Hardware Monitor Widget Edition
Hardware
Monitor Widget Edition is the Dashboard version of its "bigger brother" Hardware
Monitor. You need a working registered copy of Hardware Monitor in order
to fully use this widget. The applications are designed to give you access
to all sensor readings Mac OS X uses to monitor and cool your computer.
The widget allows you to select two of your computer's sensors which should be displayed via Dashboard.
Unlike other widgets, Hardware Monitor is capable of processing the hardware calibration data Apple stores individually into each G5-based computer. So it displays the exact readings Mac OS X internally uses for cooling control, not just an "educated guess".
Hardware Monitor Widget Edition is electronically distributed software. You can download the product and test it before you decide to purchase an unrestricted usage license.
