The NF-A14 5V is a specific 5V version of the famous high-end 140mm Noctua NF-A14 fan. Built around the traditional AAO (Advanced Acoustic Optimisation) frame and benefiting from the latest aerodynamic technology (such as Flow Acceleration Channels), the NF-A14 has built a solid reputation for its superior performance and unparalleled operational silence. The Tecnología Smooth Commutation Drive technology combined with the Noctua SSO2, a true reference for the bearing, allow for an exceptional level of stability over the long term as well as an incredibly flexible operation. Supplied with a USB power adapter, OmniJoin adapter kit and backed by a 6-year manufacturer's warranty, the NF-A14 5V is the go-to solution for demanding 5V configurations. As a 5v fan, the NF-A14 5V cannot operate under 12V; supplying it via a current source generating such a voltage (this is the case of the ventilation connectors present on the motherboards) would inevitably damage it.
