Temperature Monitor to just keep an eye on the temperature readouts. If your machine doesn’t have many/any additional sensors-or if those that exist aren’t of any value to you-then you can use Marcel’s freeware If I were to register the program on the mini, I’d gain access to the voltage, current, and power sensors on the CPU, as well as the RPM of the fan and the actual clock frequency of the CPU. On the mini, I can see eight different temperature sensors in demo mode. This seems like quite a lot, until you compare it with a desktop tower-Hardware Monitor on my Mac Pro lists a total of 55 separate sensors. On my MacBook Pro, however, there are 29. On my Mac mini (1.66GHz Core Duo), there are a total of 13 sensors available. Exactly how many, and what they sense, depends on which Mac you own: On my aging 12-inch PowerBook G4, Hardware Monitor found 10 sensors.

You may not have known it, but your Mac is chock full of sensors.

Hardware Monitor is a utility that reads and reports on the various sensors in your Mac. Do you thrive on information-lots of information? Have you ever tried to diagnose an odd system problem, thinking it might be heat- or power-related, and wished you knew more about what was going on inside your Mac? Do you like attractive graphs with lots of data points that might even be useful at some point in time? If you answered yes to these questions, then you’re an ideal candidate for Marcel Bresink Software-Systeme’s
