Lm-Sensors

LM-Sensors is a GPL / Linux program that provides some essential tools for monitoring the hardware health of systems containing hardware health monitoring hardware such as the LM78 and LM75. This program is a bit on the cumbersome side as far as configuring and running but after she's installed she workers great.

Downloading/Installing
yum -y install lm_sensors.i386
 * On Fedora run:

Configuring
/usr/sbin/sensors-detect Sensors-detect will now ask you a bunch of questions regarding the type of system you have. The great part of Sensors-detect is if you just answer yes to all the questions you should be good to go. Once Sensors-detect has ran you will see an out-put close to this. To make the sensors modules behave correctly, add these lines to /etc/modules.conf: alias char-major-89 i2c-dev To load everything that is needed, add this to some /etc/rc* file: modprobe i2c-i801 modprobe lm85 modprobe eeprom /usr/bin/sensors -s # recommended If you have some drivers built into your kernel, the list above will contain too many modules. Skip the appropriate ones! You really should try these commands right now to make sure everything is working properly. Monitoring programs won't work until the needed modules are loaded. Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): yes You will now wont to follow the cut here and see is she works.
 * Before you can run lm-sensors you need to configure it to run on your system. Start out by running:
 * 1) cut here
 * 2) I2C module options
 * 1) cut here
 * 1) cut here
 * 2) I2C adapter drivers
 * 1) Chip drivers
 * 1) sleep 2 # optional
