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 SSO2bearing assure superb running smoothness and excellent long-term stability. Topped off with the included USB power adaptor cable and OmniJoin adaptor set, the NF-A14 5V PWM is a premium choice for demanding 5V applications that require PWM control.
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.
Please Note: 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.
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.
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.
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.
USB power adaptor cable
The fan includes a USB power adaptor cable that allows it to run on power banks, devices with USB host ports or USB power supplies such as those used for smartphones.
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.
