Comment 147 for bug 751689

@Philipp: With my "solution" which works for, there is no need to run the fan on disengaged. At the moment e.g. the fan is not running at all and I am happy with 44° Celsius which rather low. But when I am stressing the system more, the temperature hardly ever rises above 60° Celsius. Then the fan is running, but definitely not on full speed. Before that I was seldomly below 80° and I often had the system quickly rising towards 100°. Unfortunately I can not say what really did the trick. But I am quite sure the Bios can only contributed with a small factor. I updated the Bios months before the other things and there was only a little improvement. I rather suspect that installing the installing "i965-va-driver" and a newer kernel did something. I suspect this, because the overheating mostly only happened when I was doing things which stressed the gpu (watching movies, encoding video). At least in my installation the "i965-va-driver" was never installed by default.
