Hi! The chip on the MSI KT8 Neo is actually a Winbond w83697hf and is not detected correctly during sensors-detect. I loaded the module with modprobe w83781d force_w83697hf , but this didn't change the PWM problem. pwmconfig can't detect a usable a correlation: Testing pwm control 1-0290/fan1_pwm ... 1-0290/fan1_input ... speed was 3229 now 0 It appears that fan 1-0290/fan1_input is controlled by pwm 1-0290/fan1_pwm Would you like to generate a detailed correlation (y)?
