The new crop of X570 boards, labeled X570S or something, do not have a chipset fan. (Also on the original ones, the fans might've had full silent modes where they only spin up when pushing big PCIe bandwidth over the chipset?)

There’s a few like the X570 Dark Hero which also don’t have a chipset fan but don’t use the X570S label.
