[Quan, Evan] No, not such complicated. There are only two fan control mode: auto and manual.
The settings working under manual mode: temp/pwm curve settings
The settings working under auto mode: all others (acoustic limit/target, temperature target, minimum pwm...)
And those settings for auto mode can co-work with each other. They affect the auto fan control via different manners and are not mutually exclusive.

[Quan, Evan] For the sequence above:
1. set a custom temp/pwm curve
- this will switch the fan control to manual mode in order to make the settings to take effect
- this will invalid all other settings working under auto mode only
2. acoustic targets
- this will switch the fan control to auto mode in order to make the setting to take effect
- this will invalid the temp/pwm curve settings working under manual mode only
