Add a line starting with sensor (without the #-symbol) and copy-paste you first sensor. (the #-symbol means that that line is commented out). There should already be a line like #sensor /proc/acpi/ibm/thermal (0, 10, 15, 2, 10, 5, 0, 3, 0, 3) To do this, first open up the file: sudo nano /etc/nf Copy-paste the paths to the sensors into the configuration file /etc/nf. The output should be a list of paths like /sys/devices/.

Find out the full paths of these sensors: find /sys/devices -type f -name "temp*_input" (the ones that indicate 0 degrees are not in use, I don't know why those are "detected" too). Figure out which sensors are in use: sensors While for previous versions like 13.04 you instead will need to do: sudo service module-init-tools start From ubuntu 13.10 this done by: sudo service kmod start Detect your laptop's sensors: sudo sensors-detectĪnd just choose the default answers whenever you're prompted by hitting Enter. there should be a line that says: START=yes Making sure that the START key is set to yes, i.e. Make the daemon load automatically at start-up by editting the file: sudo nano /etc/default/thinkfan Make sure that the daemon controls the fan by editting the nf file: sudo nano /etc/modprobe.d/nfīy adding the following line: options thinkpad_acpi fan_control=1

Install the thinkfan software and the sensors: sudo apt-get install thinkfan lm-sensors (which is basically a translated version of this German guide: The thinkfan software is available in the standard ubuntu software repositories, but it does require a few steps to configure. As the name obviously suggests, it is specifically made for ThinkPads ( thinkpad_acpi). If you own a ThinkPad, there's a piece of software called thinkfan that does exactly this. This man page gives some useful info on the settings and what they really do. (Controls hwmon0/device/fan2_input) INTERVAL=2Īnd on a different system it is: INTERVAL=10ĭEVPATH=hwmon1=devices/platform/coretemp.0 hwmon2=devices/platform/nct6775.2608 In my case /etc/fancontrol for CPU I used: This will also make the fancontrol service run automatically at system startup.

(In my case I set interval to 2 seconds.) Make adjustments to fine-tune /etc/fancontrol and use sudo service fancontrol restart to apply your changes.Run through the prompts and save the changes to the default location.

If you have just one fan, make sure to use a temperature sensor for your core to base the fancontrol speed on.

You will have to specify what sensors to use.

After script loops through all fans, you can configure which fan corresponds to which temperature. This script will stop each fan for 5 seconds to find out which fans can be controlled by which PWM handle. Note: If you're running Ubuntu 12.04 or lower, this 3rd step command should be replaced by sudo service module-init-tools restart Run sudo service kmod start This will read the changes you made to /etc/modules in step 2, and insert the new modules into the kernel. Type "yes" to have sensors-detect insert those modules into /etc/modules, or edit /etc/modules yourself. If you feel unsure, read the comments and try to search a web and get some high-level overview before YES-ing everything, maybe being selective with your YES-es will still be enough)Īt the end of sensors-detect, a list of modules that need to be loaded will be displayed. Saving all your work for eventual crashes/freezes/restarts before handling system configuration is always good idea. There is no guarantee that this process will not damage your system permanently, I just think that chance of such critical failure is really really low. (Potentially, this can damage your system or cause system crash. In terminal type sudo sensors-detect and answer YES to all YES/no questions. Install the lm-sensors and fancontrol packages.

If it does, but the software (aka kernel) doesn't know how to control it, you are without luck. If your hardware doesn't support fan speed controls, or doesn't show them to the OS, it is very likely that you could not use this solution. This functionality depends on both your hardware and software.
