Nf-A4X20 5V, High-Performance Quiet Fan 40Mm
Product description
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 ensure superb running smoothness and excellent long-term stability. Topped off with modular cabling and the OmniJoin Adaptor Set, the NF-A4x20 5V is a premium choice for demanding 5V applications.
5V version
Many devices such as network or storage solutions use 5-volt 40mm fans. With the same operating voltage and the included OmniJoin Adaptor Set that makes it compatible with proprietary fan headers, the NF-A4x20 5V is ideal for replacing noisy or broken 5V 40mm fans.
Please note: Being a 5V fan, the NF-A4x20 5V 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-A4x20 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-A4x20 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 mounting systems and fan clips used on heatsinks.

Please Note:
Being a 5V fan, the NF-A4x20 5V cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.
