Product Description

Manufacture # Noctua | Model # A4x20-5V

 

Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A4x20 5V is a dedicated 5V version of Noctua’s highly optimised, premium quality quiet 40x20mm fan. Smooth Commutation Drive technology and Noctua’s reference class SSO2 bearings guarantee superb running smoothness and excellent long-term stability. Topped off with modular cabling, the OmniJoin Adaptor Set and 6 years manufacturer’s warranty, the NF-A4x20 5V is a premium choice for demanding 5V applications.

 

Features:

  • The NF-A4x20-5V is twice as thick, which allows for increased static pressure performance and makes 
  • The NF-A4x20-5V ideal for demanding applications with high flow resistance
  • Many devices such as network or storage solutions use 5 volt 40mm fans with PWM speed control
  • The same operating voltage, PWM support and the included OmniJoin™ adaptor set
  • The NF-A4x20 5V PWM is ideal for replacing noisy or broken 5V 40mm fans with PWM
  • As many devices using 5V fans feature proprietary connectors and documentation
  • The fan features an integrated diode for polarity protection
  • The NF-A4x20-5V impeller features suction side Flow Acceleration Channels
  • Noctua’s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads
  • Noctua’s Stepped Inlet Design adds turbulence to the influx in order to facilitate
  • The tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures
  • Integrated Anti-Vibration Pads made from extra-soft silicone minimise.
