Hello, the AIO (Corsair H100i platinum SE) I'm installing has a 3 pin fan connector that I'm supposed to plug into the cpu_fan header but the motherboard I'm using (Z390 Aorus pro wifi) has a 4 pin header. I know that I can plug it into a 4 pin header but I don't know if I'm supposed to plug it into the first three pins on the left or the three last pins to the right... Thanks in advance.
