The first line of the sensors output is the chipset your motherboard uses to read the speeds/temps/voltages. If your fan speed is shown and higher than 0, skip the next step. If your output does not display an RPM for your CPU fan, and you are positive it is running, you need to increase the fan divisor. The fan can run so slowly and quietly, because it's a large 12 cm fan made by Zalman (it's the 7000B AlCu). The CPU temp is a little high, so I need to do some tweaking of the config there. Memory size (MB): 256Notice that my CPU fan is running really slowly, only 1100 RPM. 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.VCore: +1.54 V (min = +1.69 V, max = +1.86 V) 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.
