I decided to create a thread comparing PPC Mac temperatures. I talked to a couple members about temps (namely Erik and Altemose), and had a random idea to create this thread. Anyway, here are my PB G4 and iBook G4 temps, the first two pics being my PB, idle, then after 10 minutes of normal use, and the last two being my iBook, again, idle, then after 10 minutes of average use. I used iStat Pro, and measured in Fahrenheit. Feel free to post and compare!
