    if it's not over 100C, it's not "overheating". it's just warm/hot. it's fine.

    What temps are you registering?

    Are you using any fan management tools?

    Fan controller


    Overheating and hot to the touch are two different subjects. Try smc fan controller, you install it and it lets you manually control your fan speeds. This will solve your heat issue, but be aware that increasing the fan speeds means decreasing the battery life. Also 19-31 tabs is a huge memory hog, so if you do not have adequate memory, then it will bottleneck your computer and makes the CPU usage go way up.

    no, and i attached a pic :)




    and i'm sharing connection to PSP and magic mice


    and i don't intend to make my fan RPM higher, i'm intending to make the temperature lower

    um it's hot (mah skin is burnt)



    btw, where are the multiquote button :confused:


    and sometimes all the temp (not incl battery) goes up 50 celcius or more :O

    Tried what?
    If your CPU is at 78% usage, of course it's going to be hot. It's perfectly normal.

    lol. those temperatures are perfectly normal for a MBP. there's nothing wrong with your computer.

    /thread.

    As a higher fan speed gets more cold air to the internals of the MBP and gets the hot away from them, a higher RPM will result in lower temperatures.

    Are you sure?

    To quote several posts, use the [​IMG] button (multi-quote), the button turns red if you have selected a post, it then looks like this: [​IMG].

    oops, i tought mroogle was google lol

    the thing is that this macbook is running (i think) light apps most of the time, and i use 78% CPU?? :eek:


    hmm, maybe i'm thinking of uninstalling istat (it's trial, but has 9800 days left :D)

    iStat Pro, iStat Menus or coconutBattery will track temps, among other things. iStat Pro is free, so there is no trial period.

    Again, your temps are perfectly normal. You have nothing to worry about. Many have run as high as 105C without their Macs shutting down, which it will do if temps get too high. It won't damage your Mac.

    Dude. If you run 100 light apps, that's still a drain on the CPU.

    Are you for real? It seems odd to be posting concerns about temps that you can easily see are normal, on an old machine, while saying you have a new one but aren't using it...

    Just curious, regarding your signature, your workplace blocks Google?

    78% is fairly high CPU usage.

    I've got Finder, Lotus Notes, FireFox, Things, Activity Monitor, RDP, Adium, Preview, Excel, Word, and VMWare Fusion (running an XP machine) open and my CPU usage (on a slow Mac mini) is only 16%.

    The more you use the CPU, the more heat the CPU generates.

    If you want to figure out what application is using your CPU, use the Activity Monitor utility in your Applications > Utility folder. Set it to "All Processes", and then click the CPU column so it shows a down arrow.

    No, it blocks Mroogle (that's what my quote actually says).

    It's sarcasm, based on me getting tired of things like the following:

    Me - Hey everyone, how's your day going so far?

    Others - Please try Mroogle before you post questions that may have already been asked at some point in the entire history of the internet.

    (And yep, I know MRoogle is really just Google, tailored to MacRumors).

    Yes, I know it says that, but you know why I asked.
    I understand completely.
    That's why I asked. Thanks for satisfying my curiosity.

    i wonder about the plastic strip, is it causing it to overheat?

    Which plastic strip? Do you mean the black hinge between display and body?

    And again, your Mac is not overheating , just your CPU is in use by a lot of processes. When idle, my MacBook was around five percent CPU usage and even with several applications open and some Menu Bar items.

    Maybe you need to decide what to get rid of in terms of CPU eating processes.

    Btw, you can print (CMD+P) your Activity Monitor Process list as PDF and attach it here as PDF. Maybe we can take a look at it. Just remember to show ALL PROCESSES and sorting it by Process Name.
