I am so thankful to find this thread though I am sad to see there is no resolution. My boyfriend and I have been working on building him a kicking gaming rig and this was HIS choice of case. We are using the ASUS tuf gaming plus WiFi x570 (great name huh, so creative). We have this paired with a ryzen 5 3600x. I have tried swapping the location of all the fans and still only the one in slot one works, currently set to top front fan. As a experiment I left the first fan unplugged and none of the LEDs worked, not even with the built in controller. I will be contacting ASUS next just to try and solve this from both ends. Hopefully a resolution will be found soon.
