Use lm-sensors to read out I2C/ISA hardware (check temperatures, ...)

Many motherboards have electronic chips that control fan speed or measure temperatures. Some are connected via I2C, others via ISA. Most of them can be read out using lm-sensors on Linux computers.

Install the lm-sensors package using:

sudo apt-get install lm-sensors

Try to detect the chips (sensors) connected to your computer:

sudo sensors-detect

Query sensor status:
