4 Useful Tools to Monitor CPU and GPU Temperature in Ubuntu

Ubuntu is one of the most popular and widely used Linux distributions. It is known for its simplicity, reliability, and performance. However, like any other operating system, Ubuntu is not immune to overheating issues. Overheating can lead to a number of problems, such as decreased performance, system crashes, and even hardware damage. Therefore, it is important to monitor the temperature of your CPU and GPU regularly to prevent such issues from occurring.

lm-sensors

lm-sensors is a command-line tool that allows you to monitor temperature, voltage, and fan speed of your CPU, GPU, and other system components. It is a powerful tool that can provide detailed information about your system's hardware.

To install lm-sensors, open terminal and run:

sudo apt-get install lm-sensors

Once installed, detect sensors on your system with:

sudo sensors-detect

Follow the on-screen instructions to configure lm-sensors for your system. After the configuration process is complete, display temperature readings using:

sensors

The output will show detailed temperature information for all detected sensors:

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +42.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +42.0°C  (high = +100.0°C, crit = +100.0°C)

Psensor

Psensor is a graphical tool that displays temperature readings of your CPU, GPU, and other system components in real-time. It provides a user-friendly interface without requiring command-line interaction.

To install Psensor:

sudo apt-get install psensor

Once installed, launch Psensor from the Applications menu. Psensor displays temperature readings in the system tray and provides graphical charts for temperature monitoring over time. You can also configure temperature alerts to notify you when critical thresholds are reached, helping prevent overheating issues.

GNOME System Monitor

GNOME System Monitor is a graphical tool that provides detailed information about processes running on your system. It also displays CPU usage and basic temperature information in real-time.

To launch GNOME System Monitor, open the Activities menu and search for "System Monitor". Click on the Resources tab to view CPU usage graphs and basic temperature readings. While not as detailed as dedicated temperature monitoring tools, it provides a quick overview of system performance and thermal status.

Conky

Conky is a lightweight system monitor that displays system information directly on your desktop. It can show CPU and GPU temperatures along with other system metrics and is highly customizable.

To install Conky:

sudo apt-get install conky-all

Launch Conky by typing conky in the terminal. Conky displays system information on the desktop in real-time. You can customize its appearance and displayed information by editing the configuration file located at ~/.conkyrc. This tool is ideal for users who want persistent temperature monitoring visible on their desktop.

Additional Tools

Hardinfo

Hardinfo is a comprehensive system information and benchmarking tool that includes temperature monitoring capabilities.

sudo apt-get install hardinfo

After installation, launch Hardinfo and click on the "Sensors" tab to view CPU and GPU temperature readings along with other hardware information.

NVIDIA System Settings

For systems with NVIDIA graphics cards, nvidia-settings provides dedicated GPU temperature monitoring and performance data.

sudo apt-get install nvidia-settings

Launch nvidia-settings from the applications menu and navigate to the "GPU 0" section to view detailed GPU temperature and performance metrics.

Tool Comparison

Conclusion

Monitoring CPU and GPU temperatures is essential for maintaining system stability and preventing hardware damage. The tools covered lm-sensors, Psensor, GNOME System Monitor, and Conky each offer different approaches to temperature monitoring. Choose the tool that best fits your technical level and monitoring needs to keep your Ubuntu system running cool and efficiently.
