Product description
The NF-A9 5V PWM is a PWM-enabled 5V variant of Noctua’s award-winning, premium-quality NF-A9 92mm fan. Featuring an AAO (Advanced Acoustic Optimisation) standard frame and sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A9 is renowned for its superior performance and outstanding quietness of operation. Smooth Commutation Drive technology and Noctua’s reference class SSO2 bearing ensure superb running smoothness and excellent long-term stability. Topped off with the included USB power adaptor cable and OmniJoin adaptor set, the NF-A9 5V PWM is a premium choice for demanding 5V applications that require PWM control.
5V PWM version
5V PWM fans are used in various devices and applications. With the included USB power adaptor cable and OmniJoin adaptor set, the NF-A9 5V PWM is a proven premium solution that gives you full flexibility both for replacing existing 5V PWM fans and for new, custom applications that require PWM speed control.
Please Note: Being a 5V fan, the NF-A9 5V PWM cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.
Flow Acceleration Channels
The NF-A9 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.
SSO2 bearing
The NF-A9 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.
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.
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!
Please Note:
Being a 5V fan, the NF-A9 5V PWM cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.
