The NA-RC6 is a fan accessory set consisting of three fully sleeved NA-RC6 Low Noise Adaptors (LNA) for Noctua 4-pin PWM fans. Connected between the fan and the power source, the adaptors reduce the running speed and noise emission of the fans. The NA-RC6 is ideal for slowing down Noctua’s (brown/tan) fans.

Never use one Low-Noise Adaptor to slow down multiple fans. Always use one adaptor per fan.

The NA-RC6 adaptors are NOT compatible with 5V fans and Noctua’s industrial PPC or redux series.

The NA-RC6 adaptor is designed for use with all Noctua 4-pin fans (except industrial PPC & redux series). While it may work with many other fans, use with third party fans is not officially supported by Noctua, is at the customer’s own risk and will void the warranty. The NA-RC6 adaptor is strictly not to be used with fans that draw more than 2.5W of power.
