    So normally my Macbooks fans are hardly on and it runs really cool and quiet but this morning I turned it on for like 10 minutes and then off again and the fans were going crazy. Then when I got in from school, I turned it on liek normal and even now with just safari running the fans are goig wild. any ideas as to what might be causing this? I have had to turn off by holding the power button a coulpe of times b/c it wouldn't wake from sleep. what is it that I could try and reset and how do I do it? are there any risks? please help. I can't afford for something to go wrong.

    Make sure to check the Activity Monitor to see if any other programs are running. My mom had the same issue, and realized that she had Excel frozen running in the background. Once she Force Quit it, the fans wound down.

    just did. I only have safari running and other then a widget and a tablet driver(both of which I just quit) everything in activity monitor is Intel. I am lost.

    I also just held down at boot command+option+p+r whatever that does and its still going crazy.

    how old is it? Have you tried restarting?

    If you have tried restarting, one diagnosis would be a melted/broken thermometer cable. If it's in warranty, take it back and get them to have a look at it.

    Hope it all works out well for you :)

    It could just be random I guess. I hope it is. I have only had it for about 5 months so if it carries on I acn still send it back can't I? Maybe they willl replace it with a SR macbook! OK. Thanks guys. I'll see how it goes and go from there. :)

    What is CPU usage like? (e.g: is there a process that is stuck and hammering it?)

    What is the temperature on the CPU? The fan algorithm will step the speed up when the CPU hits 80C.

    Check for blockages around the vents on your laptop.

    reset PRAM

    reset the pram and it will sort out on both macbook and macbook pro
    just hold apple-alt-p-r at start and wait until you the mac reboots 2 times and than let go and that will sort it out

    yeah I have already tried that. It didn't seem to stop the issue. I don't know what could be up with it.

    You're still within your warranty period. Have Apple fix it.
