1) Questions and Answers : Macintosh : running hot (Message 2821) Posted 3 Sep 2004 by old_user10811 Post: I have this problem on an Apple 12" PowerBook G4. I guess once the system sees a high load on the CPU it starts the fan before the CPU gets too hot. However my system 'idles' at around 45.3 deg C and with a high load shoots to 55.9 deg C in a few seconds. I've not left it running for long periods under full load simply for this reason. A useful feature would be to have a way to limit the CPU usage* for the client - say 'Limit load to 25% of CPU', I know this will effectively lower the computational power of the system but would help for those of us who don't want to cook our lunch on our machines! *apologies if this feature exists and this is a case of RTFM.
