 140 x 140 x 25 mm (square) Speed range: 0 – 1500 rpm Airflow (max.): 140.2 m³/h (82.52 CFM) Acoustical noise (max.): 24.6 dB(A) Static pressure (max.): 2.08 mm H₂O Rated voltage: 5 V Input power (typical): 0.99 W Connector: 4 Pin Frame shape: Square Mounting hole spacing(s): 124.5 x 124.5 mm Material frame: PBT GF30 Material impeller: PBT GF30 Material anti-vibration pads: Silicone rubber Bearing: SSO2 Rotational direction: Counter-clockwise Connector type: A2543-4PIN (or equal) Wire: 26 AWG Sleeving: Fibreglass silicone mesh Rotational speed (max.): 1500 rpm Rotational speed @ 20% PWM: 400 rpm Acoustical noise (max.): 24.6 dB(A) Airflow (max.): 140.2 m³/h (82.52 CFM) Static pressure (max.): 2.08 mm H₂O Award-winning NF-A14 design Having 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 version 5V 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 Channels The 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 frame Noctua'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 Design Noctua'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 Microstructures With 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 pads Integrated 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 SCD Supporting 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 protection As 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 Bearing The 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 shell In 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.
