Key Features
- Dual Fan Connection: This PC fan splitter Y cable connects 2 computer case fans to a single motherboard fan header. This 1 to 2 case fan splitter is ideal for adding an extra fan to boost airflow inside your computer case.
- 4-Pin Fan Header Support: Mobo 4 pin fan splitter connects to the 4-pin header on your motherboard and splits the PWM signal to 2 PWM fans. Both fans can spin at the same speed using motherboard software with PWM control support.
- Sync for Consistent Speeds: Master/slave PWM splitter includes a 4 pin fan connector that transmits the RPM signal to the motherboard, ensuring synchronized fan speeds for both fans. The computer fan splitter omits the RPM signal pin on the second fan for tandem operation.
