Hi all I recently purchased a rMBP 15" 2.7 i7 16g and have been having some concerns about the fans. The fans start up very randomly when web browsing or searching a large pdf file. All while around 35-40C and fan speed going up to almost 6k. Also another concern is how loud the fans are suppose to be? Yesterday while sitting in a classroom lecture my rMBP decided to ramp up and they would not slow down and had no choice but to close my laptop as I did not want to disrupt the professor lecturing.(fans sounded like a mini jet) I have done two SMC resets this morning. Any input from other fellow rMBP holders would be appreciated. Thanks.
