Well, "i" am sorry, i read the document about lm85 chip and i may not have enough technical knowledges to understand how to give the right parameters in /etc/sensors.conf This is the intersting part of this file (in the lm85 and co section) : set pwm1_zone 123 set pwm1_min_ctl 0 set pwm1_min 0 set temp1_min 20 set temp1_max 60 # dothan's max temp is actually around 100?C set temp2_min 10 set temp2_max 45 set temp3_min 10 set temp3_max 45 If i run "sensord -i 1m -l 30m", i read this in /var/log/syslog : Error getting sensor data: adt7463/fan1_tach_mode: Can't access procfs/sysfs file I get the same message in /var/log/syslog if put this line in /etc/sensors.conf: set fan1_tach_mode 0 I can't understand that... Actually this may be the reason why the fan doesn't seem to follow the policy i give him in /etc/sensors.conf, as i told before. > >In spite of my settings the fan1_pwm is always at a minimum of 127, which > >means a little more than 3000 rpm.

OK so here is what i get if i run "head /sys/bus/i2c/devices/0-002e" : ==> alarms <== 394 ==> detach_state <== 0 ==> fan1_input <== 0 ==> fan1_min <== 500 ==> fan1_pwm <== 0 ==> fan1_pwm_enable <== 1 ==> fan2_input <== 0 ==> fan2_min <== 0 ==> fan2_pwm <== 255 ==> fan2_pwm_enable <== 1 ==> fan3_input <== 0 ==> fan3_min <== 0 ==> fan3_pwm <== 255 ==> fan3_pwm_enable <== 1 ==> fan4_input <== 0 ==> fan4_min <== 0 ==> in0_input <== 0 ==> in0_max <== 1576 ==> in0_min <== 1419 ==> in0_ref <== 1850 ==> in1_input <== 1207 ==> in1_max <== 1945 ==> in1_min <== 1758 ==> in2_input <== 3369 ==> in2_max <== 3472 ==> in2_min <== 3128 ==> in3_input <== 3281 ==> in3_max <== 5260 ==> in3_min <== 4740 ==> in4_input <== 0 ==> in4_max <== 12625 ==> in4_min <== 11375 ==> name <== adt7463 ==> power <== head: Erreur lors de la lecture `power': Is a directory ==> temp1_input <== 54000 ==> temp1_max <== 60000 ==> temp1_min <== 30000 ==> temp2_input <== 48000 ==> temp2_max <== 50000 ==> temp2_min <== 20000 ==> temp3_input <== 48000 ==> temp3_max <== 50000 ==> temp3_min <== 20000 ==> vrm <== 91 I thought that the the chip itself could handle fan speed according to temperatures. Shall i use fancontrol instead ?
