There are two primary methods to check your CPU temperature in Ubuntu:

1. Using the sensors command:

• Open your terminal.
• Type sudo apt install lm-sensors and press Enter to install the required tools.
• Enter your password when prompted.
• Once installed, run sudo sensors-detect and follow the on-screen instructions to configure your system's sensors.
• Finally, run sensors to view the CPU temperature.

2. Using a graphical interface:

• Install Psensor: sudo apt install psensor
• Launch Psensor from your applications menu.

Note:

• The exact output of the sensors command may vary depending on your system's hardware.
• If you're unsure about the normal temperature range for your CPU model, consult your system's manual or online resources.

Additional tips:

• If you need to monitor CPU temperature in real-time, you can use the watch command with the sensors command: watch sensors.
• For more advanced monitoring and customization, consider using tools like htop or conky.

By following these methods, you can easily check and monitor your CPU temperature in Ubuntu.
