I'm the proud user of a 12' Rev A Powerbook. I'm also running OS 10.3.2. I'm also running Silent Night so I'm not troubled by the fan issue associated with OS 10.3.2. I love my Pbook to death but there's always something that's bugged me and that's how noisy the Superdrive is. The problem is during playback. It seems that immediately once it starts playing the fan kicks in at pretty much full speed. This occurs irrespective of whether the Pbook is operating from a cold start or has been running for some time. The strange thing is that I noticed that this problem only applies to CDs. DVDs are whisper quiet by comparison (there's a slight humming from the spinning but no fan - at least until the Pbook heats up). My first thought is that it had something to do with iTunes, however, not all CDs play as loudly as each other. Some CDs play with the fan running probably at 1/2-3/4 speed while for the rest the fan is howling. Nevertheless all CDs play much louder than DVDs so much so that you wouldn't consider playing a CD in a library or other quiet areas whereas a DVD would be fine. I also have a large CD and DVD collection so I can rule out faulty discs etc. Can anyone out there offer any assistance or explanation???
