The NF-A8 5V PWM is a PWM-enabled 5V variant of Noctua’s award-winning, premium-quality NF-A8 80mm fan.
Featuring an AAO (Advanced Acoustic Optimisation) standard frame and sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A8 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-A8 5V PWM is a premium choice for demanding 5V applications that require PWM control.
PLEASE NOTE: Being a 5V fan, the NF-A8 5V PWM cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.
Popular with Raspberry Pi users!
As it's a 5V PWM fan, we've seen a few Raspberry Pi owners hack the NF-A8 5V PWM into their custom cooling setups for their projects! For example, here's a pretty cool 3D Printed case for the Raspberry Pi 5 that uses this exact model! (have a Google, there are many more examples out there).
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-A8 5V PWM is a proven premium solution that gives you full flexibility both for replacing existing 5V fans and for new, custom applications.
Award-winning NF-A8 design
Having received more than 100 awards and recommendations from the international press, Noctua’s NF-A8 has become a proven premium choice for 80mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world.
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 DesignStepped 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-A8 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-A8 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.
OmniJoin adaptor set
Many devices featuring 5V fans use proprietary fan headers, so the NF-A8 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 you can plug the NF-A8 5V PWM to proprietary fan headers!
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, giving you near endless possibilities for using the fan in your home, in your car or wherever a need for cooling occurs!
Extensive cabling options
The 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.
6-year manufacturer’s warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A8 features an MTTF of more than 150,000 hours rating and comes with a full 6-year manufacturer’s warranty.
