So you wouldn't recommend its usage? But then, how can I influence
the fan's behaviour? Should I load ibm_acpi that is not loaded by
default? You see, I'm not very familiar with this. To be honest, the
information provided by the ThinkWiki is surely helpful but also
confusing because there are so many ways to solve a problem. I know
http://www.thinkwiki.org/wiki/ACPI_fan_control_script but I don't
know which solution to choose.

I take your answer as an indication that fan control should work
out-of-the-box without user interference. What can I do---as a
common user, I'm not a programmer---to improve the situation?
