How to control fan speed (lm-sensors)

Install and config lm-sensors first, see section above. Then run pwmconfig
to test your fans

pwmconfig

If you can control fan speeds, great. Now creat a file called
/etc/init.d/fancontrol, and paste in the following

#!/bin/sh
#
# Fancontrol start script.
#

set -e

# Defaults
DAEMON=/usr/sbin/fancontrol
PIDFILE=/var/run/fancontrol-pid
PATH=/sbin:/bin:/usr/sbin:/usr/bin

test -f $DAEMON || exit 0

. /lib/lsb/init-functions


case "$1" in
       start)
               log_begin_msg "Starting fancontrol daemon..."
               start-stop-daemon --start -o -q -m -b -p $PIDFILE -x $DAEMON
               log_end_msg $?
               ;;
       stop)
               log_begin_msg "Stopping fancontrol daemon..."
               start-stop-daemon --stop -o -q -p $PIDFILE
               log_end_msg $?
               ;;
       force-reload|restart)
               sh $0 stop
               sh $0 start
               ;;
       *)
               log_success_msg "Usage: /etc/init.d/fancontrol
{start|stop|restart|force-reload}"
               log_success_msg "  start - starts system-wide fancontrol service"
               log_success_msg "  stop  - stops system-wide fancontrol service"
               log_success_msg "  restart, force-reload - starts a new
system-wide fancontrol service"
               exit 1
               ;;
esac

exit 0

Make it excutable

sudo chmod +x /etc/init.d/fancontrol

Test it

/etc/init.d/fancontrol start

and

/etc/init.d/fancontrol stop

If it works fine, autoload it when you reboot. Insert the following line
into /etc/rc.local, before "exit 0"

/etc/init.d/fancontrol start

How to monitor CPU, GPU temperatures, fan speeds and voltages (GKrellM)

   - Read #General
Notes<http://ubuntuguide.org/wiki/Ubuntu:Feisty#General_Notes>
   - Read #How to add extra
repositories<http://ubuntuguide.org/wiki/Ubuntu:Feisty#How_to_add_extra_repositories>


   - Install lm-sensors first to monitor CPU temps, fan speed, and
   voltages in GKrellM. #How to detect CPU temperature, fan speeds and
   voltages (lm-sensors)<http://ubuntuguide.org/wiki/Ubuntu:Feisty#How_to_detect_CPU_temperature.2C_fan_speeds_and_voltages_.28lm-sensors.29>


   - Install nvidia video driver to monitor the nvidia GPU temperature. #How
   to install Graphics Driver
(NVIDIA)<http://ubuntuguide.org/wiki/Ubuntu:Feisty#How_to_install_Graphics_Driver_.28NVIDIA.29>


   - Install hddtemp first to monitor hard drive temperatures

sudo apt-get install hddtemp

GKrellM is a hardware monitor that can display CPU and GPU temperatures, fan
speeds, voltages, CPU load, network load, disk activity, disk temperature,
memory usage, and swap usage. The installation is very easy, and
configuration is just a few mouse-clicks. You can set alerts to warn you if
the CPU is too hot or there is a fan failure. The hddtemp utility works with
GKrellM to allow it to sense the disk temperature, as keeping your disks
cool (e.g. less than around 40C) will allow them to last longer than if they
run continually at higher temperatures (e.g. above 50C).

sudo apt-get install gkrellm

To run the program

Click Applications -> System Tools -> GKrellM

To configure the settings,

Right click on GKrellM -> Configuration

I was struggling with lm_sensors before, but it doesn't detect all of the
sensors on my computer. Later I found "GKrellM". It displays the GPU
temperature on my nVidia 6600 GT out of the box. GKrellM also has plugins
that show weather info, set reminders, etc.

*Add an audio alert (optional Step):* Here is how to play an audio message
when the CPU is too hot or a fan fails. First you need to find or record
your own audio alert files. (I use Audacity to record my own.) Then go to:

Configuration -> Builtins folder (Left side)-> Sensors -> Temperatures
folder (Right side)-> CPU -> Alerts Button

Paste ONE of the following lines into a Terminal window first to test the
sound. If you have two sound cards, you can use "-ao oss:/dev/dsp1" option
to route the sound to the second sound card. Modify the file path and name
so it points to the correct file. If you can hear the sound, then copy that
line to a command line text field on the GKrellM's Alerts window.

mplayer /home/myfolder/alert_messages/heat_alert.mp3
mplayer -ao oss:/dev/dsp1 /home/myfolder/alert_messages/heat_alert.mp3
