I'm pretty new to PC building so I could be making an very easy mistake, but in my Coolermaster mastercase h500p mesh It has 2 big fans on the front. They have only one cord on each that connect to a spliter then it brakes off into 2 different cords, one goes into an rgb remote to control the rgb but the other I'm guessing powers the fans but I can't for the life of me figure out where it goes. My motherboard is the Prime z370-A ll and I have checked the manuel and can't seem to find where it goes. I can add photos and answer any questions if need. Any help would be greatly appreciated.
