Synchronizes three PWM fans with your motherboard Bios! Combining the power of a PSU MOLEX connection with the versatility of a PWM motherboard connection for the very first time the Akasa AK-CB002 is a unique product furthering the cause of quiet efficient computing. Supporting three PWM fans from a single motherboard header makes this the ultimate fan splitter for todays low noise performance systems. Case fans and watercooling radiator fans can now benefit from smart and precise PWM control alongside the CPU fan. Utilizing the intelligence of PWM for three fans enables multi fan connection and usage of more powerful fans while allowing their speed to be synchronized with CPU load. RPM feedback for the motherboard is provided from a connector marked CPU fan.
