    Wait! Before you :rolleyes: at another heat-related thread, consider the following...

    Reading through the last (closed) thread, I decided it would be fun to peg my CPU usage and see just how hot things would get. Take a look at this.

    I also tried playing back three H.264 videos from the Quicktime gallery at the same time, along with iTunes playing music with the visualizer active. CPU temps were in the mid 90s with the fans running ~5000 rpm. But then suddenly, Quicktime player unexpectedly quit. I am able to reproduce the problem. Is it possible this could be heat related, or something else? Any MBP owners up to running this little experiment? Or iMac, Mac Pro, Mini, MB owners for that matter?

    I have this issue. See sig for specs.

    Just ran CPU Test:
    cpu temp: topped at 97C
    gpu: topped at 82C
    finished tests: 60
    time: 8:35
    fan speed at top: 4100rpm

    cpu temp w/ fan @ 6000rpm: 85C

    What are the GPU temps in all these situations?

    EDIT: OP your fans should be capable of 6000RPM? Have you run SMC fan control?

    There's not enough information to make that statement.

    You're stating that you have reproduced the original poster's H.264 playback and iTunes test, resulting in a Quicktime crash while your CPU core temperature never went above 70C?

    I'll believe it when I see a picture.

    I'm closing this thread. And any other threads chem and eenu go back and forth on. The horse is dead. Stop beating it.

    And chem: any people you would have convinced have been convinced. Please try to find another crusade.
