I've done what you suggested and still no results. So I made a video explaining what is happening. I will send a private link of the video which it can only be watched here. Take not of the fan on the top right attached on the pc exhuast that it is working perfectly on CPU_OPT header. First Link: https://www.youtube.com/watch?v=gsIAfxjC2W0 This video explains the issue when turning the computer on and the lights just blink and disappears but the fan is still turning, then I go to the BIOS and configure the fans to max speed and PWM mode. with no affect. Second Link: https://www.youtube.com/watch?v=4XlBrd2zldI This video is what I've discovered is when you unplug the fans while the computer is on and plug back again, the fans work properly. The second video gives me another question, could it be that there is a power spike/loss during booting that would create an unstable connection to the rgb control? if so how do we address this issue? I also sent this to gigabyte to give their opinion on this issue.

My first time with this forum as a result of my frustration with this issue I connected riing fans through RGB/speed controllers though the CPU_OPT and sys_fan2 headers, which is the most efficient for cable management. However, another set for riing fans I installed it on my top mounted radiator and I connected the RGB/speed controller to sys_fan3 the fan is spinning but the RGB lights are turning off whenever I boot, which does not happen to the other fans. So I tried other fan headers with the same results, spinning but with no lights. I tried swapping controllers, and came to the conclusion specific fan headers specifically sys_fan2/3/4 and sys_fan_pump5/6 can spin the fan but cannot power the LED. Is there a setting in the BIOS to fix this. The motherboard is a Gigabyte Z270x gaming 7, I've attached where I determined which headers work (indicated in green) and do not work (red), the one indicated in Blue are the ports the controllers are connected. I also sent a copy of this photo to Gigabyte and contacted TT support, still waiting for their replies.
