How to check the temperature of your PC (CPU, GPU, etc.)?

Keep an eye on the temperature of your computer is essential for maintaining good health. Especially since the internal components of a PC are particularly sensitive to temperature variations. Too much temperature can cause all sorts of problems : error messages, computer turning off or restarting spontaneously, slowdowns, etc.

For avoid overheatingso it is very important to monitor the temperature of your PC from time to time. Especially if you have a laptop. But strangely, the operating system Windows offers no way to check your computer’s temperature. You can go into your system’s BIOS to find the information from the on-board motherboard probes, however, this is not the most practical solution. The best is to use specialized software.

There are several free software programs that allow you to easily view the temperatures of your PC’s components. You have for example the excellent HWMonitor or the essential Speccy.

As I just told you, the easiest and fastest way to check your PC temperature is to use specialized software. To write this article, I decided to use HWMonitor.

Check component temperature

Once launched, HWMonitor displays all the temperatures of the internal components of your PC (motherboard, CPU, graphics card, SSD and hard drives). To see more clearly, do not hesitate to reduce all the parameters other than ” Temperature “.

Monitor fans

HWMonitor also allows you to monitor fan rotation speeds. If your PC is getting hot, your PC’s fans will have an overload of activity. To check your fans, open the ” fans then compare the current value to the minimum and maximum values. If the current rotation speed exceeds the maximum value, your fans may be clogged. In this case, do not hesitate to open the case of your PC to dust off the fans.

High CPU Temperature: When to Worry?

The maximum supported temperature varies from processor to processor. If you want to know the maximum temperature supported by your processor, you must consult its data sheet on Intel’s website Where from AMD. For my part, I have an Intel Core i7-8700k which is able to withstand a maximum temperature of 100°C. So obviously, the goal is not to approach this maximum value, because your CPU will quickly let you go. You just need to know that at this temperature, your processor will shut down on its own to avoid any damage.

Typically, your PC’s CPU is at risk when:

  • Below 60°C : no risk, everything is fine 😉
  • 60°C to 70°C : nothing to worry about, but remember to clean the dust from the fans all the same.
  • 70°C to 80°C : It’s getting hot there! If you haven’t overclocked your PC’s CPU, make sure the fans are working well and there’s no dust obstructing the airflow.
  • 80°C to 90°C : there, it is much too hot for long-term comfort. Check your hardware for faulty fans or dust, and if you’ve overclocked your CPU, remember to check your settings, especially the voltage if you’ve changed it.
  • Over 90°C : Flee to avoid the explosion! More seriously, turn everything off and very quickly! At this temperature your PC is at great risk.

To bring down the temperature of your PC, there are a few simple steps you can take. The first is to make sure your computer is well ventilated. To do this, make sure that there are plenty of open spaces around your computer and that the fans are working properly.

In addition, you can also blow out the dust that has settled in your case and on the fan blades using a dry air bomb.

Finally, you can also install a more efficient water-cooling type cooling system.
