So, I came across something rather interesting while trying to run Rember on my MBP:
Note the CPU diode temperature. It's possible that this is a glitch in hardware monitor (though smc fan control reads the same), but it's also possible (and more likely, in my opinion) that the diode is close to the area on the cpu die that deals with memory access, thus the large temperature disparity.
I think this is backed up by the fact that I have never, ever, EVER seen the bottom or top of this machine get anything like as hot as it did. I actually burned my hand on the bottom case (it's still a bit sore several hours later).
Interestingly, it'd jump up to almost 130*C (the screencap says 123, I saw as high as 127), then it'd drop down, then jump back up again. I don't know if the processor was throttling or just what. I really need to install XP on this thing and run the Intel Thermal Analysis Tool.
Anyone here willing to put their MBP on the line and see if they can confirm that my 127*C reading isn't abnormal while running Rember? Or anyone that's got bootcamp installed that's willing to run the Intel TAT and see what it hits on that?
I think this bears some investigation... If the CPU in this thing is really hitting almost 130*C due to executing a specific application, then Apple needs to do something about it. There is absolutely no excuse-none-for a computer's cooling system to be so totally inadequate that a program can load a chip (be it the CPU, the GPU, the northbridge or the RAM or anything else) to the point where the chip actually exceeds its maximum operating temperature specification.
//edit: I should add a note here that testing this out, if the cpu is actually exceeding 100*C, could damage and/or kill your MacBook Pro.
