A computer that overheats too much can become slow, unstable, or even get damaged. In this guide, I show you how to monitor the CPU and GPU temperature with free and reliable tools, and how to lower it if necessary. A simple guide for non-expert users, but very effective.
Why it is important to check the PC temperature
When the computer overheats, problems start: sudden slowdowns, system freezes, automatic shutdowns. In extreme cases, the hardware can suffer permanent damage. Monitoring the temperature is therefore essential, especially in summer or if you use heavy programs.
What is the normal temperature for CPU and GPU?
Here is an indicative estimate of acceptable temperatures:
- CPU (at idle): 30–50°C
- CPU (under load): 60–85°C
- GPU (at idle): 35–55°C
- GPU (gaming/rendering): 70–90°C
If it goes over 90°C, it’s time to take action.
How to monitor the PC temperature (simple methods)
1. HWMonitor
A free and lightweight program. It shows real-time temperatures of CPU, GPU, SSD, motherboard.
2. Speccy
Another free tool that offers a clear overview of the PC components, including the temperature.
3. Manufacturer’s software
Many motherboard and laptop manufacturers offer integrated utilities for temperature control (e.g. MSI Dragon Center, ASUS Armoury Crate).
What to do if the PC is too hot
- ✅ Clean the fans and air vents from dust
- ✅ Use a cooling pad (for laptops)
- ✅ Keep the PC on hard surfaces, never on blankets or sofas
- ✅ Close heavy non-essential programs
- ✅ Replace the thermal paste (if you have a desktop)
Also check the BIOS/UEFI
If you don’t want to use software, you can check the CPU temperature by entering the BIOS/UEFI during startup. Usually, you access it by pressing F2 o DEL immediately after powering on.
Conclusion
Monitoring your PC’s temperature is simple but can save you from serious trouble. It only takes a few minutes to know if your system is healthy and, if necessary, take the right countermeasures. Start today: your computer will thank you.
