Since 12.04 my thinkpad (T60) regularly shuts down due to heat. I don’t like it and I am afraid of damage – to hard drives or to the system.

The problem is described in many places and many different fixes, remedies and work arounds exist. Most of them lack proper documentation, so I am reluctant to try them. Even thinkfan, which is quite popular, scares me more than it helps.

Here is a collection of relevant information I found:

  1. Bug report at launchpad
    https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689
  2. Show temperatures of all sensors
    cat /proc/acpi/ibm/thermal
  3. Show Speed of fan
    cat /proc/acpi/ibm/fan
  4. Thermal Sensors
    http://www.thinkwiki.org/wiki/Thermal_sensors
  5. List of ways to control fan speeds at Thinkwiki.org
    http://www.thinkwiki.org/wiki/How_to_control_fan_speed
  6. Thread at askubuntu

  7. Howto at NeoLocus

  8. Howto at thinkwiki.de [in German]:

For now I went with #7 (thinkfan howto by Neolocus), and I do hear a substantial difference in fan activity – but I am still scared.
