Having built and configured your nice new machine, you may want to keep an eye on temperatures and fan speeds. The main package used to do this is lm-sensors<\/strong>, which can be installed using apt-get<\/strong>.<\/p>\n

sudo apt-get install lm-sensors<\/pre>\n
Although there is basic info<\/a> for older versions of Ubuntu in the Community Documentation<\/a>, there are very good instructions on this page <\/a>on compdigitec.com. Once you’ve installed lm-sensors<\/strong>, you can view data at any point by running the command sensors<\/strong> in a terminal window. The compdigitec article was published in 2008 and so still mentions a ‘panel’ as used to be found in GNOME 2. These are defunct in Unity, which comes as the default on Ubuntu 11.04, so if you want a GUI representation of your temperature and\/or fan data then Psensor<\/em> is probably the way to go. You’ll need to add a new software repository as it isn’t included in the standard ones; ubuntuguide.net has a good walkthrough here<\/a>. Unfortunately all the motherboard \/ chipset temperatures and fans are just labelled temp1, temp2 and temp3, so although you know which are your CPU temps you might not be able to identify the others.<\/p>\n

sensors<\/strong> didn’t pick up hard drive temperatures for me, but you can get those by running:<\/p>\n
sudo hddtemp \/dev\/sda<\/pre>\n
This assumes you have a SATA drive; for older devices, use \/dev\/hda\/<\/strong> in place of \/dev\/sda<\/strong>. For more generic information about your hard drive, you can run the similar hddparm<\/strong>, i.e.<\/em>:<\/p>\n
sudo hddparm \/dev\/sda<\/pre>\n
Both were installed on my system by default, but can be obtained using apt-get<\/strong> if required. Thanks to embraceubuntu.com for pointing these out.<\/a> Finally, I’ve put together a little script to pull the main information from my system into an easy-to-read few lines. Feel free to use and modify for your system as required:<\/p>\n
