Hello,
since recently i own an ASRock B450m Pro4-F motherboard. It has everything i need on a MB, but the fan on CHA_FAN2 is always running on maximum speed. In the BIOS there is only the possibility to control CPU_FAN and CHA_FAN1. Can somebody please give me an advice how to control CHA_FAN2. I have already tried SpeedFan.

Hi

Only 4 pin fan headers can be controlled via BIOS, seems that your B450M Pro4-F has 1x4-pin for CPU and 1x4-pin for chassis, that's why no options in BIOS to control CHA_FAN2, because it's 1x3-pin fan header.

I would recommend you a 4-pin fan splitter and forget CHA_FAN2, you'll be able to control all chassis fans.

Best regards and good luck
