    I have a 2.4 GHz Intel Core 2 Duo MBP - 13-inch, Mid 2010
    Running OS X 10.8.3 (12D78)
    I also use the NoSleep Utility to keep it connected and awake when the lid is shut.

    Recently, when I have the lid closed I have come back to find it hot to the touch with the fan running hard - the Activity Monitor says Chrome is using 90+ percent of the CPU. Last time I shut Chrome down and found it in the same state with iTunes using 80+ percent of the CPU while the machine is otherwise idle

    Any thoughts?

    Try it with both Chrome and iTunes shut down. They shouldn't be using that much CPU under normal conditions, whether the lid is opened or closed. Your issue is with the apps consuming system resources and driving up temps, rather than the lid being open or closed.

    I know the issue is with the apps not the lid - shutting them down takes care of the CPU usage, obviously. But they only start running so high when the lid is closed, neither of them does it when the machine is open and idle or open and in use.
