    case fan connectors

    ASROCK Extreme 4 mobo i7-3770K 16 GB RAM
    My final build and almost done.

    The case has a 120mm fan that has both a 4-Pin molex connector and a 3-Pin chassis fan connector

    I'm thinking I only need to plug one in. The 4-pin connector will be continuous fan or the 3-pin connector will be intermittent fan controlled by mobo.

    Is that right or would the 3-pin connector just be a thermostat if I plug them both in?

    If the fan has a 4 pin Molex and a 3 pin plug then the molex plugs into a power supply plug and the 3 pin plug feeds rotation info to the motherboard. You may need to replace the fan with a 4 pin connector like this
