To lay the groundwork I have a baseline 13 inch MBP. i5 and a HD3000. Nothing too fancy. So I'm running the machine in bootcamp, Windows 7 of course, and I'm playing games. Nothing too demanding; Portal 2 in medium settings, Torchlight in low, Oblivion in low... but I have an application on the side that shows the varying temperatures inside the machine. What do I see? The 1st and 2nd core hitting 93+ every single time I start up and play a game. Doesn't matter if it's Oblivion, Portal 2, Torchlight, in ANY setting. Low, medium, high, it plays them all flawlessly but obviously the CPUs are burning up. Because I just got the machine two days ago, I decide to freeze some water in a bag of ice, make it as flat as possible, and that's what my MBP is sitting on right now: A flat block of ice that's about the same size as the MB. What are the results? The cores are STILL 90+ C while the rest of the machine is pretty cold. The bottom is cold to the touch; the only hot places are barely in the top left corner and above the airvent, below the MacBook Pro logo. This leads me to believe that the CPUs are isolated in MB to allow them to run hot while leaving the rest of the machine out of danger of overheating. Any thoughts? Or maybe I have a bad MBP?
