Okay, so, after trying a new NVMe with a fresh install of Windows, I tried only iCue and everything works but I can't control the motherboard RGB, obviously. I uninstalled iCue, installed RGB Fusion, I can control the motherboard RGB just fine and even the Corsair RAM now without issues.
So the issue ends up being RGB Fusion and iCue installed at the same time ends up corrupting something with Windows when both are present. Because everything is working on this fresh install but when I went back to my main install of Windows, problems persisted.
HOWEVER!, this afternoon, my 1080ti got delivered, so I shut everything down, tossed that in.
And it was a TIGHT FIT so I'm kind of glad taking those 140 fans off the h115i fixed the RGB momentarily yesterday.
I had to install yet another RGB program to control the RGB in the new GPU, and now, suddenly iCue just decided to start working again normally, no issues with RGB fusion, and now this new third program by EVGA, but everything is actually working perfectly. I have no idea what's going on, but a combination of removing the fans from the h115i and installing the EVGA software fixed my issues and now everything is working again.
So, Conclusion, if anyone else is having this issue, it's RGB Fusion and iCue conflicting and it breaks your install of Windows, you need to do a fresh install of Windows to correct the issue, only use one of the two programs, or happen to luck out by installing the EVGA software on top of already having RGB Fusion and iCue installed, and then everything just glitches itself backout into a working state.
Now an actual fix for this issue that I've been trying to figure out, is Thermaltake AIO coolers, they're compatible with RGB Fusion, and you can apparently repin the Corsair fans to be compatible, it's only the Corsair PLUGS that don't work with Gigabyte, I found a few things on reddit and some videos on youtube about this where someone just replaced the Corsair RGB connectors with standard fan header connectors, MSI has a document for what wires are which signal because some MSI stuff has the proprietary Corsair RGB header on the motherboard.
So the ACTUAL FIXES, I have three methods, none of them are great.
Fix 1) Replace everything Corsair with an RGB Fusion certified brand, Thermaltake AIO Coolers seem to be the best bag for buck from what I found and they actually perform better than the Corsair stuff from some benchmark videos I saw, so, might be worth looking into for a small performance gain in thermals.
Fix 2) Rewire all of the Corsair Fans to be compatible with the standard RGB headers most manufacturers use, as for the AIO pump, cover it in tape, it'll always flash RGB without iCue installed.
Fix 3) This seems to be the best solution for most, it's a hassle, but, the most effective and doesn't cost anything. From what I found thought my testing is that RGB Fusion saves the settings in BIOS, so even with the program uninstalled, it still activates the motherboard RGB to white while it's on, and when it's off it has a breathing effect with purple RGB, turns out the EVGA software ALSO does the same thing by saving the RGB settings either to the system BIOS or the GPU BIOS, either way, all you need to do, is install say RGB Fusion, set all your motherboard settings to how you want it, save, reboot to make sure they stay in effect, once back at the desktop, uninstall RGB Fusion, go on to the EVGA software, repeat, once RGB Fusion and EVGA are set and uninstalled, install iCue, and leave that installed as it only activates your profiles once in Windows.
This way you can set the motherboard, set the GPU, and still have Corsairs proprietary software that refuses to play nice with others.
But anyway, thanks for the help, got it all figured out, but to end this on a bold note, I bought a NZXT H510 Elite and looking at two Thermaltake AIO coolers lol, I'm getting rid of everything Corsair so I only need to run RGB Fusion, and with the NZXT Kraken G12, I won't need the EVGA software becuase I'll be replacing the entire cooler with one of the two Thermaltake AIO's I ordered.
So if anyone wants a Corsair Spec-OMEGA RGB, a bunch of 120 HD fans, and an H115i, they'll be on ebay as soon as the new stuff arrives haha
