Hardware Monitor, which we have often discussed, is a program capable of giving results collected by the sensors of the Mac. Thus, on a Mac Pro, it gives dozens of results, ranging from the temperature of each CPU, through those strips of FB-DIMM and the rotational speed of the fan and even power consumption of major components.
Version 4.4 out yesterday adds support for latest MacBook Pro and MacBook Air, and also gives specific information on the Radeon 2600 and (Intel) GMA X3100.
The individual license is sold for 7 (+ tax), not a large sum for those who want to have this much information on their machine.
