I cannot confirm this. I use the same board, i7 12700KF, Corsair Vengeance RGB RS 2x32GB with a Gainward RTX3050 Ghost.
So far no problems at all, and I also play CoD WWII, Rust etc. on it. Maybe the HDD is spiking? I have two SSDs installed...
The board itself does not support RGB control - so it supplies power for the fans. But controlling the colours is not.
MSI marks the motherboards with integrated RGB control on their website with a corresponding icon on the preview images: https://us.msi.com/Motherboards
It actually has exactly the same number of fan headers as the one you asked about yesterday (;
- 1 4-pin CPU fan header
- 1 4-pin pump header
- 5 4-pin system fan headers
