Hi all, I have a 2013 11" Air with Core i5, 4gb RAM. I dont do much heavy work, just an iMovie project like once a week or less for YouTube; and I also play Lego Pirates of the Caribbean and Lego Star Wars the Complete Saga and Minecraft, around once a week, sometimes more frequently. When playing Lego Pirates of the Caribbean, or after working for a while in iMovie, my Air gets hot and the fans turn on. It is after around 10 minutes for Lego Pirates of the Caribbean, and a bit longer for iMovie; for Lego Star Wars and Minecraft, I can go for a long time without any fans or noticeable warmth. I know this is probably normal, but is it a bad thing to do this to my Air? Or is it just normal and nothing to worry about? Thanks in advance, JerTheGeek.
