CPU Temperature in Ubuntu Linux

The temperature of the CPU/GPU depends upon the applications or programs that run in its system. If your device’s compatibility is not high, then your system may face an overheating issue. This system overheating issue occurs when the system’s temperature exceeds a specific limit.

CPU Temperature in Ubuntu Linux 1

System overheating creates a performance-related problem while working on the laptop/computer. Hence, CPU temperature monitoring can help you overcome the overheating issue by closing unnecessary system applications. This article covers the complete information on how to check CPU temperature in Ubuntu Linux.

How to Check CPU Temperature in Ubuntu Linux?

You can install sensors in the system to check CPU temperature in Ubuntu Linux. For this, open the command terminal and execute the following command in it:

$ sudo apt-get install lm-sensors

In case the system doesn’t have sensors installed, these sensors will start downloading after the successful execution of the above command.

You can also execute the watch -n2 sensors command to display the temperature-related details continuously.

Use Psensor to Check CPU Temperature in Ubuntu Linux

It is required to configure lm-sensors before installing Psensor in the system. lm-sensors is a hardware monitoring’s command-line utility, and you can also install hddtemp for measuring hard disk temperature.

Open the Linux terminal and execute the command below for installing lm-sensors and hddtemp:

sudo apt install lm-sensors hddtemp

After executing the above command, use the detection command to detect the hardware sensors:

sudo sensors-detect

Use the Sensors command to make sure that it is working correctly:


Once you execute the sensor command, you will receive a result like this:

Adapter: Virtual device
temp1: +43.0°C (crit = +98.0°C)
Adapter: ISA adapter
Physical id 0: +44.0°C (high = +100.0°C, crit = +100.0°C)
Core 0: +41.0°C (high = +100.0°C, crit = +100.0°C)
Core 1: +40.0°C (high = +100.0°C, crit = +100.0°C)

Now run the following command for installing Psensor in the system:

sudo apt install psensor

After installing Psensor in the system, run this application and configure it according to your requirements.
