Is 80 Degrees Celsius Hot for a CPU? Is It Bad?

Share on:

The CPU is can be considered the brain of a computer. As the human brain controls all the body functionalities, the CPU does that for the computer. But there is a time when the CPU has to deal with a lot of tasks or heavy tasks. Then due to numerous processing, the processor gets too much hot.

Some claim that the safe temperature range is between 70-80 degrees Celsius. On the other hand, some claim that the range is only marginally safe because it is near 90 degrees, which is considered overheating danger threshold.

So, you can assume as 80 degrees Celsius is hot for a CPU and some CPUs may adjust this temperature while some may not.

Is 80 Degrees Celsius Hot for a CPU

Is 80 Degrees Celsius Hot Harmful to a CPU?

It is true that the thermal safety range varies on different processors. Various processors can bear various temperatures. For instance, the majority of Intel CPUs can resist temperatures up to 75°C, although some AMD CPUs can endure temperatures of more than 82°C. 

In general, a CPU temperature should remain between 45°C and 70°C to avoid overheating issues. It will be wise to not let your CPU exceed 80°C. Otherwise, it’ll get risky. 

This means, processors that can withstand up to 90°C, will not be troubled by 80°C. But lower-capacity processors will struggle at this temperature.

Why Does CPU Get Hot?

As electrical signals run through processors and convert to heat energy, the CPU becomes extremely hot in a little time. It follows that heat and processing power are directly related. When the CPU works harder to fulfill tasks, a lot more electrical energy is produced, which causes excessive heat.

So, at this moment, CPU damage is kind of inevitable. Your computer can suddenly stop working, leaving you helpless. The component’s overall durability can also be shortened by the high temperatures.

How to Monitor CPU Temperature?

Your CPU temperature can be monitored in a variety of ways. Some CPUs have built-in sensors that you may check using the BIOS or UEFI firmware settings on your computer. As an alternative, you can set up third-party applications to continuously track your CPU temperature.

You may get more specific information about your CPU from these applications, including its average and maximum temperatures as well as the temperatures of other components too. Such as RAM, graphics cards, etc.

Additionally, there are certain things you should take into consideration, for example, the workload on your CPU will affect its temperature. Also, your CPU temperature may be impacted by the room temperature.

How to Maintain a Lower CPU Temperature?

You may lower your CPU temperature in multiple ways. Here are some of them –

Clean the computer 

The only thing that moves air into and out of your computer is its fans. Dust and dirt are brought in by all this exposure to the air. Therefore, it’s crucial that you keep them in good condition. Numerous issues, like electrical problems and fan failures, may arise as a result of all this dust. Maintaining a low temperature becomes difficult when the fan fails. Therefore, clean the PC and fans.

Ensure better airflow

Having the proper airflow arrangement in your PC is one incredibly easy approach to guarantee acceptable CPU temperature. The ideal airflow pattern prevents air from becoming trapped or stagnant inside your PC case by having an equal amount of air entering as exhausting.

Choose cool environment

Placing your pc in a poorly ventilated place is another frequent cause of CPU temps to rise. Your CPU will become overheated regardless of how effective your airflow arrangement is or how efficient your case is for airflow if there isn’t any cold, fresh air reaching it.

Cable arrangement

In addition to CPU temperature control, cable arrangement confirms total temperature control. When attempting to produce a free-flowing, effective cooling environment, tangled cables might obstruct proper airflow and create object resistances that are unnecessary. Try to stick the cable with something in case they don’t spread much.

Use thermal paste

When attempting to reduce the temperature of your CPU, applying thermal paste might be very effective. Thermal paste should typically last several years. This figure varies depending on the circumstance. To ensure proper performance, you should swap out your thermal paste once every one to one and a half years. Or it’s advisable to reapply if you remove your cooler for any reason.

Frequently Asked Questions (FAQs)

Is 80 degrees Celsius hot for a CPU under full load?

The majority of desktop processors available today shouldn’t operate beyond 45–50°C when idle or 80°C when fully loaded. Although the CPU is working hard at 80°C, there is no cause for concern regarding long-term problems. When the temperature exceeds 80°C, that changes.

Is 80 degrees Celsius hot for a laptop’s CPU?

In the case of laptops, temperatures over 80°C are typically problematic over time, and temperatures over 90°C are dangerous. In this situation, thermal throttling downclocks the CPU to lower the PC heat.

Is 85 too hot for the CPU?

85°C is acceptable. But any angle greater than 90°C is not. Your CPU will suffer if the temperature rises above 90°C, and you will ultimately realize that your computer is throttling, lagging, crashing, shutting down, etc.

Is 80 degrees Celsius hot for a GPU?

A GPU’s normal operating temperature when gaming is between 70°C and 80°C. The game and visual settings may affect this, though. For instance, games with higher graphic demands might lead to the GPU operating at a higher temperature.


As you’ve come this far, hopefully, you’ve got a basic idea about the condition. In short, 80°C is a considerable level of temperature to hold under the full workload. But exceeding it in continuity may cause severe damage in a long run.
