4 Useful Tools to Monitor CPU and GPU Temperature in Ubuntu

4 Useful Tools to Monitor CPU and GPU Temperature in Ubuntu

The CPU or GPU temperature depends entirely on the usage of running programs or applications. Sensitive computer components such as CPUs have a finite lifespan and running them at a temperature that exceeds a certain limit (or at higher temperatures generally) can shorten it. Besides, it can also cause thermal throttling especially when the fan is not providing adequate cooling.

So it is important to monitor your system’s CPU temperature to avoid damaging it as a result of overheating. 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.

1. Glances

Glances is a cross-platform, advanced and popular real-time system monitoring tool that uses the psutil library to gather information from various system resources.

It can display information from sensors using the psutil and/or hddtemp tools. One of its intriguing features is the webserver mode which allows you to access it via a web browser to remotely monitor your Linux server.

There are various methods to install Glances on your system, but the preferred way of installing glances is using an auto-install script, which will install the latest production-ready version.

To install Glances on your system, use curl or wget command as shown.

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

How to Find the CPU Temp With An App: Core Temp

If you are looking for a fast way to check your CPU temp, it can be done quickly by downloading apps. There are apps to check CPU temp on both Windows and Mac devices. One of the most accessible ways to monitor the temperature of all your computer’s processors is with the Core Temp app.

Follow these steps to check CPU temperature with Core Temp:

Step 1: Open the application from your desktop.

Step 2: Locate the temperatures of your processors at the bottom of the widget.

Step 3: Maneuver to the bottom of your taskbar and select “show hidden icons” to quickly access core temps.

If you are looking to check CPU temp for macOS then you can download the Fanny Widget that allows you to monitor your fans and CPU temp right from your menu bar. For more control, you can even download SpeedFan, which allows you to manually control the speeds of your fans. For gamers and those wishing to access more information, you can download HWMonitor for a more detailed layout.

Download MSI Afterburner

MSI Afterburner isn’t the only software in the market that allows you to keep an eye on your internals, but it’s one of the easier ones to use, and it offers a great range selections.

Head over the bottom of MSI Afterburner’s official page or simply download it here. MSI Afterburner comes bundled with the RivaTuner Statistics Server (RTSS), which is actually what you need to have an in-game overlay with various statistics regarding your system.

While setting up MSI Afterburner, make sure to tick the box that reads “RivaTuner Statistics Server” when you’re prompted with which programs you’d like to install. The installer will set up both programs after you click next, and RTSS will always launch alongside MSI Afterburner every time you run the program. It won’t appear on your screen, however, and you’ll need to open it through its icon, which will be located on the bottom right corner of your screen.

Launch MSI Afterburner and start configuring your settings

When you first open MSI, you’ll be greeted with a small screen that looks like a car dashboard. You can find the clock speeds of your GPU on this panel in addition to its temperature. Click on the settings icon, a grey-black cog symbol placed toward the middle part of the window.

Once inside, head over to the monitoring tab, next to the “Fan” option on the top panel. There’ll be a ton of options in the monitoring tab. Make sure you’re going through the options listed below “Active hardware monitoring graphs” since CPU usage will be listed below this category alongside other useful statistics.

Put a checkmark on CPU Usage and all the other stats you want to track. While you’re doing that, click on each of them to turn on “Show in On-Screen Display” for each individual stat. This will make sure you’ll be able to see them live while you’re playing games and as they get recorded in the back.

If you’d like to turn on or off the on-screen display by command, not to occupy precious screen real estate, head over to the “On-Screen Display” tab, which is located next to the Monitoring section, and set yourself a hotkey to toggle on and off the on-screen display.

Go over the Rivatuner Statistics Server settings

Now that you’ve set everything you need on MSI Afterburner’s panel, you’ll need to make some finer adjustments on RTSS’ interface, which’s the program responsible for the in-game overlay you’ll be seeing.

Click on the RTSS icon located at the right bottom left of your screen. If you can’t see it there, click on the arrow pointing up to reveal more programs running in the background.

Once you open RTSS, make sure you have “Show On-Screen Display” and “On-Screen Display Support” turned on. You can easily make further customizations through here like your overlay’s size and where on the screen you would like to see it. We also recommend turning on the Stealth mode since there are a handful of games that don’t allow on-screen overlays even if their goal is to track your PC’s statistics. The Stealth mode makes sure RTSS stays under the radar.

Launch the game of your choice

If you’ve successfully followed all the steps so far there should be an in-game overlay on your screen when you launch the game of your choice. You can customize your overlay while your game is on, so we recommend going into the practice mode to make sure your overlay doesn’t block a part of your screen that could be essential during a match.

How to Monitor Your CPU’s Temperature

Checking your CPU temperature is as easy as firing up a monitoring program and using it to read out the value. Examples of these programs are HWMonitor, Core Temp, or NZXT’s CAM. These three are just a few examples of many, and for the purpose of this how-to we’ll show you how NZXT’s CAM and Core Temp work because we have found that these two are the easiest to use for casual purposes.

CAM is developed by PC case, power supply and CPU cooler manufacturer NZXT. While it’s intended to be used with their product, it works really well as a casual monitoring tool even if you don’t own any NZXT hardware.

Once installed, CAM offers a well-presented user interface (UI). The first block features the CPU’s status, which shows the load, temperature, clock speed and cooler fan speed. You can click on this block to access further details, as shown in the image below.

As you can see, the current temperature of this system’s CPU is 41 degrees Celsius, which is a healthy idle temperature.

CAM also has an overlay, which automatically turns on when you enter a game when CAM is running. This overlay can show you your CPU’s status while in-game, providing you with load temperature measurements.

You can also use the Core Temp tool to monitor the temperatures, which is a simpler tool that works with a more basic UI. Just be sure to untick the freeware in the installation menu first.

(Image credit: Core Temp)

As you can see, this CPU has been running at a temperature of 46 degrees Celsius and a maximum of 75 degrees Celsius (167 degrees Fahrenheit) and is, therefore, running at a normal temperature. The stress test temperature was achieved by running Prime95 for about 30 minutes, though the CPU hit its maximum temperature of 75 degrees Celsius within 10 minutes.

With Core Temp, the best way to monitor your temperature while gaming is to just have a good session, and then check back in with the program to see what the maximum recorded temperature is. Again, if this figure is at or beyond 95 degrees, you should be concerned. Anything between 80 and 95 degrees may have room for improvement.

The following table lists the test results when the monitor is in an Up state.

Test ResultDescription
UsageThe CPU load currently on the system represented as a percentage (%).
Usage-avgThe average CPU load on the system represented as a percentage (%). This result is based on the tests performed during the length of time specified in the Sample Size field.

Developed by network and systems engineers who know what it takes to manage today’s dynamic IT environments, SolarWinds has a deep connection to the IT community.

The result? IT management products that are effective, accessible, and easy to use.
