(I was thinking to solve the issue that way- RGBFusion not working - same) Now the only thing that appear in RGBFusion2.0. RGB fusion worked fine till some months ago, finding : I'm on a Z390 Aorus pro WiFi Bios 9A (for good reason ) I had created a custom profile previously, for blue lighting, and I went ahead and deleted the profiles stored inside the RGB Fusion 2.0 software. Have fiddled around with the software, double checked all my connections, and still only blue. And then after powering down and turning PC back on later, I've only got blue LED. Issue is that the software was controlling everything perfectly. I could change all the colors flawlessly, however being on a 1 to 4 splitter each LED had to be the same color. Now, this setup was working flawlessly for a time. I have the arrow imprinted on each 4 pin matched up correctly, and the arrow matched up on the mobo to the side indicating 12V.

The three fans each have a 4 pin RGB header, and a single connection for power off the power supply. The case came with all three fans preinstalled. I have a 1 to 4 splitter connected to an AMD Wraith Spire cooler (2700X CPU) and the other three going to my fans in a Cooler Master case. First off, I'm running a Gigabyte Aorus B450M motherboard with one LED header, it's got a 12 volt pin. I will attempt to provide as much info as possible. Having trouble with the Gigabyte RGB Fusion 2.0 software, I think.
