Is there a way through bios to change the way the mobo controls the fans (instead of PWM to switch to classic 3pin control process?)

Otherwise the only way is a fan controller or maybe adapters 4pinPWM to 3pin?
All headers EXCEPT CPU Fan can use 3 pin and still use Q-Fan.
Use headers marked "Chasis Fan" - 3 headers connect to cpu temp. Use 'silent' profile.
Opt Fan 1-3 are tied to their own temp probes.
PWR Fan is duty mode only.
