Hey all, question regarding the internal temperatures on my mid-2010 MBP. It' running the 2.4ghz I5 processor with 4gb of RAM and the stock Intel HD Graphics 288 MB. A few months ago when Diablo 3 came out, I thought about buying a new computer expressly for gaming, but didn't because the MBP seemed to be completely within the specification list for the game. I installed the game and played it a ton on my MBP but noticed it heating up right away. I downloaded a temperature gauge to see what the temperatures were of the internal components. All of the fans were running full blast and the temperatures had all increased, most noticeably the "GPU Diode (Analog)" temperature, which had broken 125 degrees Celsius. I ended up buying a desktop and making it my primary gaming computer, but would really like to game with the mbp, especially since I have to travel for work every once in awhile and it'd be nice to game when I'm bored in a hotel, but only not if it is going to cause damage. The last couple of days I wondered if upgrading the ram might just cause the computer to not have to work as hard, maybe not taxing the Graphics Card (what I assume GPU is). Any ideas if that would in fact help? Sounds like my MBP can have up to 8gb as opposed to the 4gb that is pre-installed and the prices aren't that expensive to get two 4gb ram modules (or whatever they're called). Today I decided to run the temperature app before, during, and after playing diablo 3 on my mbp. As expected the baseline before running D3 was lower for the most part than the temperature readings during running D3, and the temps went down after quitting the game immediately, all but one, the stupid GPU Diode (Analog) which went from 127 before to 67 during, then back to 127 after playing. All of the other sensors read as expected but this one was weird going backwards from what I thought would happen. I guess my questions are: 1. Why would this happen? 2. Is there any fix for it or since the graphics card is probably soldered in am I out of luck and is my $2k MBP about to turn into an expensive table cloth for my coffee table that it usually sits on? 3. Is it worth upgrading the RAM or does the GPU heating issue make that a moot point? Attached are the pics I took of the temperature readouts for reference.
