I got my new rMBP (early 2015 13") in a few days ago and I'm loving it so far. Although I updated my mid-2010 MBP with an SSD I still wanted a better screen and a better CPU. The only thing that's been bothering is the fan will occasionally start blazing. I play the occasional game of hearthstone which is really not a particularly demanding game and the fan will get much louder than it would ever get on my old MBP. It's been throwing me for a loop so I've installed some hardware sensor software and these were the results (in Celsius) during my game of hearthstone: Afterwards as I quit the game and it was cooling down I took another screenshot (in Fahrenheit this time as I think most people here would be more familiar with that): Now if I'm reading this correctly I think I should be worried and consider returning it right? The MBP doesn't feel particularly hot to me but then again I'm used to slightly mistreating my old MBP causing it to run a little hotter. I'm just wondering what you guys think about these statistics?
