Hello, I don't know if its a current bios bug, I broke my mobo or its meant to be like that, but my CHA_FAN 1 can't control any 3-pin fans, it can control pwm fans only, but the thing is CHA_FAN2 and CHA_FAN3 can control both 3-pin fans and pwm fans, so i don't know whats the issue

have you read the manual ?
i recall some of my fan headers do not support both fan types

i use the case fan controller anyway on my system as most of them were already wired to that and i havnt needed to change the speeds since building it

Well I mean its weird that CHA FAN 1 can change only pwm speeds and CHA FAN 2&3 can change both 3 pin and pwm
