Product details

The NF-A4x20 5V is a special 5V version of Noctua's 40x20mm premium fan, utilizing the AAO frame system and advanced aerodynamic design measures such as Flow Acceleration Channels. The Smooth Commutation Drive technology and the reference-class SSO2 bearing ensure excellent smoothness and outstanding long-term stability. Modular cabling, the OmniJoin adapter set, and a 6-year manufacturer's warranty make the NF-A4x20 5V a premium solution for demanding 5V applications. As a 5V fan, the NF-A4x20 5V cannot be operated with 12V. Connecting it to common 12V power sources, such as fan headers on PC motherboards, will damage the fan.
