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)ДЄt 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. I've heard the fans at full speed and they should be there more often when it is required.This functionality depends on both your hardware and software. I know some people complain of noisy fans etc, this is not the same thing. This will ONLY be useful for your company AND your community. The motherboard control of fan speed is TOO CLUNKY and is making computers too hot. Just an allowance on choosing the parameter.

Please have one of your software engineers create a bios update that allows this ability immediately, within one week.ДЄgain - WITH DELL APPROVED SPECS, so the fan speeds wont be overclocked or underclocked. Otherwise you will be replacing more units.

It waits too long to cool down, Or doesn't even go into full fan speed!! You are shooting yourself in the foot Dell. My laptop is getting too hot, it is absolute NONSENSE to restrict this ability. I specifically need to increase my fan speed EARLIER (not exceeding dell specs) so that the computer will stay cool. Can be a simple control utilizing Dell approved specs. There NEEDS to be a utility or BIOS update to ALLOW Fan control on Dell xps 15, at the very least to Allow it to go into high performance fan speeds EARLIER.
