I recently picked up a 2012 Retina MBP 13" with a broken screen that I've been using as a desktop until I can get the screen repaired (or do it myself.) I've noticed that when doing something as innocuous as playing HD video the temperatures can get quite high. Now that is with 12 or so Firefox tabs open, and Mail, Word, iTunes and few other programs idling in the background. Despite that CPU usage doesn't seem to be going over 60%. Things are a little better if I close everything except Safari, but temps still hit 93ºC when *just* playing Youtube video. Is this normal? I've heard that MacBooks run hot, but that seems a bit much. Does it need to be blown out with a can of air? Do I have to remove the bottom (with its lovely pentalobe screws) to accomplish this?
