I just got a 15" macbook pro last week and i've been noticing some issues with heat. Whenever I have the magsafe plugged in, the laptop will eventually get very warm (the processor temp reading 170 degrees or so). However, when it's not charging or plugged in, it mostly stays around 120-130. The weird thing is, even if it's not charging and the magsafe is just in, it will still get to those hot temperatures. They don't really bother me, but I don't want to damage my laptop, or perhaps it is damaged already. So, is this normal or ?
