One of the things I noticed in going from my '10 MBP to the '11 MBP 13" was the amount of time the fans were running and the average temperate when doing light activities. My average "email and light browsing" temperature was showing around 45 - 49 C. I noticed the fans would kick in and back off when processor activity was slightly more intense. I also noticed in gaming (Star Trek online through Wine - CPU intensive as it is) it was hitting 90 - 95 C. Based on the iFixit tear down of the 15" 2011 and the ridiculous amount of thermal compound they found on the Thunderbolt chip, I thought I'd go ahead and do the cleanup on mine and apply the correct tiny amount of Arctic Silver 5 compound. I performed the tear down of my own and the results were what I expected. There was a ridiculous amount of compound on the Thunderbolt heat sink and chip. There was also a random / uneven amount of compound on the CPU / controller. I carefully removed the excess compound from all the heat sinks and chips and applied a thin amount of Arctic Silver 5. Put the machine back together and have been monitoring my temperatures again. My light browsing and email usage is now showing between 37 - 45 C, spending most of its time around 39C. My in game high CPU temperature has dropped to 83 - 90 C. I also like to control my fan a little more closely than SMC allows out of the box, so I wrote some scripts to allow me to set the fan to 1800 RPM max for when I'm doing simple tasks, and crank up the max when gaming. The result is that this thing is now whisper quiet and cool. I'm sitting here now uploading and doing this post staring at the 38C temp with the fan running @ 1800 RPM max. I will post updated results as this compound settles and this thing sees some more extended usage today. In short - the Chinese assembly line once again had an excess of thermal compound that they felt necessary to glob all over the MBP internals.
