I have a 17in macbook pro quad 2.3 Ghz, I ran skype for the first time last night and the temp at one point hit 80 C. Can someone please explain why this happens? My CPU% (iStat) was around 9 yet the computer got fairly hot. If the 13 inch macbook pro's with less specs can run this why is it so necessary for a more powerful computer to get so hot? You'd think with more power it wouldn't need to work as hard. Do the upgraded HD facetime camera's add to processing? I switched to gmail video chat for a bit and my temps topped out at only 70 this time. I've heard of bugs in Skype 5 for mac but I'm just wondering why a quad core needs to get so hot to run some video. Thanks!
