    So I've had my MacBook Pro for a couple of days now, and I'm loving it. But today when I was using it laying on my bed, I realized that the fans became really loud, something that hasn't happened before in the couple of days I've had it. I Did have several programs open and was using the camera for video chat, is it because of that, or because of having it on the bed, because I know i had a similar problem with my previous PC.

    Probably using the webcam. That uses a lot of power, and when you have it on the bed, it doesn't let it dissipate heat like it's supposed to. Easiest way to fix that is to find a book to set it on. It may still heat up, but not as much

    Watching streaming compressed video is a relatively intesive process, especially if using flash. Your behavior is to be expected.

    As far as the fans go, let em work. If you have multiple programs open, lots of flash (youtube videos, games), or are doing heavy processing, the fans are going to ramp up as the temp and voltage elevate, which again is normal.

    DO NOT place your machine on a surface like a bed, high carpet, towel etc without something like an iLap, books or something to elevate. This will block the airflow of your machine. The machine will shut down once it reaches it's thermal threshold, but you could still end up burned.

    As said before, Flash is used on most video watching websites and Flash is highly CPU intensive.


    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

    You can also use iStat Pro to monitor your temperature and fan speed.

    Not if you're using HTML5 on Safari. That's how Apple push people to develop HTML5:apple:

    I hate stuff that requires flash just for that reason. The fans in my MBP start to go nuts when I have flash running.
