I recently rescued a G4 MDD from going to the recycler at work. I couldn't have lucked out more. It is a 1.42Ghz DP with the Radeon 9700 Pro. My only concern is the volume of the fans and the temperature. I know these machines have earned the nickname G4 "Windtunnel" but I just want to make sure I'm not going to burn it out. When I started it up and started using it, I was getting about 58C while web browsing. That seemed a little warm while essentially idle. I opened it up, cleaned out several years of dust and removed the large HDD bay in front of the fan holding two extra drives I don't really need. This saved me a whopping 2C bringing me to an average of 56C. Should I be looking at replacing the Thermal Paste? I have never done that on a Mac and the idea of it is a little intimidating on a non-modern, non-ATX motherboard. Thanks!
