    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!

    It's normal. Skype is a resource-hungry app. Your temps are well within normal operating limits. Your Mac will automatically shut down if temps get too high for a period of time (around 105C/221F). Unless that's happening, don't worry about your temps.

    High temps are perfectly normal, as searching the forum with Google will reveal:

    I really dislike skype 5's video now. It does get overly hot and the CPU usage is pretty over the top IMO. I switched over to facetime for video and it's a lot more pleasant to use, especially without the fans going. My buddies could hear the fans going when I had skype video haha. I do use skype for audio though and that's been okay.

    I've noticed Skype is a rather common complaint for it's heat. At least with skype 5, I don't remember it being too big an issue before though. It must have to do with some coding with skype's video vs ichat's or facetime's.

    It's not the high temps that bother me, I understand when converting video or photoshopping for the temps to get high. But skype? Aka video chat that iphones can do? Come on, it makes no sense.

    It makes perfect sense. Skype is a multimedia app and is well known as a resource hog. Video chat is CPU/GPU intensive.

    Is skype absolutely abysmal for everyone else?

    It's funny, i've noticed it too. Such lo-res picture making a high-end machine sweat couldn't be good software design imo.

    Skype makes your computer hot because the software is not optimized for Quick Sync on your processor (specialize hardware for video encoding); therefore it needs to use the general processor to do the encoding which increases the heat output. On your phone, the code is optimized for encoding hardware and therefore it can run efficiently.

    Skype 5 is garbage on OSX. All of the testers were vocal about the problems during development, including performance and the horrible backward leap the UI took. Unfortunately they were ignored.

    As well as terrible performance in low-bandwidth areas. Where I have been living the last 4 months, bandwidth is in very short supply. The older versions of skype would struggle a bit with video, but I expected that. Now with the new version, it drops and it has become impossible to have a conversation without it dropping every minute or two, on voice only.
