Cable extension Fan connector: 4-pin Black The Kolink 1-4 PWM Fan Splitter Cable is a 1-to-4 PWM fan splitter, which allows the user to connect up to four PWM fans from just one PWM fan header on the motherboard. Because the fans are PWM controlled the RPM of each fan will change depending on the temperature of the CPU and/or motherboard BIOS settings, meaning the RPM and therefore noise will be reduced if the system does not demand high airflow. The extra power required to run four fans from this splitter is provided by the SATA male connector, which does need to be connected if more than one fan is used.
