    It never happens with my MB. It happens with games, but not with movies.

    By movies do you mean DVDs?

    That's CPU bound so you're going to be hearing the fans once the processor heats up.

    my macbook is the new 2.16, had it about a week now, and the fan is pretty loud, when watching movies. if it's normal, then fine, but if not, what should i do?

    thanks

    What kind of movies are you watching?

    You might want to watch Activity Monitor while watching them as well.

    dvds mainly, too processor intensive?

    what is Activity Monitor and what does it do?

    thanks

    Decoding is software based and don't mistake the drive spin up for fans.

    A little louder than the sound of birds chirping outside your window but softer than a dishwasher running a rinse cycle @ 10 feet.

    ROFL!!!

    I know that my MBP makes a lot of noise when I'm watching movies.
    It normally happens after about 30 minutes of watching...

    Its normal. I watch a lot of movies on my MacBook, but I've started wearing headphones when I do and I don't really notice the fans anymore.

    my fan kicks on whenever i run aperture or even FireFTP in firefox. Some other progs as well. Am I doing anything wrong? Are there possible other programs running that I don't know about? How do I check?

    but doesn't it mean it's using a lot of resources? can the great core duo not handle it?

    of course it can handle it, just because it is powerful doesn't mean it throttle back and 'conserve resources' to give you average performance, it will use its resources to give the best performance possible.

    basically, you use cpu, cpu gets hot, cpu gets cooled by fans.

    if it 'couldn't handle' it you wouldn't be getting smooth playback.
