There are apparently special issues w/r/t Thinkpad fans and Linux, ref
http://www.thinkwiki.org/wiki/How_to_control_fan_speed

If I understand correctly, there were problems with fan control on older
thinkpads, which led to fans being reset to run too fast, leading to
noise complaints about fans on some Ubuntu installations on T series
laptops.

On Ubuntu, there are some fan control packages associated with
Thinkpads. I found them with the following command:

apt-cache search thinkpad 

This is just from memory, as I'm a bit intense within RHEL 6 at the
moment.

Thanks,
