Measuring CPU temperature on Ubuntu/Linux is an essential task for preventing overheating and improving system performance. There are several methods available, including GUI tools like Psensor and command-line tools like lm-sensors and sensors. In this blog post, we will explore different ways to measure CPU temperature on Ubuntu/Linux, along with some third-party apps and scripts.

Using Psensor

Psensor is a popular GUI tool for monitoring CPU temperature on Ubuntu/Linux. Users must first configure lm-sensors, a command-line tool that monitors hardware sensors, to use Psensor. We will provide a step-by-step guide to set up and use Psensor for monitoring CPU temperature.

To install Psensor, open the terminal and type the following command:

sudo apt-get install psensor 

After installing Psensor, you need to configure lm-sensors. To do this, type the following command in the terminal:

Follow the prompts and say yes to all the questions. After sensors-detect is done running, type the following command to update the sensors configuration:

Now you can start Psensor by searching for it in the applications menu. Once opened, you can see the CPU temperature in the main window.

Command-line tools

Command-line tools like lm-sensors and sensors are powerful tools to monitor CPU temperature on Ubuntu/Linux. We will explain how to install and use these tools to measure CPU temperature. The sensors command shows the most recent values from all sensor chips, including the CPU.

To install lm-sensors, open the terminal and type the following command:

sudo apt-get install lm-sensors 

After installing lm-sensors, you need to detect the sensors on your system by typing the following command:

Follow the prompts and say yes to all the questions. After sensors-detect is done running, type the following command to update the sensors configuration:

To check the CPU temperature, type the following command in the terminal:

This will display the CPU temperature along with other sensor information.

BIOS and /sys directory

Users can also check CPU temperature via BIOS or by using the /sys directory, a virtual file system for Linux kernel and hardware information. We will provide a walkthrough guide to accessing and using BIOS and /sys directory to measure CPU temperature.

To access the BIOS, restart your computer and press the key that appears on the screen to enter the BIOS setup. The key to enter the BIOS setup varies depending on your computer manufacturer.

To check the CPU temperature using the /sys directory, open the terminal and type the following command:

cat /sys/class/thermal/thermal_zone0/temp 

This will display the CPU temperature in Celsius.

Third-party apps and scripts

There are various third-party apps and scripts available to monitor CPU temperature on Linux. Glances is a cross-platform system monitoring tool that can monitor CPU and GPU temperature in Ubuntu. Hardinfo is another GUI tool that provides detailed hardware information, including CPU temperature. i7z is a command-line tool that provides per-core CPU temperature readings. We will explain how to install and use these tools to monitor CPU temperature.

To install Glances, open the terminal and type the following command:

sudo apt-get install glances 

To start Glances, type the following command in the terminal:

This will display the CPU temperature along with other system information.

To install Hardinfo, open the terminal and type the following command:

sudo apt-get install hardinfo 

To start Hardinfo, search for it in the applications menu. Once opened, you can see the CPU temperature in the Sensors tab.

To install i7z, open the terminal and type the following command:

To check the CPU temperature using i7z, type the following command in the terminal:

This will display the per-core CPU temperature readings.
