Corsair Obsidian is said to be pretty good, had to use a Cooler Master myself due to limited availability of full tower chassis in stock back then but I’ve heard good things about them.
EDIT: Though I don’t think “All” is a good answer for how many fans and for optimal airflow and circulation but it’s probably not the stock setup either.
EDIT: Also it’d be nice to see a return to the age of copper for some of these designs speaking of cooling and thermals.
Higher-end motherboards are already 300 - 500 US Dollars if not more sticking a dinky tiny plastic fan and some tiny metal heat spreader on the chipset and such you’d think they could do better.
Think you need the 600 - 900 US Dollar boards for AMD’s X500 motherboards to get silent cooling because double the price for a few extras and leading some heat pipes around the chipset is definitively a 2x price bump.
Eh would probably be even more if the designs ever returned to the Intel 30 and 40 series days of bolting that much copper on plus the happy bright colorful all the colors paint job.
