Hello. This is my first post, i got my first Mac 4 days ago, base model of the iMac 24" I am in "love" with this machine, damn its sweet!
Its VERY quiet, i would say whisper quiet. My external disk makes 2x more noise than the whole iMac alone! 😀 Even if i do some heavy CPU tasks, like encode video, the fans seems to stay at nice 1200rpm range.
Temperatures seem to float between 40-60c 🙂
