I am thinking of running some video demos off of my macbook pro. It is a newer 15" 2.6 ghz core2duo. The video in question will be h.264 running at a fairly high bitrate using VLC. The point is, the CPU will be fairly pegged. So my question is, how will the computer behave if I put this workload on it, for hours at a time, and close the lid ? Two specific questions: - will the fan run extremely loud ? - any danger of overheating / problems ? Has anyone done this - perhaps watching a blu-ray rip while attached to a TV or something like that ? Comments ?
