Well this is just to try to figure out if you can actually control the fan. Currently pwm2 is set to 255 so the fan should be running at full speed. You can try 0 and see if the fan stops. But be careful, if the fan is actually cooling something that something could overheat and die if you disable the fan! > # cat pwm2_auto_point3_temp > 0 Chip default. > > echo -99999 > pwm1_auto_point3_temp > > echo 999999 > pwm1_auto_point3_temp > > > > And you can check the current pwm value: > > grep "" pwm2 > > grep "" pwm2 > 255 > > > If your fan is controlled by pwm1, change pwm2 to pwm1 in the above > > commands. > > > > After you issued the above commands, can you post the output of > > 'grep "" *'? > > Let me know how it goes. > > alarms:4608 > cpu0_vid:1250 > fan1_alarm:0 > fan1_div:2 > fan1_input:0 > fan1_min:3006 > fan2_alarm:0 > fan2_div:2 > fan2_input:0 > fan2_min:3006 > in0_alarm:0 > in0_input:1962 > in0_max:2067 > in0_min:1868 > in1_alarm:0 > in1_input:1973 > in1_max:2119 > in1_min:1910 > in2_alarm:0 > in2_input:1221 > in2_max:1253 > in2_min:1180 > in3_alarm:0 > in3_input:1942 > in3_max:2119 > in3_min:1733 > in4_alarm:0 > in4_input:2004 > in4_max:2203 > in4_min:1795 > in5_alarm:0 > in5_input:3283 > in5_max:3465 > in5_min:3133 > modalias:vt1211 > name:vt1211 > pwm1:255 > pwm1_auto_channels_temp:1 > pwm1_auto_point1_pwm:0 > pwm1_auto_point1_temp:0 > pwm1_auto_point2_pwm:255 > pwm1_auto_point2_temp:0 > pwm1_auto_point3_pwm:255 > pwm1_auto_point3_temp:0 > pwm1_auto_point4_pwm:255 > pwm1_auto_point4_temp:0 > pwm1_enable:0 > pwm1_freq:45000 > pwm2:255 > pwm2_auto_channels_temp:1 > pwm2_auto_point1_pwm:0 > pwm2_auto_point1_temp:0 > pwm2_auto_point2_pwm:255 > pwm2_auto_point2_temp:0 > pwm2_auto_point3_pwm:255 > pwm2_auto_point3_temp:0 > pwm2_auto_point4_pwm:255 > pwm2_auto_point4_temp:0 > pwm2_enable:0 > pwm2_freq:45000 > temp1_alarm:0 > temp1_input:111000 > temp1_max:147000 > temp1_max_hyst:142000 > temp2_alarm:0 > temp2_input:63000 > temp2_max:65000 > temp2_max_hyst:60000 > vrm:85 > > Will I have to perform the following steps on each reboot? Yes. But if you really plan on using a fan and if it can be controlled by the vt1211 I recommend using the automatic mode. Then the vt1211 is picking the pwm value based on the measured temp and you don't have to deal with it. You still need to set the chip up after every reboot. But let's try manual control first and if that works, we'll go from there. ...juerg > Regards, > > c. > > > >
