Hi Florian,

With release 0.11 of ibm-acpi you cannot control the fan speed of T4x or
R5x thinkpads.
You can only turn on/off the fan.

>From the README file you can read:

On the X31 and X40 (and ONLY on those models), the fan speed can be
controlled to a certain degree. Once the fan is running, it can be
forced to run faster or slower with the following command:

        echo 'speed <speed>' > /proc/acpi/ibm/thermal
