I have installed the latest BIOS 7.20 for the AsRock AB350 Pro4 today. The whole procedure was successful, but for some reason now I can't control cassis fans using BIOS options. As result, both preset profiles and user settings are ignored by the motherboard. This definitely applyes to CHA_FAN_1 and CHA_FAN_2.

Please help me to solve this problem.

It is definitely a BIOS bug.

The described problem has been solved in the new 7.40 UEFI firmware.
