The NF-A4x10 5V case fan from Noctua is characterized by its high operational quietness, with a maximum noise level of 17.9 dB(A), achieved through Smooth Commutation Drive technology and SSO2 reference-class bearings. The fan connects via a 3-pin connector and is modularly wired. Additionally, you receive a 3:2 pin adapter, an OmniJoin adapter set, and a 30 cm cable extension for optimal connectivity. The NF-A4x10 5V delivers excellent cooling performance with a speed of 4500 rpm, generating an airflow of up to 8.2 m³/h. For reliable cooling, the fan is also equipped with four vibration compensators. The design of the NF-A4x10 5V fan is based on an AAO frame system, which is known for its balanced performance-noise efficiency, as well as Flow Acceleration Channel fan blades, whose airflow channels on the intake side accelerate airflow in the outer blade regions.
