    I just bought my first Apple product, an i-Mac 21.5. I love it except that a loud fan turns on after streaming a movie (netflix) after about an hour. If I simply turn off the computer for 5 minutes the fan turns off and I can resume streaming without the fan. - This has happened repeatedly in the week that I've owned the i-mac. I took it back to my Apple store for a checkup and they told me nothing was wrong. - Is this normal for new i-macs?

    Yes, it is normal for fans to ramp up if the machine starts getting hot.

    [removed content, as it was not correct]

    You could download iStat Pro to monitor the temperatures of the CPU and GPU if you want.

    Also have a look at Activity Monitor ( Applications / Utilities / ) and select All Processes and sort by CPU to see what the culprit may be.

    image below uses sorting by CPU as an example

    If it's Netflix it's probably Silverlight... but still CPU intensive.

    Thanks for that information. I can't use Netflix in my country, thus my ignorance on the layer of operation.

    Netflix does not even mention it on their homepage.

    Netflix uses Silverlight. I have not had the fan kick up from watching and or streaming video. That would kind of suck if you are trying to watch a movie.....
