ok so I can go ahead and power the case fans? The thing I was most unsure about all along was connecting fans by molex and how they connected to the mobo. There's three places on my mobo for fans, all the molex have 4 pins and 2 of the three places on my mobo only offer 3 pins. To make matters worse, the mobo install manual said that the ground wire would be black but that's impossible by looking at the cable. If this is a non issue and I'm a dumb, I'll be a happy dumb. Otherwise, wondering if I have my case fans wired wrong.
