i have an asus z170 pro gaming motherboard and a nzxt n450 case. there are 3 front panel fans and 1 rear fan. I have already used the cpu_fan header for my cpu fan. From what i've heard, I'm suppose to connect my case fans to cha_fan. But I don't know excatly how. what do the fan cables look (the one that i need to plug into CHA_FAN) like. Do I plug all the 4 fans into one cha_fan? where do i connect my power button cable? where do I connect my LEDS?
