Here's another thread asking for normal MBP operating temperatures since I cannot find sufficient information about the late 2011 13" model. My laptop idles at 55C and goes from 65-75C when browsing the internet through Firefox. When watching a Youtube video temperatures hit up to 85C. So.. what exactly are the nominal operating temperatures? I know MBP has no exhaust but dang.. 80C is just way too hot. I'm sitting here programming and looking info up on the internet and the laptop is way too hot for my lap... First time buying a MBP for programming and engineering design. Should I be concerned with this issue? It doesn't seem feasible to have a laptop that runs this hot from normal web browsing. Thanks.
