The solution to your issues is probably in the i8kutil package. i8k is support for many of the features dell puts into their inspiron and lattitude models. Do a google search and you should find more than enough info about it. I run the gkrellm plugin since that gives you a very nice overview over fan speed and also allows you to easily change the levels that trigger fan speed changes. Peter.
