Dear tsaybird,

Greetings, this is ASRock TSD.

For AB350 Pro4, there are three chassis fan connector, CHA_FAN1, CHA_FAN2 and CHA_FAN3.

CHA_FAN2 and CHA_FAN3 could control both 3-pin and 4-pin fan, but CHA_FAN1 could only control 4-pin fan.

Regarding your question, please install a 4-pin fan on CHA_FAN1 to customize the fan setting.

If connecting 3-pin fan, it will work at full speed.

Here is the specification for your reference as below.
