Temperature Monitor
Learn more about your Mac
Next to measured readings, their history data, extreme values and the permissible limits for the sensors, other information about your computer can be displayed as well. This includes the processor type, processor and bus frequencies, manufacturing data, the S.M.A.R.T. verification state of your hard drives, connectors on Intel mainboards, and many other items.
The following screenshot gives you a first impression what's possible with Temperature Monitor (click to enlarge):

Number of displayable sensors will vary greatly depending on Macintosh model.
Sensor Support by Apple
Of course the applications can read out the data only if your computer is equipped with the necessary sensors, and if Mac OS X can access them without needing third-party device drivers. Beginning in summer 2002, Apple has begun to massively drive forward the use of monitoring probes in the PowerMac series, the Xserve series, and in portable computers. Some models are equipped with 100 and more sensors. But Temperature and Hardware Monitor can detect sensors on many older systems as well if they are available.
Temperature Monitor is designed to support sensors of Apple Macintosh computers released between August 2002 and October 2012.
