Hello, I have 2 corsair rgb led fans with The HD lighting controller and fan hub. I use these fans as intakes on the front of my case. They have 4 pin headers. The rgb customiser is working fine. However I cannot control the fan speeds. One fan cable each is connected to the hub, and the others are plugged into sys_fan headers on the motherboard. The hub is connected to the power supply, and to the lighting controller. I think that connecting the fans to the cpu_fan header will fix this, but I only have 1 available cpu_fan header left, and I need to connect 2 or 3 fans. My other cpu_fan header is being used by the cpu cooler (h100iv2). Any help please? Thank you. I also use corsair link software.
