Bug Description
This seems to be a problem on a number of Fujitsu Siemens Amilo models and also on other distros, so it's not Ubuntu specific. At least M3438G (which I have) M4438, 7440G, M1439G and probably more[1].
It was discussed on the kernel bugzilla[2] but was finally rejected as not an ACPI bug.
However, several of these models also carry a Linux-based media system called PowerCinema InstantOn, which has a working fan that adjusts after temperature. The company has a lot of source code available under GPL and similar on their homepage[3], but noone seems to know if there is a solution there.
I don't really expect any solution to this in the short term, but it is something that should be fixed sooner or later for proper laptop support - having it go full speed at all times affect both battery life, sound levels and the overall lifetime of the fan/computer.
