My home build is a Ryzen 7 processor on a Gygabyte X470 Aorus motherboard. I run Linux Mint 19.2 Mate and it runs very well. My problem is that the fans are noisy and don't need to operate at full speed, but when I boot Linux, they run up. There is a MOBO utility that would take care of the fans but it is overridden at boot. How can I get Mint to leave the fans alone?
