For powering and speed-controlling three fans through a single fan header
Supports both 3-pin and 4-pin PWM fans
Forwards the PWM signal for speed control to all 3 output connectors
The NA-SC1 splitter cables not only come in handy when building or upgrading PCs (e.g. if you want to control the fans on your 360mm radiator through a single header or if you add extra case fans and don’t have any free headers), but also in home and multi-purpose ventilation applications such as when powering several fans on a heating radiator through a single NV-PS1 power supply.
The NA-SC1 1-to-3 splitter cables forward the PWM signal for speed control from the input connector to all 3 output connectors. They also transfer the RPM speed signal of one fan (output connector 1) back to the input connector for speed monitoring through the motherboard or other fan controllers (due to the signal specifications, only one fan per port can be monitored).
The NA-SC1 cables feature a 4-pin connector that works with both 3-pin and 4-pin PWM fans. As such, the cables are fully compatible with all current Noctua 5V, 12V and 24V fans as well as many third-party models. Additionally, thanks to the keyed design of the connector, there is no risk of misaligning 3-pin fans.
The NA-SC1 cables come with Noctua’s signature braided fibreglass sleeving with silicone coating that is highly resistant against mechanical wear as well as heat and flames (up to 200°C, UL 1441 certified). As such, the NA-SC1 cables are suitable for use in critical applications and harsh industrial environments.
