I hope I can get a pretty quick response to this inquiry as I am building this PC right now. I have a computer that was given to me and I am upgrading/rebuilding and I have a small problem. I have attached a diagram of my situation I need to know which wire(s) go to controller motherboard and so forth. The fan I am using is missing, as shown, one of the plug ends but I can solder on on as required.
