[SOLVED] Lm sensors and Toshiba 4090XCDT

Hi there,

I try to setup lm_sensors on a pretty old rig (Toshiba 4090XCDT) I own to no avail. I followed http://wiki.archlinux.org/index.php/Lm_sensors but all I get is (...)

[orange@arch ~]$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +20.0°C  (crit = +95.0°C)                  

adm1021-i2c-0-4e
Adapter: SMBus PIIX4 adapter at fe70
temp1:       +48.0°C  (low  = -55.0°C, high = +127.0°C)  
temp2:       +65.0°C  (low  = -65.0°C, high = +70.0°C)

My goal is to control the speed of the CPU fan that spins all the time at full speed following http://wiki.archlinux.org/index.php/Fan_speed_control
Does anyone have experiences with that particular laptop? Any suggestions I may try to get this running?

Thanks!

I solved this problem in the meantime by writing my own fan control script. Not sure if it might be useful for someone else, but I thought sharing it (at least) cannot harm (...)

[orange@arch ~]$ cat /usr/local/bin/fancontrol 
#!/bin/sh
if [ "$(sensors | tail -n 3 | awk '/temp1/ {split($2, a, "."); split(a[1], b, "+"); print b[2]}')" -lt 65 ] && [ "$(awk '/running/ {print $2}' /proc/acpi/toshiba/fan)" -eq 1 ]; then
    echo "force_on:1" > /proc/acpi/toshiba/fan
    echo "force_on:0" > /proc/acpi/toshiba/fan
fi
if [ "$(sensors | tail -n 3 | awk '/temp1/ {split($2, a, "."); split(a[1], b, "+"); print b[2]}')" -gt 70 ] && [ "$(awk '/running/ {print $2}' /proc/acpi/toshiba/fan)" -eq 0 ]; then
    echo "force_on:1" > /proc/acpi/toshiba/fan
fi

This fan control script gets executed every 30 seconds as cronjob.
