If anyone can help me with this fairly quickly. Last day to return/exchange my new MBA 2015 and it's during finals so I'm kind of in a rush. I recently upgraded from a mba 11.6 2014 to a mba 2015. I needed the extra screen size. However, this thing surprisingly runs hotter than the 11 version. Initially it was at random times. No load on the cpu, it would get hot. I think it was due to the charger being connected and it seemed especially bad if the USB port was being used as well. It kind of got better, I ran down the battery a couple of times and that seemed to help. Now there's a little rhyme and reason to it getting hot but the CPU load will only be at 30%-50%. It bothers me because a lot of the time I use it on my lap. And comparatively, the 11.6 would get hot but only during strong loads like 75% and I could hear the fan come on. The rest of the time it was cold. This one gets cold but less often. It's seems like most of the time it's just slightly warm. Also, I don't think I've heard the fan once. Does this sound right? When I say hot, it's not like burning but yeah it's hot. Also, the first thing I noticed opening the box was a kind of strong gas smell. It seems like others have had the same experience with this new model. I figure it was because it was just released from the factory. I still believe that but it could be taken into consideration. I've had so many iPads, iPhones, MacBooks none had the smell to them.
