Now can you please run cpuid and 'grep "" /sys/class/hwmon/hwmon*/device/temp?_input' in close succession a couple of times (maybe 5 times with a couple of secs in between) while the system is idle and then again while the system is busy (by running cpuburn for example)? This should allow me to calculate the correct values for the conversion that goes into sensors.conf. >> 3) What is the rev of your vt1211?

Write 1 to pwmX_enable (where X is the >> number of the pwm controller that controls the CPU fan). And then try writing different >> values in the range 0-255 to pwmX.

Manual mode was never implemented as it doesn't seem to work. > Ive just verified that pwm1_enable and pwm2_enable controls the same fan, fan2 in my case (cpu fan). > > echo 2 > pwm2_enable and echo 1 > pwm1_enable turn that fan off. Either of this command enables the fan auto controller in the vt1211. As I mentioned earlier, there is only a single controller that affects both PWM outputs. ...juerg
