I installed armoury crate service from the laptops page, and then the UI on the windows store which allows to switch from silent/normal/turbo mode. This alone and switching out of silent mode was enough to make it behave.
I don't know, as suggested on this article it stays on silent mode on Linux, and a new version will bring the ability to switch modes: https://www.phoronix.com/scan.php?page=news_item&px=ASUS-TUF-Ryzen-Thermal-Fix
Or maybe like you say, it can switch modes, but it does it in a not very smart way...
