Ubuntu: Sensor temperature monitoring with lm-sensors

One of the basic things you need, especially if you build your own boxes like I do, is to be able to watch cpu temperatures, voltages, fan speeds, etc. This is easily done with the lm-sensors package in conjuction with code which is available for most types of motherboards in the kernel. This is pretty straightforward, first off lets install lm-sensors:

# apt-get install lm-sensors

config the sesors
sensors-detect

Then , install gui monitor
# apt-get install sensors-applet
