My iBook also becomes quite hot after some time of use in this season. In my case, the responsible is the hard disk. I use this daemon: http://mnm.uib.es/~gallir/cpudyn/ that sets powersave/performance modes dynamically (I do not notice any performance degradation, it works quite well). It also puts the disk in standby mode after a preset number of seconds without activity. You have to tune a little bit your daemons so that they do not make innecessary disk reads(*) too often (wich for me was the case of postfix, before switching to exim). In conjunction with laptop-mode (available in 2.4.21-ben*), it results in quite long periods of time with the disk not spinning at all. (*) If you use this laptop-mode, disk writes are not "too harmful" in this case, because they are delayed. All in all, the improvement in the temperature is quite noticeable. -- Kiko
