It’s important to measure the temperature of every single component of your computer so you don’t get too hot and know your computer’s limit. This is also especially crucial if you overclocking one of the computer components.
Not only that, a component that gets too hot too fast may be a sign that it needs to be cleaned or even replaced soon.
Here are 5 best free apps to monitor PC’s temperature!

#1 CrystalDiskInfo

CrystalDiskInfo not only comes with a simple interface but also offers advanced monitoring for almost all hardware inside your PC. It mainly keeps your eyes on the processor, graphics card, motherboard, and storage. When one of them gets very hot, the system will show a warning to prevent over-heat.
It has an AAM/APM control, graph chart, and S.M.A.R.T information which indeed helpful for monitoring PC health. CrystalDiskInfo able to send a notification email to someone when the machine’s temperature is about to break. It is literally useful for all-day operated computers, like servers or workstations.
#2 Core Temp

Core Temp is compact, lightweight software to monitor processor. It provides a real-time temperature of each core along with power consumption. When the temperature is normal, its icon in the task will glow gently in green, orange for warm, and red for hot. It seems not precise for gaming usage which generally on a full screen, and so blocking the taskbar.
Instead, the Core Temp may be suitable for a video editor or any professional software that consume more power during the work, like rendering video or 3D design. This app comes with a small size and occupies less memory; it’s good for the low-end computer.
#3 Open Hardware Monitor

Open Hardware Monitor is a free open source software that provides a real-time temperature of the chip, voltages load, speed clock, and fan rotation speed. That information outlined in a tree-like structure and help you easy to spot every single component inside the machine. The program is capable of running in the system tray to reduce the load. Monitor gadget also available for Windows 7 user.
It supports major chip architecture, as well as the motherboard, GPU, and storage. Unfortunately, this simple app did not show a warning once the temperature gets over, so it relying upon the user to check the temperature regularly.
#4 SpeedFan

SpeedFan is typically basic software to monitor vital signs of the computer, including HDD RPM, voltages, temperature, and some important events. To be honest, this app’s interface seems like an early 2000 computer, not surprising because the developer has launched the software about that time. It can detect any fans and gain control of them.
Despite have fewer features, the SpeedFan provides fan control where you can adjust the speed to lower hardware’s temperature. When the room temperature is cold, you can decrease the fan RPM or shut it down for saving energy. Meanwhile, if you are using a notebook that has no fan, this software might not be beneficial.
#5 HWiNFO

HWiNFO provides in-depth information regarding hardware’s health, not just temperature. It has tremendous descriptions that probably you don’t want to read all altogether. The interface is pretty much complex, but you can switch to a summary version if you wish. Generated report and alert can be exported to the text, CSV, XML, or HTML format.
This kind of software is good for the server, cryptocurrency miner, or anything else which requires an all-day workload. HWiNFO is available both the installer and a portable version for Windows and DOS.
Alright. That’s the best five software (in my opinion) to monitor a PC’s temperature, at least from the most simpler to the complex one. Don’t forget to regularly clean your PC from dust so the air can flow through smoothly and reducing the overall temperature.

Additional Insights: Enhancing Your PC’s Cooling Strategy
Why Monitoring Isn’t Enough
While monitoring your PC’s temperature is essential, it’s equally important to take proactive steps to maintain optimal cooling. Even the best software can only alert you to overheating—it’s up to you to address the root causes.
Simple Cooling Tips
- Improve Airflow: Ensure your PC case has unobstructed airflow. Use high-quality intake and exhaust fans to keep air circulating efficiently.
- Reapply Thermal Paste: Over time, thermal paste on your CPU and GPU can degrade. Reapplying a high-performance thermal paste can significantly improve heat transfer.
- Upgrade Cooling Solutions: Consider upgrading to an aftermarket air cooler or a liquid cooling system for better performance, especially if you’re overclocking.
Advanced Cooling Options
For gamers and professionals pushing their systems to the limit, investing in advanced cooling solutions like custom water-cooling loops or hybrid coolers can make a noticeable difference. These setups not only lower temperatures but also reduce noise levels.
FAQ
How often should I check my PC’s temperature?
It’s recommended to monitor your system during heavy workloads like gaming or video editing. Periodic checks during regular use can help identify potential issues early.
What’s the ideal temperature range for my CPU and GPU?
For most CPUs, staying below 80°C under load is safe. GPUs can handle slightly higher temperatures, typically up to 85°C. Always consult your hardware manufacturer for specific thresholds.
Can dust buildup affect my PC’s temperature?
Absolutely! Dust can clog fans and vents, restricting airflow and causing components to overheat. Regular cleaning with compressed air is crucial for maintaining optimal performance.
Should I invest in a liquid cooling system?
If you’re running a high-performance system or overclocking, liquid cooling can be a worthwhile investment. It offers superior cooling compared to air solutions and operates more quietly.
Are there mobile apps for monitoring PC temperatures?
Yes! Apps like NZXT CAM and HWiNFO offer mobile integration, allowing you to monitor your system remotely.
By combining reliable monitoring tools with effective cooling strategies, you can ensure your PC runs smoothly and efficiently for years to come.
