[SOLVED]pwmconfig fails to find fan sensor on Intel D510MO motherboard

Question

Hello there,
i can't find any info about this motherboard on wiki and google on this problem.
i've installed lm_sensors and got this running sensors:
coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +19.0°C  (crit = +100.0°C)                 
coretemp-isa-0002
Adapter: ISA adapter
Core 1:      +15.0°C  (crit = +100.0°C)                 
w83627thf-isa-0290
Adapter: ISA adapter
in0:         +1.17 V  (min =  +0.00 V, max =  +3.84 V)   
in1:         +1.01 V  (min =  +2.05 V, max =  +0.00 V)   ALARM
in2:         +1.90 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
in3:         +3.02 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
in4:         +3.41 V  (min =  +0.02 V, max =  +0.00 V)   ALARM
in7:         +2.99 V  (min =  +0.27 V, max =  +0.13 V)   ALARM
in8:         +3.23 V  (min =  +0.00 V, max =  +0.00 V)   ALARM
fan1:          0 RPM  (min = 1318 RPM, div = 32)  ALARM
fan2:          0 RPM  (min =   -1 RPM, div = 32)  ALARM
fan3:          0 RPM  (min =   -1 RPM, div = 2)  ALARM
temp1:       +48.0°C  (high =  +0.0°C, hyst =  +0.0°C)  ALARM  sensor = thermistor
temp2:       +29.0°C  (high = +80.0°C, hyst = +75.0°C)  sensor = diode
temp3:       +29.0°C  (high = +80.0°C, hyst = +75.0°C)  sensor = diode
beep_enable:enabled
i've tried run pwmconfig and got this:
Found the following devices:
   hwmon0/device is coretemp
   hwmon1/device is coretemp
   hwmon2/device is w83627thf
Found the following PWM controls:
   hwmon2/device/pwm1
   hwmon2/device/pwm2
   hwmon2/device/pwm3
Giving the fans some time to reach full speed...
Found the following fan sensors:
   hwmon2/device/fan1_input     current speed: 0 ... skipping!
   hwmon2/device/fan2_input     current speed: 0 ... skipping!
   hwmon2/device/fan3_input     current speed: 0 ... skipping!
There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
See doc/fan-divisors for more information.
anyway i managed to control my system fan to monitor temp1 (motherboard temp) running:
echo "180" > /sys/class/hwmon/hwmon2/device/pwm1
but i need to run it as root and pass "yes" to pwmconfig first to activate manual control
so i need a bash script to run this  automatically on startup,i found this one and modified it but i need help to get pwmconfig run with "yes" before start my if...else control to launch "echo..." once temp1 reach 50 C°
this is original:
#!/bin/sh
### Temperature guard
### Auto Shutdown if Temperature is over threshold
THRESHOLD=57 # Max temperature
SENSORS=/usr/bin/sensors
PATH=/bin:/usr/bin:/sbin:/usr/sbin
test -x $SENSORS || exit 0
echo "Temperature Guard started. Threshold temperature is $THRESHOLD °C"
logger "Temperature Guard started. Threshold temperature is $THRESHOLD °C "
while [ 1 ]
do
## Get Temperature using lm-sensors
t1=`$SENSORS | nawk '/temp1/ {print substr($2,2,2)}'`
t2=`$SENSORS | nawk '/temp2/ {print substr($2,2,2)}'`
t3=`$SENSORS | nawk '/temp3/ {print substr($2,2,2)}'`
# log every 15 minutes

if [ $t1 -gt $THRESHOLD -o $t2 -gt $THRESHOLD -o $t3 -gt $THRESHOLD ]
then

logger "Temperature Guard: PANIC!. CASE: $t1°C CPU: $t2°C BOARD: $t3°C Shutting down immediately!"
shutdown -h now # requires %user ALL=NOPASSWD: /sbin/shutdown in visudo
else
echo -n "\rTemperature Guard: OK. CASE: $t1°C CPU: $t2°C BOARD: $t3°C"
fi
sleep 5
done
done
any good person here to help me? :)

Answer 1

solved
1)
install with pacman:
lm_sensors
yaourt
sudo
nawk
refer to the wiki of archlinux to install and configure this packages
2)
save this script and  add it to startup and shutdown of kde settings (i assume you are using kde,and i suggest you to install it)
(example sudo path/to/yourscript.sh)
#!/bin/sh
### controllo ventolina
### controlla in automatico la velocita' della ventolina data la temperatura
SENSORS=/usr/bin/sensors
PATH=/bin:/usr/bin:/sbin:/usr/sbin
test -x $SENSORS || exit 0
sudo sh -c "echo 1 > /sys/class/hwmon/hwmon2/device/pwm1_enable"
while [ 1 ]
do
## prende la temperatura da lm-sensors
t1=`$SENSORS | nawk '/temp1/ {print substr($2,2,2)}'`
if [ $t1 -gt "49" ];
then
echo "180" > /sys/class/hwmon/hwmon2/device/pwm1
echo "temperatura $t1 gradi \n" ##comment this lines if you don't want to run in console
sleep 20
elif [ $t1 -gt "47" ];
then
echo "170" > /sys/class/hwmon/hwmon2/device/pwm1
sleep 20
echo "temperatura $t1 gradi \n"
elif [ $t1 -gt "45" ];
then
echo "157" > /sys/class/hwmon/hwmon2/device/pwm1
sleep 20
echo "temperatura $t1 gradi \n"
fi
done
