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. Besides, please also refer to the following link for the fan type specification and information. Thanks! All the best, ASRock TSD |
