I installed aio cooler per instructions to the detail. It booted up but had no rpm indicated in pump. Actually it said 8642 which is not right anyway. But there are 2 wires that are not talked about in directions. One 4 pin male wire labeled pump. And other 4 pun female wire that looks like it should plug into cpu fan header. . I tried gigabyte support they stuck. Instructions doesnt say anything about plugging in cpu fan header and without one plugged in my pc loads fine and everything seems to work . But wonder what to do with the 2 wires. If I actually uh them into each other everything seems to work. I can control from on fan and pump though I cant tell if pump speed actually changes. Question is does anyone know what the 2 wires are for . Doesnt make sense they would send it to me just to plug in to each other when they could do that inside the pump housing. I have z390 aorus motherboard . And aorus 240mm liquid aio cooler
