    I can confirm this behaviour with my G5 at 2,7 Ghz.

    MacOS seems to use some kind of CPUFreq thingie to lower the speed of the G5. There is no such thing on MorphOS and the CPU is always at 2,7 Ghz.

    Temperatures on MorphOS : 86°C is indicated for the 1st CPU (and 77°C for the second CPU). I don't know if it is accurate or not but the temperature is maintained at 86° by the fans (I can hear them constantly, not very loud though). I get this temperature thanks to the temperature sbar. I don't know if there is a more accurate software to check them.

    I installed MacOS X Leopard yesterday to see and, indeed, the temperature stays at 49-50°C when idle and jumps to 70°C on load (and fans start spinning louder).
