Unfortunately, "d3p_ivvvidotnet" seems not to have read the detailed reference manual which is part of every download package.

The newest PowerBook models are fully supported by the application. A temperature of 100°C (212°F) for the internal sensor of the ATI Mobility Radeon 9700 chip is the correct and expected temperature, as designed by Apple and ATI. The sensor overview feature of the application also explictly notes that 100"C is the allowed maximum for this sensor location, as specified by Apple. So there is no need to "worry", and the displayed values are accurate.

It is known and also explicitly noted in the documentation that the internal hardware sensor of the ATI chip may begin to show inaccurate readings when Mac OS X reduces voltage and clock-frequency of the Radeon to avoid overheating. This is how the hardware and its protection features are designed, and not a problem with the application. For more information, you might want to contact ATI.

I hope this information is helpful to resolve this misunderstanding.
