Hi I just got my Macbook Pro 2.2Ghz about a week ago. I have since installed OS X 10.5.1. I noticed while playing a music video in itunes. my fan's went up to about 6000 RPMS but the computer wasnt hot or overheating it only stayed that way for about 1 or 2 minutes. Is this normal ? I also have another MBP 2.2Ghz and the fans never came on this high.
