    Can't tell if the sensor or fan is bad. Fan doesn't come on even when the processor is 60+C. The only good apps I've seen to either trouble shoot fans or to make sure it's on through a command is for the intel versions not for PPC. Anyone know of how to trouble shoot?

    To check if your fans are working at all, either try running the Apple Hardware Test that came with your machine (most likely on a separate CD), or try resetting the PMU. :)
