Hi all. Just bought a used Powerbook G4 12" 1.5 Ghz with 1.25 GB of rram. The computer is working great, but the fan fires up even when using Mail or Safari, and even if I close those apps it still keeps humming along until I put it to sleep. I downloaded Temperox to check things out. I ran a bunch of different apps at the same time, and temps get up to 56 degrees or so. I noticed that as it got hotter the CPU Core Voltage rose from 1.0 V to 1.17 V. Is this normal, or should the voltage remain at 1.0?

Also I noticed the rear left fan revs up to several thousand RPM, while the right fan stays at 30 RPM.

Any info would be appreciated. Getting a new (to me) computer, I want to make sure everything is working as it should.

Thanks,
Dennis
