    The temperature depends on how CPU/GPU-intense the apps are that you are running. An idling MBA stays fairly cool, obviously.

     

    Activity Monitor (under Applications -> Utilities) can tell you what draws which resources and how much.

    It gets hot even when it just sits their on my desk.

    When it gets really hot the free ram space goes from 60-80% to 0-11% free witch is annoying when I want to do anything because its just way to slow

    Again, it's predominantly the CPU/GPU-load which causes the temperature to be lower or higher.

     

    Of course, if you run multiple apps or apps that require huge amounts of RAM but you're low on RAM, the CPU will be busy with swapping data back and forth in between RAM and SSD, too.

     

    If it stays hot in what you think is idling, maybe it isn't idling but running processes "silently" in the background. Again: Activity Monitor, best the CPU tab, and the table sorted by % CPU descending.

     

    Before you ask: No, you cannot upgrade the RAM in an MBA since it's firmly soldered onto the logic board.

    Yeah I under stand I can't up grade the ram I got 4gb in stead of 2

    Theirs nothing running in my dock so if theirs stuff running in the background how do I stop them

    No one can help you if you don't read their posts. I repeat:

    You can quit processes there, but that way you can stall your machine, eventually. It's smarter to find out if the active, resources-hungry processes are necessary, and if not, what started them and go to the cause to avoid them getting started in the future.

     

    Before you ask: In case of doubt, googling a process' name may help.

    Yeah I should have read it better sorry but thanks for all your help
