All panels suffer from backlight bleeding, and being a certain type of panel doesn't make it inherently better or worse. It's just down to the manufacturing techniques and it can still be an issue on any panel.
Wanting to upgrade my monitor. Never had an ultrawide and I'm torn on these two. Any advice or suggestions? I know the LG one has HDR but the MSI one doesn't. I'm leaning more to the LG

Probably something to do with the install. Intel to Intel is fine, but AMD to Intel isn't. There's more of a process to go through since its different chipsets and drivers.
If the BIOS ships with a particular version then it might need an update before you can use the CPU.
EDIT:
Checked PCpartpicker with the 7950X3D and it seems like its good to go.
Any high temps will damage anything, but as long as there is adequate air flow going to the GPU, it should be fine. Also, if that happens, normally the GPU will throttle itself in performance to save it from climbing any higher in temp.
Is there even contact between said cooler and the CPU? Are you for sure the pump isn't dying? If its still working, then try reseating CPU. Does that mobo have a dedicated AIO header and is the pump plugged into it?
