Actually, IBM and Motorola specs say the G3 has an operating temperature
of up to 105C!

(Quite different from Intel's stuff, isn't it? ;^)
Before I read that, I used to worry myself when the heat-conducting plate
above the cpu was hot to the touch when opening the keyboard (which
probably means about 60C). As it is, you'll probably have to worry more
about the harddisk and other components.
Still, looking forward for a temperature monitor in pmud :-)
Thanks for your efforts,
Derek
