8 best CPU temperature monitors in 2020 – (and GPU monitors)

the best CPU temp monitors
In summer (but not only), keep in mind that extremely high temperatures will definitely affect the performance of your laptop or PC. However, don’t worry because this article is all about the best CPU temperature monitors. The first CPU temperature monitor was invented by an unsung hero to prevent excessive heat from damaging essential components of your own PC.

This type of app constantly monitors the temperature not only for your CPU but also for your GPU, HDD / SSD, motherboard, etc. by checking their sensors including temperature, voltage and fan speed and providing instant information regarding the general System health.

A CPU temperature monitor is extremely important if you’re not lucky enough to own a high-tech water-cooling case. So if you enjoy gaming, make sure your system isn’t suffering from excessive heat. And CPU temperature monitors are the only way to achieve that. Additionally, the best CPU temperature gives you options to solve at least some of the critical “heat related” problems of your system by allowing you to change various parameters like the speed of your CPU / GPU fan to reduce the overheating output as quickly as possible.

Also, if you’re looking to overclock, knowing how to choose a good tool to monitor system temperature is a crucial detail, assuming you plan to stay in that racket for a long time. By the way, read this article if you want to make sure your current cooling solution doesn’t disappoint on the hottest days of this summer. We will thank you later.

To make it really easy for our users, the best CPU temperature monitor allows you to set your CPU speed, view the current CPU internal voltage, monitor the temperature on all cores, view the GPU temperature and allow it to happen when you have the minimum / want to adjust the maximum speed of the CPU, you can automatically shut down the system if it overheats and finally offer a portable solution just in case.

Now, after a brief commercial break, let’s take a look at some of the best CPU temperature monitors on the market today.

8 best CPU temperature monitors


The best CPU temperature monitor for Windows only

We start with HWMonitor, a classic hardware monitor software that not only measures your CPU temperature but also the PC’s most important integrity sensors, i.e. H. GPU temperature, voltages and fans. In this regard, HWMonitor is relatively advanced, and the latest update can handle the vast majority of sensor chips, including the ITE® IT87 series, most Winbond® ICs, and more.

The same applies to on-die heat sensors on modern CPUs, HDD / SSD temperatures via SMART and of course GPU temperatures. There are two versions of the software to choose from: the Freebie and the extended PRO version. However, both are well designed and easy to use with a focus on simplicity and minimalism.

Since HWMonitor can record (and log) all of your hardware metrics in real time, it gives you an educated estimate of the overall health of your machine, which is useful in a variety of day-to-day scenarios – Daily maintenance of diagnostics, etc. The main difference between the free version and of the Pro version is that the latter enables remote monitoring for up to 20 connections, has an improved user interface and adds graphical generation. Remote monitoring means that you can monitor several computers in a list view and see the values ​​for value, min and max of the most important hardware components next to each PC.

However, if you need advanced features like a temperature warning alarm or fan speed control, you’ll have to look elsewhere.


  • Real-time monitoring of CPU, HDD, CPU and MoBo temperatures
  • Free version available. With the Pro version you can monitor multiple computers remotely
  • Very simple and intuitive user interface

  • Advanced functions are missing
  • Windows-only deal

Open the hardware monitor

The best CPU and GPU temp monitor for Linux operating systems

Open hardware monitor
Are you looking for an extremely simple and lightweight temperature monitoring solution? You just found it. Enter Open Hardware Monitor, an open source and absolutely free software developed by loads of lovely people to monitor everything that needs to be monitored on your computer: fan speeds, temperature sensors, CPU load, CPU voltages, and Clock rates.

Be warned: Just like the HWMonitor presented above, Open Hardware is just a kind of “silent partner” or, to put it very clearly, it’s a kind of “look but not touch” deal. So yeah, it’s free and cool and all, but there’s not much you can do other than monitor the situation since you can’t adjust the fan speed or change the voltages, you know, advanced stuff.

But hey, at least it’s free, isn’t it? Open Hardware supports all common software programs and is compatible with most Intel and AMD-based SoCs as well as ATI and Nvidia graphics cards. Hard drives and SSDS are read through SMART, of course, and the good news is you can run Open Hardware on both Linux and Windows computers, which is great.

Incidentally, no installation is required and, despite its simplicity, Open Hardware provides a very detailed report after the “system check” is complete.


  • Easy to use, free to download, no installation required
  • Monitors temperature, CPU frequency, CPU voltage, CPU load, RAM load, fan and GPU
  • Open source works on both Windows and Linux
  • Low cost / low expectations temperature control
  • Receives regular updates so don’t worry, open source is the best

The best temperature monitor for advanced users

aida64 extreme
After all of these giveaways and basic CPU temporary software, it’s finally time for the big guys to step in and reclaim their territory. Enter AIDA64 Extreme, a program designed for so-called “power users,” or in other words, geeks whose only job is to keep an eye on what’s going on with their expensive rig.

All jokes aside, AIDA64 Extreme will become your best friend if you’re into overclocking, heavy gaming, and those serious things as its premium features and hardware detection engine are pretty much the gold standard in the industry.

AIDA64 Extreme not only gives you accurate and detailed information about your hardware and software, it also provides support for overclocking and diagnostic functions. In addition, you get real-time monitoring of all of your computer’s sensors, including temperature, voltage and fan speed readings, while diagnostics detect and mitigate possible hardware problems.

If you want to evaluate a specific component of your rig, AIDA64 Extreme can perform stress tests for the entire system or individual components. The bad news is that AIDA 64 Extreme only works on Windows computers and costs money.


  • The professional hardware monitoring solution comes with a 30-day free trial
  • Support more than 250 kinds of sensors, clean and intuitive user interface
  • Support for external displays, software audits, benchmarking, stress tests and diagnostics
