Tools to check PC Overheating

Anyone sitting in front of their computer in a non-air-conditioned room may also notice that their system suddenly has a little more trouble than usual with certain tasks. It all takes a little longer, the place is just a little more unstable and the fans make more noise than usual. It is suspected that it has to do with the heat. Just a pity that most built-in measuring software only takes care of a single component, and that you have to open separate windows to measure the temperature of the CPU, video card, motherboard and so on.

But luckily there are other ways to measure the heat build up in your cupboard.

Hardware Sensors Monitor

It is a simple website that the makers of Hardware Sensors Monitor (in short: Hmonitor) have. The shareware program (14 days on trial, and then put down at least $ 23) is, despite the enormous retro style of the website, very reasonably maintained. In addition to the temperature of the CPU and video card, Hmonitor also maintains voltage, so that before that lightning strikes the motherboard to its grandmother, you still have 0.0000000000000000000000000000000000000000000 (…) 1 second to respond. Hmonitor can also adjust the voltages and let the fans run faster.


SpeedFan is freeware, and therefore completely free. The program can, just like Hmonitor, adjust the fans as far as the hardware allows. A very useful function of SpeedFan is that it can also measure the temperature of hard disks by using SMART, also SCSI. You can even change the FSB with it (although the makers indicate that this should be considered as a ‘bonus’).Lm Sensors

The previous two tools are for Windows. This tool is not. Lm-Sensors is extremely modular in design and can be adjusted entirely to taste. What information do you want exactly? Which individual chips on your motherboard are important to you? It takes a little peeling, but then you also have something.

Temperature Monitor / HWMonitor

This tool for macOS may not be updated for a few years, it is still supported. Temperature Monitor / HWMonitor is a program that Apple is not a fan of. After 14 years of development, the group threw in the towel after Apple began to bother about access to certain system components.

The software can still be downloaded, but your mileage may vary.

CPUID / HWMonitor

You could view CPIUD’s HWMonitor as the Windows counterpart of the aforementioned macOS tool. This allows you to read out various sensors and thus discover the temperature, voltages and fan speed. With the free version you can already do a lot, but if you find it all too little, you can go for HWMonitor Pro. Core Temp

The fastest and easiest way to check your CPU temp is with the appropriate name Core Temp. Pay attention during installation! Like many free programs, it tries to install bloatware unless you uncheck some boxes during installation.

This tool also measures the temperature of your CPU and reads data from other sensors in your PC. If you want even more details, click on the Show hidden icons button in the notification area on the right side of the Windows taskbar. You see a temperature list for each individual CPU core.

In the Settings menu of Core Temp, you can adjust exactly what you see in the system tray and how you see it, but the standard configuration makes it very easy to see if your CPU is overheated or working as expected.


HWInfo is an in-depth system monitoring tool that gives many details about each component of your PC’s hardware. If you choose to run it in sensor-only mode, scroll to the CPU section – the special section, not the CPU temperature section of the motherboard – to reveal current temperatures and other detailed details.

NZXT cam

CAM is another popular option with a varied set of skills. The sleek interface is easier to read at a glance than that of most other monitoring tools, and the program displays all sorts of useful information about the CPU, graphics card, memory, and storage. Cam also includes an in-game FPS overlay and overclocking tools, in addition to other functions. You can use the mobile apps from NZXT Cam to keep an eye on your software when you are away from your PC.

Open Hardware Monitor

Open Hardware Monitor and SpeedFan are other well-known monitoring tools that can track system information. You have options! But to simply check the CPU temperatures of your computer, the simple focus of Core Temp cannot be beaten.
