4. Utilize Low-Noise Adaptors (Optional): To reduce the fan speed and noise level, connect one of the supplied Low-Noise Adaptors (L.N.A. or U.L.N.A.) between the fan's 3-pin connector and the fan header.
   • L.N.A. (NA-RC10): Reduces speed to 4400 RPM.
   • U.L.N.A. (NA-RC12): Reduces speed to 3700 RPM.
5. OmniJoin™ Adaptor Set: If your device uses a proprietary fan header, use the OmniJoin™ Adaptor Set (NA-RC14) to connect the fan. This set allows you to adapt the fan's standard 3-pin connector to various proprietary pin-outs. Refer to the OmniJoin™ instructions for specific wiring details.
6. Kabllo shtese: Use the provided extension cable if the fan's cable is not long enough to reach the desired fan header.

5. Operacioni

Once installed and connected, the Noctua NF-A4x20 FLX fan will operate automatically when power is supplied to the fan header. The fan's speed will depend on whether a Low-Noise Adaptor is used:

• Without Adaptor: The fan operates at its maximum speed of 5000 RPM.
• With L.N.A. (NA-RC10): The fan operates at 4400 RPM.
• With U.L.N.A. (NA-RC12): The fan operates at 3700 RPM.

Select the appropriate adaptor based on your preference for airflow versus noise level. Higher RPMs provide more airflow and cooling, while lower RPMs result in quieter operation.
