The FrozenCPU PMW Y Splitter Cable allows one PWM port to control two PWM fans. Only one of the 4-pin connectors reports the fan speed back to the fan controller so as to not confuse it. PWM offers better control than traditional fan power systems and is usually found on the latest motherboards for CPU fan power and more.
Note: This product comes sleeved black by the factory. Use the sleeving options below only if you want us to change the sleeving to a different color.
Warning: Please check how much power your motherboard's fan header can supply before connecting two fans to it. If the combined fans draw more power than the motherboard is rated to supply, they may damage the motherboard.
