I have a macbookpro, 2.66 ghz intel core i7 with 8 gb ram. I have 2 video cards from what I can tell, that are listed under my system profiler: The Intel HD Graphics and a NVIDIA GeForce GT 330M. When I play world of warcraft on Bootcamp, my fans kick in after about 10min when the temperature gets high, but it is no longer enough to keep my graphics card from crashing. I get a bunch of colored squares streaking across my screen and the laptop either recovers right away, or has to force a restart. I am thinking that either my graphics card has finally had enough and can no longer handel the heat, or my macbook is no longer cooling properly. Are there any other ways of keeping it cool? My fans will run at full speed and I have a cooling stand, but neither are enough, it still gets too hot to touch.

MacBook Pro, Mac OS X (10.6.8)

    Mid-2010 15" model?


    Mid-2010 15" MacBook Pros - the bad NVIDIA GPU


    If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.


    Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:


    Kernel Extensions in backtrace (with dependencies):          com.apple.GeForce(6.4.0)@0x82ac4000->0x82b7afff             dependency: com.apple.NVDAResman(6.4.0)@0x834a0000             dependency: com.apple.iokit.IONDRVSupport(2.2.1)@0x82fd3000             dependency: com.apple.iokit.IOPCIFamily(2.6.5)@0x7a802000             dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000          com.apple.nvidia.nv50hal(6.4.0)@0x83c05000->0x84019fff             dependency: com.apple.NVDAResman(6.4.0)@0x834a0000          com.apple.NVDAResman(6.4.0)@0x834a0000->0x8378dfff             dependency: com.apple.iokit.IOPCIFamily(2.6.5)@0x7a802000             dependency: com.apple.iokit.IONDRVSupport(2.2.1)@0x82fd3000             dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000



    Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…


    So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. They should be more than willing to install a new logic board at no cost. I have no idea why this faulty GPU is making the headline here on the MacBook Pro forum so often now - could it be because Mountain Lion is just bringing the issue to a head more readily? I don't know - I only know that we're seeing more and more of these kernel panics of late.


    Good luck,

    I am thinking that either my graphics card has finally had enough and can no longer handel the heat, or my macbook is no longer cooling properly

    If your thermel sensors aren't working properly/fans aren't functionally properly, then you could damage your logicboard at temperatures above ~210 F according to intel. Not sure about the discrete GPU (nvidea's) thermal limit, though.

    I get a bunch of colored squares streaking across my screen and the laptop either recovers right away, or has to force a restart.


    This sounds like a busted GPU.


    Are there any other ways of keeping it cool?

    Download smcFanControl for Mac

    Download iStat Menu as well to read the actual temperatures. "Hot to the touch" is too subjective, not quite sure how to convert that into C or F ...

  • samsonaa3 Level 1 Level 1 (0 points)

    I downloaded temperature reader and my temps will hover around 80 Celsius with spikes to about 100c. My fans are working as they should, they max out at about 6000 rpm but is still not enough, and the added cooling stand does not help either. It is a mid 2010 macbook pro. I mentioned earlier that this happens on Bootcamp, but it also happens on the osx as well. Is it worth it to get the hardware, possibly the gpu, replaced? I have no apple care so I don't know how much that would cost, I am assuming quite a bit though.. Just out of curiosity, would updating software help the issue? I have osx 10.6.8, might upgrading help? I spent all last night updating windows 7 and there ended up being an upgrade for my graphics driver, in the past, updating the graphics driver has helped, but that no longer seems to be the case.

    See if this Apple Repair Extension Program applies:

    To replace the GPU will require replacing the entire logic board and that will cost $800±. and that is probably not your problem.


    The temperatures that you are reporting may not be out of line for the applications that you are using.  Thermal shutdown will occur at about 105° c.


    Open Activity Monitor and set it to show ALL PROCESSES and %CPU to display values from high to low.  What applications are using high CPU percentiles?  Post the display for evaluation like this from my MBP:

    It may very well be that you really do not have a temperature issue and the MBP is operating as 'normally' for the given conditions.

    Here is the activity monitor with wow running, though only at the log in screen. I am not at a place where I can have the game fully playing right now but I would assume that it takes up quite a bit of my cpu usage. Is it possible that it is being maxed out? I am not sure if this could be the issue because I have been running wow on this comp for a good 6 moths now, and only now is it starting to crash my computer. Also, it very well may be possible that my temperature has hit 105 celcius but because it crashes, I am never able to check the stats at that moment. Is there a way to check the temp settings of a previous time so I can check the temperature at the point of the crash after it happens?

    I have seen graphs from temperature recording applications but I do not remember the names.  You might do a search for one.


    WOW is taking a fair amount of CPU resources, but there is nothing unusual in that.  What were the CPU temperatures when you made the screen shot?


    Google Chrome is the worst browser you can have on a MBP.  That may be a contributing factor to your temperature situation.Get rid of it.  I use Firefox, Safari and Opera.


    If you shut down WOW and Google Chrome, what are the CPU temperatures?



  • samsonaa3 Level 1 Level 1 (0 points)

    Without any chrome or wow running my temps sit between 30-60c which seems pretty normal to me, it is only when I run wow that it jacks up. The temperature app I just downloaded records history and Ive uploaded a shot of that. When I open wow you can see the temps rising. Again, this is only at the log in screen, and judging by feel, my comp is not nearly as hot at log in, as it is when playing, I will post temps during a crash tonight, hopefully it will give some insight. Thanks for your help!

    See Clinton's original response. The NVIDIA GPU is clearly causing the issue.

  • samsonaa3 Level 1 Level 1 (0 points)

    Can you please explain Kernel Panics? I have tried to do some research and it doesn't seem like I have any of those errors showing up on my computer whenever it crashes. Is this a mac only issue? I have the same problem occurring on both osx and bootcamp windows 7

  • OGELTHORPE Level 8 Level 8 (41,045 points)

    Perhaps these two article will answer that question:
