that sucks I've been on skype the past hour and the temp has hung around 57C and fans are at 2000RPM. I am on 13" i7 though but my rans love to get loud on load, but it stays at 2000RPM otherwise. I'm also streaming an .asx video in VLC player, no problems. I would def get your machine checked out.
*edit* I started doing video and it went up to 5000RPM ish to like 70C ish so yeah video will heat it up..
What version of Skype are you running?
I am wondering if the cause of the CPU load has anything to do with the new version of Skype. I am on the new version, 5.0. And like the other person in the post above, I am having major CPU load with Skype. Right now Skype is avg around 90% CPU load in Activity monitor. What I don't get is why overall CPU load is around 12% User, 2% System, and 88% Free, but the CPU temp is still so high.
I just bought the 15" with the upgraded CPU to 2.3(Apple store retail units w/ non-glare require CPU upgrade and I have edu discount). I was hoping that due to the major CPU efficiencies of the Sandy Bridge CPUs over last year's Core I's, that CPU temps and overall CPU load will be better. I hope I either have a bad unit or there is some optimizations I can make w/ Skype to improve this condition. This is my first Mac coming back from PCs(and before this had the first unibody aluminum Macbook). If indeed the Sandy Bridge CPUs on Mac do not perform as well as the advertised hype, I will be going back to PCs. The premium price over PCs would not be worth it.
