How to monitor CPU and GPU temperature in Ubuntu Linux

Overheating of laptops is a common issue one faces these days. Monitoring hardware temperature may help you to diagnose why laptop is getting overheated.
In this article, we will share some useful command-line tools to help you keep a close eye on the temperature of your CPU and GPU.


Sensors is a simple command-line utility that displays the current readings of all sensor chips including the CPU. It comes pre-installed some Linux distributions such as Ubuntu by default, otherwise install it as shown.

$ sudo apt-get install lm-sensors

Then you can run the following command to detect all sensors on your system.

$ sudo sensors-detect

Example output:

$ sudo sensors-detect 
# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# System: Hewlett-Packard HP EliteBook Folio 9470m [A1029D1103] (laptop)
# Board: Hewlett-Packard 18DF
# Kernel: 5.3.0-28-generic x86_64
# Processor: Intel(R) Core(TM) i7-3687U CPU @ 2.10GHz (6/58/9)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): yes

Once detected, you can run the following command to check CPU temperature, GPU temperature, fan speed, voltage, etc.

$ sensors

Example Output:

$ sensors
Adapter: ISA adapter
Package id 0:  +57.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:        +56.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:        +57.0°C  (high = +87.0°C, crit = +105.0°C)

2. Glances

Glances is a cross-platform curses-based system monitoring tool written in Python. It uses the psutil library to retrieve information from your system.
It’s accommodating all in one place, It shows a maximum information in a minimal space through curses or a web-based interface.
The information dynamically adapts depending on the size of the user interface.
Glances is capable to monitor CPU usage, Memory usage, Swap usage, System Load Average, Process list, Network interface, Disk I/O, Raid, Sensors (CPU temperature), Battery, Filesystem Usage, Docker, Monitor, Alert, System info, Uptime, etc…
To install Glances on your system, use next command:

$ sudo apt install glances -y

Once you have installed it, start Glances and press f key to view sensors information.

$ glances

Example output:

Glances – Monitor CPU and GPU Temperature
Glances – Monitor CPU and GPU Temperature

3. i7z

The i7z is a tool that reports the Intel Core i7, i5 and i3 CPU information about Turbo boost, per CPU frequencies, multipliers, temperature as well as the times spent in the C-state in real time.
You can install it on your Ubuntu system by running the following command.

$ sudo apt install i7z -y

Once installed, run i7z with root privileges as shown.

$ sudo i7z

Example output:

Show Intel Core Information with Temperature
Show Intel Core Information with Temperature
