Noctua NA-SRC7 computer cooling system part/accessory

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).
