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 ** Sent via the linuxppc-dev mail list.

G4s come in a variety of temperature specs, and many of them are only rated up to 65C. You'll have to read the markings on the package to work it out. - Adrian Cox ** Sent via the linuxppc-dev mail list.

There are multiple temperature grades. Desktops usually use parts rated for 65 C, maybe 85 if you're lucky. Apple's early Wall Street G3 laptops used 105 C parts (and needed it), later ones with better cooling may have 85 C. Tim Seufert ** Sent via the linuxppc-dev mail list.
