I know there's a few threads here about temps, but I'm still concerned about mine. This is after about 50 minutes on Skype and the computer has been on for about 3 hours previously but just light surfing and email. Usual temps are lower, but as soon as I use Skype it jacks up like that. The fans don't seem to go any faster or any louder. My better half travels a lot for work so we use Skype a lot and I'm worried it'll damage my iMac over time.
