• The NF-A8 5V is a dedicated 5V version 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 is a premium choice for demanding 5V applications.

  • Being a 5V fan, the NF-A8 5V cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.

If you replace an existing fan, it is usually best to use the screws (or other mounting mechanisms) used for the original fan.

Being a 5V fan, the NF-A8 5V can not be run at 12V and will be damaged when used with typical 12V power sources such as PC mainboard fan headers.
Depending on the application, it may also be possible to use the supplied mounting screws or silicone anti-vibration mounts.
For installing the fan using the NA-AV1 anti-vibration mounts, please first pull the mounts through the mounting holes of the case.


5V 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 is a proven premium solution that gives you full flexibility both for replacing existing 5V fans and for new, custom applications.


Award-winning NH-U9S cooler

Award-winning NF-A8 design
Having received dozens of 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 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.



Smooth Commutation Drive 2
The latest version of Noctua's advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises.
This makes the NF-A8 remarkably quiet even at very close distances.



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 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 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
With many heatsinks, the fins are press-fitted to the heatpipes.
Due to the different thermal expansion coefficients of copper and aluminium, this fit can loosen over years of thermal cycling, which may lead to reduced performance.
By contrast, the NH-U9S’s fins are soldered to the heatpipes in order to guarantee a superior thermal interface that doesn’t deteriorate even after many years of usage.


6-year manufacturer’s warranty

Do not connect to a 12V output connector.
This fan is rated at 5V, so connecting it to a 12V connector will damage the fan.
Please note that fan connectors for general PC motherboards have 12V specifications.

*Some AMD mainboards violate the 96x114mm keep-out zone specified by AMD, so the NH-U9S can only be used with RAM modules of up to 30mm height on these boards.
Please consult our compatibility list for details.
