@Kern Sibbald: yes my answers are a bit inconsistent. But this "bug" does not affect my Dell Studio 17 with i7.
But in my case, the fan runs under ubuntu not so often than in windows 7. And I think that is because, ubuntu produces less load than windows. (cpu in idle) . And under both OS the fan seems to be controled, when I stress the cpu the fan runs higher and louder, but after that the fan calm down again.
