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. 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. 40x20mm size Compared to Noctua's award-winning NF-A4x10, the NF-A4x20 is twice as thick, which allows for increased static pressure performance and makes the NF-A4x20 ideal for demanding applications with high flow resistance. 5V version Many devices such as network or storage solutions use 5-volt 40mm fans. With the same operating voltage and the included OmniJoinTM Adaptor Set that makes it compatible with proprietary fan headers, the NF-A4x20 5V is ideal for replacing noisy or broken 5V 40mm fans. 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.
