I just recently picked up a new 13" MBP to replace my late 2010 MBA. It was a great move as a lot of things have improved for me in my day to day use. One of the best things, is that it doesn't get insanely hot when watching Netflix or Youtube videos anymore. My old MBA would get close to 170 degrees (clean chassis and fan area, took it apart myself to verify) when trying to watch HD streaming videos and it always bugged the crap out of me that it was getting so hot. This new one however didn't get anywhere close to that. Maxing out about 110 tops on the memory board of all places. Now on to the thing I've noticed. After about I'd say 3 weeks of owning the MBP, it's started to get warmer. Now there is hot to touch heat coming from the top left of the keyboard casing. And to me that is absolutely backwards of what should be happening. It's no guess that manufacturers don't use the highest quality thermal paste when assembling a product but is the quality that Apple uses so bad that it actually gets worse after initial "bake in"? If so...it might be time for me to strip this sucker down and put in some work to keep this thing cool for years to come instead of just the first month. Has anyone else had this experience too? It hasn't gotten to the point where the fans kick on to sonic speeds but if unattended to, it might be on the horizon, no?
