    Starting a few days ago, my 5 month old Macbook is showing higher than normal CPU temps. As I type, I have Firefox and iTunes open. The fan is running at a speed of 4500+rpm and the temp is 70+ Celsius.

    Again, this has just started a few days ago. I have been using it in clamshell mode with a monitor but now I am scared to leave the MB closed.

    Any ideas?

    Sounds like something is using your CPU.

    Open Activity Monitor - select all processes and then sort them to show what is using your CPU. Could be anything - Spotlight, an unfinished job....

    Have you tried a restart ??

    It is best to keep the lid open - even when in "clam-shell mode". Once it is running through the external open the lid and the laptop screen will stay off - until you sleep the machine or turn it off.

    So leave it slightly open and see if changes? I wouldn't use anything power intensive with the it closed because heat it partially dissipated through the keyboard.
