CPU Speed VS Heating problem

I had the firmware upgrade on my 2.16 MBP and it has performed very well, the CPU speed cuts back and usually runs at 1333 mHz and the CPU temp runs about 50 to 60 degrees C. Recently it began running at 2167 100% of the time and, of course, the CPU temp is running in the 80 degree C region.

Same apps being used, no new software installed. What gives? I certainly would like to have it return to the older cooler running mode.

Thanks for any assistance or suggestions.

Perhaps you might try using Activity Monitor to determine the application that's using up the CPU...

No viable options to date although you may want to keep this in mind. Apple has made changes to the firmware and system management control so that you may safely utilize the performance you paid for. You may not notice it now although when Leopard is released, you may appreciate the maximum performance of your Mac with the current updates, as it is now able to run the more robust and demanding operating system of the future.

You probably have a rogue process causing processor usage and ultimately causeing yur processor to run at full speed 100% of the time. I would suggest using a tool like MenuMeters…

… and see what sort of usage you get at idle. You should realistically have less than 4% idle usage.
