Wait! Before you at another heat-related thread, consider the following... Reading through the last (closed) thread, I decided it would be fun to peg my CPU usage and see just how hot things would get. Take a look at this. I also tried playing back three H.264 videos from the Quicktime gallery at the same time, along with iTunes playing music with the visualizer active. CPU temps were in the mid 90s with the fans running ~5000 rpm. But then suddenly, Quicktime player unexpectedly quit. I am able to reproduce the problem. Is it possible this could be heat related, or something else? Any MBP owners up to running this little experiment? Or iMac, mac pro, Mini, MB owners for that matter?
