Hey, I have a PowerBook G4 15" 1.67 ghz model and it seems to run a little warm at times so I installed istat menu to check everything out and I am getting some odd fan activity the fans set at 0 rpm until my computer gets to 60 C then at that point both fans kick in really fast Well over 1000 rpm then they both stop once the computer gets down to around 40 C... My question is, Is there a Program or a terminal type mod that I can have the fans running all the time but slower so that my computer doesn't get this hot?
