I just purchased the x570 Ultra with the Corsair H100i cooler to go in a Phatenks Ethnoo Pro case. The newbie question I have is to confirm which header to Plug the cooler into. The case comes with a PWM controler which asked to plug the main line into the CPU_Fan header. If that goes there should I plug the H100i into the CPU_Opt or does that go to the PWM hub (Fan 1)? I just wanted to be sure. Thanks.
