Ubuntu can monitor CPU and other system temperatures, fan speeds, and other system data using an application called lm-sensors. It can also show this information on your desktop or GNOME panel using one of several other applications. lm-sensor's homepage is http://secure.netroedge.com/~lm78/download.html This Howto was adapted from this Ubuntu Forums thread. That thread was written for Ubuntu 4.10; lm-sensors installation is significantly easier in all supported versions of Ubuntu. Make sure to read the Comments below for later versions of Ubuntu.

Install and Configure lm-sensors

1. Install the lm-sensors package (see InstallingSoftware).
2. Run sudo sensors-detect and answer YES to all YES/no questions. I generally use the ISA bus rather than the SMBus bus, your choice to this question!.
3. At the end of sensors-detect, a list of modules that needs to be loaded will displayed. Type "yes" to have sensors-detect insert those modules into /etc/modules, or edit /etc/modules yourself.
4. Next, run "sudo /etc/init.d/module-init-tools restart". This will read the changes you made to /etc/modules in step 3, and insert the new modules into the kernel.

Test lm-sensors

Next, you should test that lm-sensors works correctly. Run the "sensors" command and check the output. Example output is below:

w83627dhg-isa-0290
Adapter: ISA adapter
VCore:       +1.13 V  (min =  +0.00 V, max =  +1.74 V)

VSB:         +3.28 V  (min =  +0.14 V, max =  +3.07 V)   ALARM
VBAT:        +3.22 V  (min =  +2.06 V, max =  +1.02 V)   ALARM
Case Fan:      0 RPM  (min = 2636 RPM, div = 128)  ALARM
CPU Fan:    1117 RPM  (min = 1591 RPM, div = 8)  ALARM
Aux Fan:       0 RPM  (min = 1171 RPM, div = 128)  ALARM
fan5:          0 RPM  (min =  659 RPM, div = 128)  ALARM
Sys Temp:    +31.0°C  (high = +18.0°C, hyst = +96.0°C)  sensor = thermistor
CPU Temp:    +33.0°C  (high = +80.0°C, hyst = +75.0°C)  sensor = diode
AUX Temp:   +124.5°C  (high = +80.0°C, hyst = +75.0°C)  ALARM  sensor = thermistor
cpu0_vid:   +1.163 V

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +43.0°C  (high = +82.0°C, crit = +100.0°C)  

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +43.0°C  (high = +82.0°C, crit = +100.0°C)  

coretemp-isa-0002
Adapter: ISA adapter
Core 2:      +40.0°C  (high = +82.0°C, crit = +100.0°C)  

coretemp-isa-0003
Adapter: ISA adapter
Core 3:      +43.0°C  (high = +82.0°C, crit = +100.0°C)  

This sensors output shows four devices: w83627dhg-isa-0290 (motherboard sensors) and coretemp-isa-0000 through 0004 (Intel Core sensors). The motherboard sensor device has information on the voltages received from the power supply unit by the motherboard (in1-6), the fan speeds (entries with RPM), and various internal temperatures. As you can see, some sensors are obviously incorrect (e.g. AUX Temp and Case/Aux Fan); this tends to be the case with at least some of the sensors on most motherboards. The sensor output may be tweaked by editing the "/etc/sensors.conf" file. It is possible to correct inaccurate scaling too. For details check "man sensors.conf".

Get Sensor Information Displayed on your Desktop

Search Synaptic for either "sensors" to bring up a list of sensor-related applications, including xsensors, ksensors, and sensors-applet.

ksensors

Ksensors seems to work better for many people, and be easier to configure. Install the ksensors package (see InstallingSoftware). Start it from terminal with ksensors, and you should be able to choose which temperature, fan RPM, or other displays you want. To get Ksensors to start when your computer starts, go System menu --> Preferences --> Sessions, and in the last tab, Startup Programs, add ksensors. (or whichever sensors display program you choose to use).

sensors-applet

For a GNOME alternative, you can apt-get or Synaptic search/install of "sensors-applet", a GNOME panel applet that displays temperatures and fan speeds from lm-sensors. During installation, you'll be presented with the option to start the hddtemp daemon at startup. Choose "no" here if there was a sensor detected previously that reports your hard drive temperature, otherwise choose "yes". After installation, you can right click on any panel that you want to have sensor information displayed on, and click "Add to Panel...". In the "Add to Panel" window, there should be a icon with the text "Hardware Sensors Monitor". Click on this entry, then click "Add". You can change the applet's settings by right-clicking on the applet and choosing "Preferences".

Comments

In Gutsy the process to configure lm-sensors is much simpler. I installed lm-sensors and sensors-applet, ran sudo sensors-detect (and said yes to everything). It asks if I want it to automatically add the modules to /etc/modules, I said yes. Then restart to get the modules (one could do some modprobing, but just restarting is easier) . Then I added the sensor applet to my panel. -- SamTygier The original thread was written with Warty 4.10 in mind. The simple process seems to apply for Dapper, Gutsy, Hardy, and Intrepid, so I've removed the over-complicated cruft that used to be here -- Robert Wall

Jaunty, Karmic and Lucid

In Jaunty, Karmic, and Lucid, the procedure in Sam Tygier's comment works fine. Just open a Terminal (Applications -> Terminal) and type:

sudo apt-get install lm-sensors sensors-applet

Next, run sensors-detect. I answered "no" to the question about automatically checking the hard disks on the pop-up screen because I wasn't sure (as the instructions for sensors-detect state), and "yes" to all the sensor probes that follow.

sudo sensors-detect

Finally, restart to load all the sensors. Once back at the desktop, right-click on the top panel and choose "Add to Panel." Select "Hardware Sensors Monitor" and click the "Add" button, then "Close." Right-click on all the sensors that appear and choose "Preferences." Click the "Sensors" tab. There you can select/de-select all the relevant sensors and adjust their low and high values as well as set alarms if desired.
