Are you really expecting Asus to answer you or make a comment about this for their future X570 boards?
If you're expecting an answer you're wasting time, especially on a user-to-user forum.
You could try opening a support ticket and asking there. But even so, don't expect any answer as clear as your question.
It's not an issue acknnoledged by Asus. Myself for example, I have a Corsair H115i PRO RGB operating on the CH7 without issues.
So the only thing you can do is wait and see if people with the X570 boards are still experiencing the issues you deal with, or buy it and risk, or get the MSI straight away.
