In my ASUS-PRIME Z590-A motherboard I trying to use Q-Fan to control my chassis fans.When I enter to the Q-Fan control screen in the BIOS, I see the Stop Fan checkbox, but it is disabled.
The fan is working, and the BIOS seems to be detect it and its RPM. The fan has 3 pin connector, which is connected to the mobo' 4 pin connector.
Question
How can I activate this possibility?
