How Hot is Too Hot For CPU? What’s The Ideal Temperature?

How much hot is too hot for the CPU? Generally, any temperature above 27 degrees Celsius is dangerous for your CPU. But your computer will surely break down if the heat reaches 75 degrees Celsius.

It might happen often that your CPU got so hot that your computer couldn’t take it and shut down in the middle of whatever you have been doing. This might be a big problem if you were doing something super important.

So, to ensure a healthy life for both your CPU and computer, you need to make sure that the processor is not taking too much pressure and the heat temperature is under control.

In this article, I will talk about everything you need to know about the CPU generating heat and what steps to take to stop it from overheating.


How Does Your CPU Generate Heat?

Heat is generally produced by the electricity that flows into the components. Mostly, anything in an electrical device, whether it’s a computer or an engine, the energy motions inside will easily create heat transference.

But the energy depends on the task you are using the computer for. The heat, in most cases, greatly affects the inner components like the central processing unit (CPU) and the Graphics Processing Unit (GPU).

Overclocking can be one of the many reasons for your CPU to get excessively hot. This happens when you try to make your CPU work at a higher clock speed than the manufacturers recommended.

In this case, you will have to have a good idea about your CPU’s clocking rates. Overclocking usually makes the operating system faster and more efficient than ever. But the problem occurs in the high voltage that your processor uses. This is what causes your CPU to generate more heat.

Moreover, doing heavy tasks like watching DVDs, sharing large files frequently, or playing high graphics games can have a huge impact on the CPU that, in most cases, results in overheating.

Some PC owners also try to solve the problem using underclocking. This decreases the heat transmission inside the processor by replacing the oscillator crystal.

While this is an effective process, it can also hurt the system’s efficiency. Nothing can work better than turning off the computer to give it a rest.

How to Know If Your PC is Overheating:

Though the heat can harm your CPU, I am pretty sure your computer doesn’t get overheated every day. So, how to know the difference? One of the main symptoms of that is your computer freezing randomly while working.

Also, the fans inside your PC can start to make more noise than usual when there is a lot of extra pressure on the processor and motherboard. This happens because the fan tries much harder to get the hot air away from the accessories using the heatsink.

Moreover, most computers have a fail-safe that shuts down the overheating components to prevent permanent damage. It can also happen that your whole computer has shut down and refuses to restart unless it has cooled down completely.

Then also, you can turn away the possibility of the PC breaking down due to some hardware problem.

There is another way for you to know if your CPU is overheated. For that, unplug the electricity’s computer and gently touch the components. They can be tough but not so hot that you can’t touch them.

If, by any chance, you cannot touch the parts, you can be sure that the computer has overheated.

Know if the CPU is overheated or it’s just hot:

Though I already mentioned the ways to know if your CPU is overheating, the symptoms don’t always show up because of your CPU’s overheating problem. Now, any kind of heavy task will surely raise up the processor’s temperature. In these cases, your computer will generally produce heat without causing permanent damage.

While your fan working with a rather noisy speed often means overheating, it’s also possible that the fan is broken. So, the main way to realize whether your CPU is overheating depends on your PC’s performance and efficiency.

In most cases, your computer will go completely slow when trying to do normal tasks like running two programs at a time or opening several tabs at once. Also, your computer can be shutting down and restarting frequently without any work, making it difficult for you to do anything. And if there’s a Blue Screen of Death, you must find the solution as fast as possible!

But again, you can leave out the possibility of malware or malicious software harming your PC’s performance. So, it’s better if you take the necessary safety measures.

Now, on the Windows operating system, you will have the option to check which applications are the most CPU intensive with the help of the Resource Monitor. You can search for the app on your desktop and get a list of the apps running in the background. The list can be pretty long, though!

A broken fan is one thing. But poor airflow or blocked airflow due to misplaced components can be a big cause for your CPU’s overheating. Moreover, you should always place your PC in an open place since an enclosed space can trap the heat inside, clogging up the vents.

How Hot Is Too Hot For CPU?

Most computers are built to work at their maximum power at room temperature, which means it’s neither too cold nor too hot. Technically, a normal room temperature is between 20 Degrees and 26 Degrees Celsius (68 degrees and 79 degrees Fahrenheit), which comes to an average of 23 degrees Celsius or 73 degrees Fahrenheit.  And anything that exceeds 27 degrees Celsius or 80 degrees Fahrenheit damages your PC.

While cold weather is not generally harmful to your PC, a temperature under 20 degrees Celsius is something to monitor. You can use a simple mercury thermometer to monitor the temperature.

So, watching your CPU accessories through the Unified Extensible Firmware Interface (UEFI) or the Basic Input/Output System (BIOS) is better.  So, how hot is too hot for the CPU? It will stop working after reaching &5 degrees Celsius or 167 degrees Fahrenheit.

How To Maintain A Safe CPU Temperature?

Keeping your PC cool isn’t only the key to excellent efficiency but also essential. But don’t worry, as keeping your CPU cool doesn’t require much from you. In some cases, just opening the nearby window may work!

The simplest solution may be moving your computer a bit to avoid any kind of blocked vents or unwanted dust. Or, you can move it to a cooler room in summer when the temperature is unbearable.

While laptops are generally easier to cool than desktop computers, they can also be harmed by the excessive heat generated due to the narrower vents and smaller heatsinks.

Installing your own fan can be a good way to prevent your CPU’s overheating, which is not recommended since you don’t know how that will affect the internal components. If by any chance, the fan fails, it might cause the inner components permanent damage.

So, it’s better to ask a professional to fix the fan. But the better solution is to give your computer a little rest every time you use it excessively. If you think your work is getting heavier than the computer can handle, try adding some extra RAM.

What is The best temperature for your CPU?

As I mentioned earlier, 23 degrees Celsius or 75 degrees Fahrenheit is the ideal temperature for your computer. But it can be harmful if it reaches more than 27 degrees Celsius or 73 degrees Fahrenheit.

Subsequently, the CPU temperature should not exceed 75 degrees Celsius or 167 degrees Fahrenheit. Hence, nor colder than 20 degrees Celsius or 68 degrees Fahrenheit.

Ways to Keep the PC Cool

There are several ways you can use to keep your PC cool and avoid the problems of overheating:

  • Always make sure that the computer is well ventilated.
  • Clear the fans and vents from any kind of dust
  • Always give the PC a rest after a long-time use
  • Keep the computer in a cool room

You should always monitor the temperature of the CPU in case things get out of hand and your CPU needs your special attention.


An overheated CPU is way more dangerous than you might have guessed. Especially, your computer stays at the risk of getting down due to the problem. So, you should always have a good idea about how hot it is too hot for the CPU.

Now that you know the ideal temperature for your CPU, you should monitor the heat generated by your PC and make sure that it doesn’t get overheated.

Follow the steps and ways I mentioned above, and I am sure your problem will be solved in no time.
