Okay my build will be the MSI Z97 Gaming 5 mobo that has two CPU headers and three case headers, Corsair H100i and My case is the Corsair Air 540.The H100i will take up one 3 pin header and My case comes with three case fans.So with the H100i are any of My CPU headers taken up or would I have a free one to plug in my third case fan or are there any better solutions to use my case fans?
