Nothing in PaperFacer's post sounds particularly bad to me. Mate, longer term experience would certainly be more telling, though. It's virtually impossible to predict how the machine will operate under a wider range of circumstances, but if the fans keep all the critical components cooler than their max. temp specs, then there isn't a lot to be concerned about. Some don't like fan noise, however. If you are one of those, then you probably already have your answer vis-a-vis a return. (Apps that "adjust" fan speed don't usually slow them down (to satisfy noise averse folk), they enable folk to adjust set points that enable them to run even faster earlier, so as to keep components even cooler than factory set points.) So, those apps are probably not the answer for folks that do not like fan noise.
Returning to the question.....Completely risk averse folk (like myself) would return the MBP, re-pocket the money, wait for a few months to let the smoke clear, and then re-evaluate the requirement for the horsepower of a 2011 MBP. Less risk averse folk would keep it beyond the 14 days, and hope that Apple stands behind its warranty.
