  1. Hey guys. On my raid, I have two 120mm fans that are four pin females. I want to control them on my cooler-masters fan controller. In order to do this, I will need to convert the pins to three pin.

    The most cost efficient way is to have the splitter first then the converter. Two cables instead of Three.

    The problem I am having is that I cannot for the life of me find a male four pin to a three pin female connector.

    Amazon and Ebay has failed me. (only offers 4 pin molex to three pin. Not what I need.)

    Where do I find one of these cables?

    If you are connecting them to a fan controller the fourth pin does not matter so much.

    Its a PWM pin that allows your motherboard to control the speed of the fan. Since you will not be using the motherboard headers you will not need it. You can just offset the connector in the socket.

    What model is your fan controller?
