Noctua NA-SRC7 4-Pin PWM Low-Noise Adaptors 3 pack NA-SRC7

The NA-SRC7 is a fan accessory set consisting of three fully sleeved NA-RC7 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-SRC7 is ideal for slowing down Noctua's redux edition fans (see speed tables).

Please note the following when using this product. Never use one Low-Noise Adaptor to slow down multiple fans. Always use one adaptor per fan.
The NA-RC7 adaptors are not compatible with Noctua's industrialPPC series.
The NA-RC7 adaptor is designed for use with Noctua 4-pin fans (except industrialPPC series). While it may work with many other fans; use with third party fans is not officially supported by Noctua; it is at the customer's own risk and will void the warranty. The NA-RC7 adaptor is strictly not to be used with fans that draw more than 3W of power.
