![]() Anything to do with sensors-detect and sensors it never discovers the fans, so fancontrol has no sensor to use.We've followed the entirety of the fan speed control page where it is relevant to Dell laptops, and completely exhausted all of the following: There is no clear option in the BIOS to change the fan settings, except for a very broad "performance" versus "power" selector which doesn't seem to hand control to userspace, ever. The BIOS still seems to trigger them, but on a highly irregular and unhelpful basis- we regularly get 90C temperatures under load. He has a Precision 7560, I have an XPS 15 9520, respectively with 11th gen and 12th gen i9 CPUs.įor some reason, neither of us are able to control our fans. Remember, maintaining an optimal temperature for your hardware can extend its lifespan and improve its performance.įor more information on lm-sensors and Fancontrol, you can check their official documentation at and Fancontrol GitHub page.A friend and I have been fighting with fan control on our Dell laptops for a few months now. If not, adjusting your BIOS settings or installing proprietary graphics drivers may provide a solution. You can do this by going to the “Additional Drivers” section in the Ubuntu System Settings.Ĭontrolling your fan speed in Ubuntu using lm-sensors and Fancontrol can be a straightforward process, provided your hardware supports PWM control. For example, if you have a Radeon 6850 card installed, you can install the proprietary graphics drivers for your card, which may include additional fan control options. Proprietary Graphics Drivers: Some graphics cards have their own fan control settings. ![]() Look for options related to fan control or fan speed and adjust them accordingly. BIOS Settings: Restart your computer and enter the BIOS menu (usually by pressing Del or F2 during startup).If you encounter the aforementioned error, there are a few alternatives you can try: However, if you receive an error message stating “There are no pwm-capable sensor modules installed”, your hardware may not support PWM (Pulse Width Modulation) control. This command will guide you through the process of testing and configuring fan speed control. Run the following command: sudo pwmconfig To configure Fancontrol, we need to create a configuration file. Similar to the lm-sensors installation command, this command tells apt-get to install the fancontrol package. Run the following command: sudo apt-get install fancontrol This command should display a list of your system’s sensors, along with their current readings. Once the detection is complete, verify that lm-sensors is working properly by running: sensors In most cases, the default answers (by pressing Enter) will be sufficient. This command will ask you a series of questions about your hardware. Run the following command: sudo sensors-detect Configuring lm-sensorsĪfter the installation is complete, we need to detect the sensors on your system. The install parameter tells apt-get what action to perform, and lm-sensors is the name of the package we want to install. This command uses the apt-get package manager to install lm-sensors. Open your terminal and run the following command: sudo apt-get install lm-sensors To get started, we need to install lm-sensors. It is highly customizable, allowing you to set your own thresholds and speeds. It provides a command-line interface to gather sensor readings, which can be used in conjunction with Fancontrol to manage your fan speed.įancontrol is a script that uses the lm-sensors tool to regulate fan speed according to system temperatures. Lm-sensors is a software tool that monitors the temperature of your system and the speed of your fan. Conclusion Introduction to lm-sensors and Fancontrol.Introduction to lm-sensors and Fancontrol.
