Cool, thanks so much for the help!

I was talking to some people on the /r/buildapc discord last night and I think we figured something out, although I still want to make sure my motherboard isn't going to be fried when I plug everything in. I joined the conversation right after another guy had asked the exact same question I had and I went through and tried to follow everything they had said in the conversation as it seemed to work for him. However, I want to make sure I understand it and I'm not going to fry my motherboard when I try to connect it. I think I need to plug the three fans directly into the mobo, into the individual SYS_FANX headers, where the X is just a number. Then, I need to plug the aRGB leads into this one cord that connects all the aRGB to an RGB controller in the front panel. This cord is labeled "MAIN". Finally, I take the molex connector from the RGB controller and plug that directly into the power supply. This way, I'm not plugging in a 5V aRGB connector to my mobo and instead plugging them all in simultaneously directly to the power supply. The RGB will then be controlled by the case itself instead of software the motherboard uses. Does this sound correct? Below is the diagram that the incredibly helpful people on Discord made for me.

Hello everyone, I'm brand new to building PCs (and brand new to this forum) so go easy on me and forgive me for the basic questions I need help with! The case I bought (Matrexx 55 Add RGB) came with a few fans that each have their own cables. My mobo, an MSI X470 Gaming Plus, has four fan headers. I originally thought these were compatible with one another, but after reading up on it some more, I read something about how these fans are 5V and I'm not sure if my mobo is only 12V. I am so confused by what this even means. I need to know if I can use these fans on the case and, if so, how. Also, I need to know how to plug the RGB in. There is absolutely no instructions in the manual and the instructions in the YouTube video are pretty useless. My motherboard has two headers for CPU power, an 8 pin (CPU_PWR1) and a 4 pin (CPU_PWR2). Do I need to plug the PSU into both of them, or just the CPU_PWR1? I am using a Ryzen 5 2600X with an rx 570 GPU. Thanks in advance for any advice and I'm really sorry for these newbie questions
