Well designed X570 chipset coolers can run nearly always passively, if you just have ambient temperature under control. (=working case cooling)
So especially Asus has badly retarded HSF designs from arse of brand overhype marketroids.
Gigabyte and MSI did lot better job in using common sense during design.
Though bang per buck X570 Aorus Elite has the most sensible cooler of Gigabytes with higher model design showing more interference from marketroids.
Again while having widely the best chipset HSF, MSI tried riding on brand reputation from B450 boards and except for Tomahawk have crap CPU VRM copypasted from £100 B450 boards in whole lower half of the X570 range.
I bought the MSI x570 MAG WiFi Tomahawk today.
I was starting to worry that I missed something but i just saw the price of it. If you have good airflow these fans don't seem to turn on at all apart from booting.The Asus X570 Crosshair Dark Hero has no chipset fan, it was one of the main reasons why I purchased it.
