## Summary description

Noctua NA-SC1 Sx2 is a pack of two 3-way 4-pin PWM fan splitter cables designed to connect up to three PWM fans to a single motherboard header. Each splitter preserves PWM control from the header, enabling synchronized speed management and simplified cable routing inside PC cases. Suitable for cooling setups needing multiple fans on one header.

## Long description

Noctua NA-SC1 Sx2 is a pack of two 3-way 4-pin PWM fan splitter cables that let you connect up to three PWM fans to a single motherboard header. Each splitter keeps the PWM signal intact so fan speed control and automatic regulation from the motherboard work for all connected fans. The compact cables simplify cable routing inside the PC case and are intended for systems where multiple fans must be controlled from one header.
Advantages
The splitter cables preserve PWM control for all connected fans, enabling synchronized speed adjustment and automatic thermal management. Compact, flexible wiring reduces clutter and improves airflow by minimizing loose cables. The 4-pin connectors maintain proper power delivery and control signals, while the pack of two provides options for multiple fan groups in a single system.
Suitable for
Expanding a single motherboard PWM header to power and control three PWM fans
Systems with limited fan headers on the motherboard
Multi-fan intake or exhaust setups in PC cases
Small form-factor builds where cable routing must be optimized
Key specifications
Connector type: 4-pin PWM female to three 4-pin PWM male outputs
Configuration: 1-to-3 splitter per cable
Quantity: pack of two splitter cables
Signal support: PWM speed control preserved to all outputs
Cable design: compact and flexible wiring for internal PC routing
How to use
Plug the female 4-pin connector of one splitter into the motherboard PWM fan header. Connect up to three PWM fans to the male 4-pin outputs. The motherboard will send the PWM signal through the splitter so all attached fans follow the same speed control profile. Repeat the process with the second splitter if you need to expand another header. Ensure that the combined current draw of connected fans does not exceed the motherboard header's specifications; when necessary, distribute fans across multiple headers or use a powered hub.
Usage recommendations
Use the splitters for synchronised fan control when fans share similar airflow and static pressure characteristics. Verify motherboard header current limits in the manual and avoid overloading a single header with high-power fans. Keep cables tidy and away from moving components to maintain airflow and safety.
