4Pin 1 to 3 Ways PWM Fan Splitter Cable Sleeved Fan Power Exion Cable 4Pin Female to 3X 4Pin Male,3 Way 4 Pin PWM Fan Splitter Cable 12 Inches, PC Fan Splitter 1 to 3 Converter, PC Fan Extension Cable

4 pin fan splitter cable connects 3 computer case fans to a single motherboard fan header. PWM splitter cable connects an additional fan to increase airflow in your computer case. Fan speed label on the 4 pin fan master connector of the fan header splitter is wired to receive the PWM control signal and share it to the slave fans. PC fan splitter connects to the 4-Pin header on the motherboard and splits the signal to 3 PWM fans. PWM fans can spin at the same speed using software from a motherboard equipped with PWM control.

CPU fan splitter has a 4 pin fan connector a wire that sends the RPM signal to the motherboard connector for synchronizing the fan speed with the other 2 fans. 3 pin fan connector omits the RPM signal pin for tandem fan speeds with all 3 fans when supported by your computer and fans. Can be used for a motherboard 4pin interface powering for multiple cooling fans and PWM speed control, lengthen and extend the motherboard 4-pin interface.
