1. Install the thinkfan software and the sensors: sudo apt-get install thinkfan lm-sensors 2. Make sure that the daemon controls the fan by editting the thinkpad.conf file: sudo nano /etc/modprobe.d/thinkfan.conf *by adding the following line: options thinkpad_acpi fan_control=1 3. Make the daemon load automatically at start-up by editting the file: sudo nano /etc/default/thinkfan *making sure that the START key is set to yes, i.e. there should be a line that says: START=yes 4. Detect your laptop's sensors: sudo sensors-detect *and just choose the default answers whenever you're prompted by hitting Enter. 5. Load the new modules. From ubuntu 13.10 this done by: sudo service kmod start *while for previous versions like 13.04 you instead will need to do: sudo service module-init-tools start 6. Figure out which sensors are in use: sensors *(the ones that indicate 0 degrees are not in use, I don't know why those are "detected" too). Remember which ones are in use. 7. Find out the full paths of these sensors: find /sys/devices -type f -name "temp*_input" *The output should be a list of paths like /sys/devices/... 8. Copy-paste the paths to the sensors into the configuration file /etc/thinkpad.conf. To do this, first open up the file: sudo nano /etc/thinkfan.conf *There should already be a line like #sensor /proc/acpi/ibm/thermal (0, 10, 15, 2, 10, 5, 0, 3, 0, 3) (the #-symbol means that that line is commented out). Add a line starting with sensor (without the #-symbol) and copy-paste you first sensor. Repeat this if you have more than one sensor. For example, on my machine, the output in step 7 yields /sys/devices/virtual/hwmon/hwmon0/temp1_input /sys/devices/platform/thinkpad_hwmon/temp3_input /sys/devices/platform/thinkpad_hwmon/temp4_input /sys/devices/platform/thinkpad_hwmon/temp5_input /sys/devices/platform/thinkpad_hwmon/temp6_input /sys/devices/platform/thinkpad_hwmon/temp7_input /sys/devices/platform/thinkpad_hwmon/temp1_input /sys/devices/platform/thinkpad_hwmon/temp8_input /sys/devices/platform/thinkpad_hwmon/temp2_input /sys/devices/platform/coretemp.0/temp4_input /sys/devices/platform/coretemp.0/temp2_input *The ones that are in use in my machine are the ones in the first and the last two lines, so I added the three lines: sensor /sys/devices/virtual/hwmon/hwmon0/temp1_input sensor /sys/devices/platform/coretemp.0/temp4_input sensor /sys/devices/platform/coretemp.0/temp2_input 9. Finally we can set the fan speed levels in the configuration file. Open the /etc/thinkpad.conf file if it wasn't open already. sudo nano /etc/thinkfan.conf *The fan levels I use on my ThinkPad x201 are: (0, 0, 51) (1, 50, 52) (2, 51, 55) (3, 54, 58) (4, 56, 63) (5, 60, 70) (6, 66, 79) (7, 74, 92) (127, 85, 32767) *The last line ensures full fan speed (127 = "disengaged" i.e. unregulated). You can fiddle with these levels to fit your needs/wishes, but PLEASE BE CAREFUL! 10. Reboot. Everything should work now. In order to check whether thinkpad is runnning correctly, use: sudo thinkfan -n *which starts thinkfan in verbose mode. You might want to stop the thinkfan daemon first: sudo /etc/init.d/thinkfan stop *If you want to start the thinkfan daemon again, type: sudo /etc/init.d/thinkfan start **Just to be complete, my /etc/thinkfan.conf configuration file is:

# IMPORTANT: # # To keep your HD from overheating, you have to specify a correction value for # the sensor that has the HD's temperature. You need to do this because # thinkfan uses only the highest temperature it can find in the system, and # that'll most likely never be your HD, as most HDs are already out of spec # when they reach 55 °C. # Correction values are applied from left to right in the same order as the # temperatures are read from the file. # # For example: # sensor /proc/acpi/ibm/thermal (0, 0, 10) # will add a fixed value of 10 °C the 3rd value read from that file. Check out # http://www.thinkwiki.org/wiki/Thermal_Sensors to find out how much you may # want to add to certain temperatures. # Syntax: # (LEVEL, LOW, HIGH) # LEVEL is the fan level to use (0-7 with thinkpad_acpi) # LOW is the temperature at which to step down to the previous level # HIGH is the temperature at which to step up to the next level # All numbers are integers. # # I use this on my T61p: #sensor /proc/acpi/ibm/thermal (0, 10, 15, 2, 10, 5, 0, 3, 0, 3) #(0, 0, 55) #(1, 48, 60) #(2, 50, 61) #(3, 52, 63) #(4, 56, 65) #(5, 59, 66) #(7, 63, 32767) # My settings for my ThinkPad X201: (kris) sensor /sys/devices/virtual/hwmon/hwmon0/temp1_input sensor /sys/devices/platform/coretemp.0/temp4_input sensor /sys/devices/platform/coretemp.0/temp2_input (0, 0, 51) (1, 50, 52) (2, 51, 55) (3, 54, 58) (4, 56, 63) (5, 60, 70) (6, 66, 79) (7, 74, 92) (127, 85, 32767) *Good Luck*
