Is 80 Degrees Celsius Hot for a CPU?

Are you concerned that your CPU may be running too hot? It’s a reasonable concern; high temperatures could cause damage to the computer processor, leading to costly repairs or even total replacement. So how hot is too hot for a CPU?

The quick answer is 80 degrees Celsius and above is too hot for a CPU!

But the more accurate response would depend on your specific operating conditions and hardware components. Let’s dive deeper into this topic of workflow background information and discover just how hot a CPU can truly get before needing some professional cooling attention!

Note: An overheated device could also mean that it has been hacked and infected with malware that is running in the background without the user's knowledge. These would increase your device's temperature and could even harm its components.

Concept of Heating

Electricity naturally produces heat as a byproduct. Heat transfer occurs when an object uses energy to start an action, such as a car engine or even our own bodies. Depending on the activity, different levels of electrical input may be required.

The same concept applies to our computer systems.

The Central Processing Unit (CPU) and other parts of your computer give off heat rapidly due to electricity flowing through circuits and meeting resistance.

Normal system maintenance, editing, and encoding can all place a load on your CPU, as can playing games, watching films, ripping, burning, and sharing files. It is possible to overheat when many tasks are going on.

CPU Temperature Thumb Rule

No two CPUs are the same, and their individual maximum temperatures are driven by a mix of specs, process architecture, and other elements. Nevertheless, there’s an overarching set of guidelines that apply to all processors – so as a rule of thumb, you can use these for guidance.

#1. Under 60°C or 140°F

A device that is under 60°C or 140°F temperature is safe. Operating at this temperature is a standard occurrence for your CPU, and it is normal for the device’s fan to not even be running.

#2. 60-70°C or 140-158°F

A device that is operating between 60°C and 70°C or 140-158°F temperature should be monitored, as it may indicate a potential problem. This is the range where you should consider taking steps to cool down your device if the fan is not running.

Common causes for the temperature rise could be too many tasks running in the background or dust collection in your CPU fan.

#3. 70-80°C or 158-176°F

A device that is operating between 70°C and 80°C or 158-176°F temperature should be taken seriously. Unless you’re pushing an overclock, you probably don’t want your device to run this hot. The processor may be starting to overheat at this point, and you should take proactive steps to reduce the temperature.

Common causes for the temperature rise could be that your fan has failed or the cooling system may not be adequate for the applications you are running on the system.

#4. Above 80-90°C or 176-194°F

A device that is operating above 80-90°C or 176-194°F temperature should be considered at risk, and you should take immediate action to cool it down. The processor is most likely overheating, and the system may suffer permanent damage if temperatures remain this high.

Common causes for the temperature rise could be device and program compatibility, as well as an internal problem that requires immediate attention.

#5. Above 90°C or 194°F

A device that is operating above 90°C or 194°F temperature should be considered dangerous, and you should take immediate action to power off the system. The processor is at imminent risk of failure, and the system may suffer permanent damage if temperatures remain this high.

Note: Certain processors are designed to perform fine with high temperatures of up to 85°C or 185°F, to ensure your PC is up to spec, it’s best practice to always consult the official website of its manufacturer.

How to Identify PC Overheating

You can find several methods for determining the temperature of your CPU. There are sensors built into some CPUs that may be accessed and viewed in the system’s firmware (BIOS or UEFI). To monitor your CPU temperature in real-time instead, you can install third-party software.

#1. BIOS/UEFI to Check CPU Temperature

To determine your CPU temperature accurately, you should utilize the basic input-output system (BIOS) or Unified Extensible Firmware Interface (UEFI) software. These systems ensure that the hardware of a device operates properly and efficiently.

Following are the steps to enter the system:

  1. To access your Settings, simply find the Taskbar and click on it.Windows 10 settings options
  2. Under Windows Settings, choose Update & Security.update settings BIOS
  3. On the side panel, you will find Recovery.
  4. Move your cursor to Advanced Startup and click on Restart Now.recovery and restart option
  5. On the reboot screen, find Troubleshoot and click it.choose an option bios
  6. Select the Advanced options settings.troubleshoot bios
  7. If your system uses BIOS, you can pass over this step – otherwise, select UEFI Firmware Settings.advance options bios
  8. To proceed, simply click Restart to confirm.restart bios

After you power on your computer, you will be brought to a page with its CPU temperature displayed. Though it’s just the one-time temperature, this should give an indication of how well your system is running.

#2. Third-Party Software

You can choose among user-friendly temperature-measuring third-party programs that are accessible for download if the method above seems too difficult or if you need to measure more than just the system’s temperature. Most of these third-party programs are free and simple to use. A few recommendations are:

  • HWMonitor
  • SpeedFan
  • Core Temp
  • HWInfo
  • Ryzen Master
  • Open Hardware Monitor

Maintain a Safe CPU Temperature

Although heating has an impact on performance, your PC’s temperature rarely rises to the point where it interferes with normal operation. However, if your computer is slow or frequently freezes, that is a strong indication that you are operating your CPU above the maximum temperature that is advised.

It is important to take preventive steps to avoid damaging your hardware and ensure optimal performance. A few recommended measures you can take at home are:

  • Keep a watch on your CPU’s temperature and check if it is running too hot or not.
  • Make sure that enough air is circulating inside the PC’s cabinet, or remove dust if needed.
  • Enable a fan speed control system to ensure that your CPU’s temperature is kept low.
  • Upgrade your cooling system if the temperature is above the maximum limit.
  • Keep an additional cooling system in place if you overclock your CPU often.
  • Keep the CPU tasks at a minimum and close down any background programs that are not needed.
  • Regularly run a malware scan to keep your PC virus free.
  • Avoid running intense applications for long periods of time.


Keeping your CPU temperature at an optimal level is essential for a healthy and efficient device. With the right tools, such as those mentioned above, you can easily monitor your system’s performance and take preventive measures to keep it running smoothly. Remember that temperatures over 80-90°C or 176-194°F should be considered dangerous and require immediate action to power off the system in order to avoid permanent damage. By following these tips, you will ensure that your computer runs optimally while avoiding any potential overheating issues.

What is Tjunction?

Tjunction is a parameter used in the thermal design of processors, which defines the maximum temperature at which a processor can be operated before damage occurs. It is also referred to as Tcase or Thermal Junction.

What is the difference between Tcase and Tjunction?

Tcase is the maximum ambient temperature at which a processor can be operated without damage, while Tjunction is the highest temperature that the on-die junction temperature can reach before damage occurs. The Tcase is usually lower than the Tjunction.

How to check if the system cooling solution is adequate?

You can use third-party software to monitor your CPU temperature in real-time and check if the cooling solution is adequate or not.
