Hello, It seems the best would be to disable the fancontrol script it must load from /etc/ you can see it active with ps ax command. Unfortunately I'm not very familiar with fancontrol stuff and I dont know your Linux distribution but here is general steps: Steps for manual control: 1) disable (or delete fancontrol script that loads on startup of computer) 2) go to /sys/bus/i2c/devices/0-290/ (the directory 0-290 might be different, just inspect every directory in devices/ and find that one with "pwm1" ... files) 3) to change fan speed do: echo 128 > pwm1 (or pwm2 etc depends how is your fan connected, values are from 0=stop 255=fullspeed) 4) you can use pwmconfig to tell you the correlation values between fanspeed and PWM value. 5) put the echo ... > /sys/bus/.... line somewhere to startup scripts. I hope this helps. Regards Rudolf
