Hi all

I just want to ask or find out about fan optimization in the Asus Bios settings. I have the PRIME B450 PLUS. I have chassis fans and my cpu fan. My current fan profiles are all standard. They are all on DC Mode except the cpu is PWM as wall as all turned on to motherboard. What does the optimisation button do in the W control. I clicked it and now it says

Cpu fan min duty cycle(%)40>40
Chassis fan 1 min.duty cycle (%)60>31
Chassis fan 2 min duty cycle(%)42>42
Chassis fan 3 min duty cycle (%)60>31

Is that bad or must I change them all back to standard?it says fan source cpu or motherboard which option to I choose they are all on cpu. Fan 1-3 are all on 200rpm speed low limit is that correct as I haven’t touched it
