Otherwise it will not apply the new pwm value. > fan off > > # grep "" pwm2 > 200 > > fan off > > After all, fan is off and does not spin. I am running burnMMX to > produce some heat... seems fan does not run at all. It's pointless to run stress tests. The fan is not automatically controlled (yet), we're still trying 'manual' mode. Once the fan is up and running again (maybe you have to reboot to put the vt1211 back to default values), can you do the 'grep "" *' so that we know which input the fan is connected to? > > # grep "" * > > > 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:1952 > in0_max:2067 > in0_min:1868 > in1_alarm:0 > in1_input:1952 > 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:2015 > in4_max:2203 > in4_min:1795 > in5_alarm:0 > in5_input:3283 > in5_max:3465 > in5_min:3133 > modalias:vt1211 > name:vt1211 > pwm1:100 > 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:100 > pwm1_auto_point3_temp:255000 > pwm1_auto_point4_pwm:255 > pwm1_auto_point4_temp:255000 > pwm1_enable:0 > pwm1_freq:45000 > pwm2:200 > pwm2_auto_channels_temp:2 > pwm2_auto_point1_pwm:0 > pwm2_auto_point1_temp:0 > pwm2_auto_point2_pwm:255 > pwm2_auto_point2_temp:0 > pwm2_auto_point3_pwm:200 > pwm2_auto_point3_temp:204000 > pwm2_auto_point4_pwm:255 > pwm2_auto_point4_temp:204000 > pwm2_enable:2 > pwm2_freq:45000 > temp1_alarm:0 > temp1_input:116000 > temp1_max:147000 > temp1_max_hyst:142000 > temp2_alarm:0 > temp2_input:57000 > temp2_max:65000 > temp2_max_hyst:60000 > vrm:85 Well it looks like it applied your pwm values. pwm1 and pwm1_auto_point3_pwm match and pwm2 and pwm2_auto_point3_pwm match. The fan is not spinning? What if you bump the values to 255? ...juerg >
