I have a Jetway K8M8MS motherboard with a Fintek F71805F chip, where pwm1 controls fan1. So I am reasonably certain that fan speed control is properly implemented by my f71805f driver. However, you are not the first one to report about being enable to control the fans using this driver. It seems to be common that motherboard manufacturers don't bother wiring things properly :( -- Jean Delvare
