I'm sorry I meant to say the best VRM of any pre-X570 ITX board. I'll edit my post to correct that.I don't believe that msi board has better vrm's than the current and upcoming x570 itx boards.
I haven't seen any of them reach higher than 52c on the Gigabyte x570 itx.
As far as the chipset fan, I don't hear it and it has reached up to 8k rpm. The bios now supports tuning the chipset fan as well now.
