“I wish my computer remains cool,” says everyone, but nobody likes computer overheating. Furthermore, if you suspect your system is overheating, how can you determine that it’s CPU temperature problem.

In this article, we will answer the below-mentioned questions.

  • Why my computer overheats?
  • what are the signs of CPU overheating
  • How do you cool down your CPU?
  • What happens if my CPU overheats?
  • What temperature is too high for a CPU?
  • How hot can a CPU get before it is damaged?
  • Lastly, how to fix the PC overheating issue?

No doubt CPU Overheating may lead to unexpected shutdowns, lost data, and serious hardware damage. But computers are designed to disseminate normal heat.

To counter CPU overheating PC has a built-in ventilation system as well. So, every heat which PC generates is not dangerous. In this article, we’re going to look deeply at the causes of CPU overheating when it can pose a serious threat.

How PC Generates Heat?

CPU Overheating

Normal electricity is required for the CPU to perform regular tasks. Using electricity CPU uses the arithmetic logic unit to execute the command. Two Components that is, the Central Processing Unit (CPU) and the Graphics Processing Unit (GPU) consume most of the voltage.

That’s why they are prone to generate more overheat than any other component and may cause CPU overheating.

Overclocking is another factor of CPU overheating. Through this process, the PC generates more heat. If you ask what overclocking is? It’s to run the CPU or GPU at higher clock speed than prescribed by its default settings.

No doubt the performance increases in this process but ultimately the CPU and GPU overheating also increases. To counter this problem of CPU overheating, some use the process of underclocking.

How Your PC Lowers its Temperature

CPU Overheating

Computer components generate heat during normal use, that’s why several cooling systems are built in most PCs to mitigate CPU temperature. The airflow is one of the most common cooling systems.

All computer cases draw cool air from the outside and expel hot air that builds up in the case. In this way, the chances of CPU overheating are reduced.

But how the main airflow works in your PC, depends on the computer’s case and design. Ordinary computer case has a single PC fan with vents on both sides.

To counter CPU overheating on high-performance PC’s, you’ll likely see more than one intake and exhaust fans designed with the purpose to deliver proper airflow all over the interior components.

CPU and GPU are the biggest heat generators and have additional cooling systems placed on them. Usually, a heat-sink is attached to CPU that’s designed to pull heat off the processor and an attached CPU fan throws that heat away from the CPU and heat-sink.

What are the Signs of CPU Overheating?

CPU overheating

As already explained, the computer does generate normal heat. But if someone wants to know what an overheating computer looks like? Then I must say that there are different signs/symptoms of CPU overheating which tells you that “yes” your PC is dealing with CPU overheating.

Usual signs of CPU overheating include PC shuts down abruptly, blue screen of death (BSOD) appears, PC freezes, unusual fan sound or PC becomes sluggish.

A simple test to check whether it’s PC overheating or not is by feeling the high CPU temperature which it emits from visible components. If they are overly hot, it means there is a problem of CPU overheating which needs to be fixed.

Other signs of CPU overheating vary from computer to computer depending upon different models. In almost every computer there is a fail-safe that acts as a fuse in the circuit.

It shutdowns the PC when CPU temperature goes up, and then PC remains off until it cools itself down.

General causes of CPU overheating

The causes of CPU overheating can be divided into two categories in order to understand it better.

Internal Causes

CPU Overheating

The main reason why computer overheats is when there is a damaged fan or inadequate cooling system. Old CPU placed inside PC can also prove to be another cause.

In recent years, the quest for making a more powerful PC has also caused a problem of increased GPU overheating & CPU overheating.

Other common causes of the CPU overheating are watching movies, playing games, doing graphical work, Burning CDs, etc. To mitigate the problem of computer overheating you should improve the air cooling system or liquid cooling system.

When you play high graphics games with low PC spec it also causes GPU overheating.

Overclocking of CPU & GPU is another cause, this technique is used to enhance the performance of CPU. Overclocking in simple terms means, to run the CPU/GPU beyond its actual limits prescribed by its manufacture.

This process does enhance efficiency but at the same time, it causes CPU overheating.

External Causes

CPU Overheating

Apart from the internal component which adds up to the CPU heat problem, there are other external causes as well.

Like the poor location of the Computer and ventilation of the room also raises the concern of CPU overheating. Because in summer or in closed room access to fresh air is a problem.

Inadequate ventilation in computer cases is another factor which causes computer overheating.

Sometimes dust accumulates within cases that prevent the circulation of air in computer cases. Ventilation in the laptop is a serious problem because there is a narrow space between components.

That’s why the chances of laptop overheating are more as compared to desktop PC. But you can fix this overheating problem if you regularly clean your computer.

Insufficiency of a cooling system in computer cases is another problem. Usually, there are three PC fans placed inside. But if heat accumulates in a computer case then there’s needs to improve the existing PC air cooling system.

You can also increase the fan speed using a free temperature monitoring program like Speefan for windows. If you are mac users than macs fan control is the best software to deal with air cooling issues.

How Hot Is Too Hot for PC?

Electronics by its nature exudes heat, and it is the same case with a computer. Each task that is given to PC puts some stress on CPU, GPU, Hard Disc Drive (HDD), and Optical Disc Drive (ODD), but one should not get paranoid on normal PC heat.

But if fans are working for a considerable time and make noises then this is a sign of CPU overheating. On the other hand, where the fan does not work or broken is another story to be told at a later time.

In windows, there is a built-in program called resource manager it shows which application is consuming more memory and causing more CPU heat. Try this application to trace the source of the problem.

Normal CPU Temperature For Better PC Performance

There is no hard and fast rule which tells us about what is the best CPU temperature? Or what is a safe CPU temperature because each PC, CPU, and GPU model varies.

But the computer technician still tries to tell us the average CPU temperature. Scientifically speaking, CPU temperature should range between 20°C/68°F to 26°C/79°F to avoid CPU overheating.

It is a good temperature for PC. But once it goes beyond 70°C, it can damage the computer. Another study shows that normal CPU temperature should be around 60 degrees Celsius, but the ideal CPU temperature is considered between 45-50 degrees Celsius.

For playing games, normal GPU temperature should be around 80-degrees Celsius. At that PC Temp, chances of GPU overheating are low. For playing games normal CPU temperature is 70 C°, it must not exceed from that point.

Latest Intel and AMD laptop, and desktop CPU’s have the ability to work at a maximum temperature of 100° Celsius. But continuously running PC on 100 C° will cause CPU overheating.

How to Check CPU Temperature?

CPU Overheating

If you suspect your system is overheating, how can you determine the CPU temperature? The answer is simple. If you suspect that your CPU is overheating, but you don’t want to install any CPU temperature monitoring software to check CPU temp if it’s computer overheating than there is another way.

Use system BIOS and for that restart your computer. When the Windows icon shows up press the “delete” key to enter in BIOS. For those who want to check CPU temperature Windows 10 or Windows 8, they can press and hold “shift key” when clicking restart. That way a new advance startup mode will show up.

Once you enter the system BIOS check BIOS menu, there you should be able to find a menu which deals with Computer hardware monitors and CPU temp. In it, you can see a field which shows maximum CPU temperature your system can have. This method only tells you what is the CPU temperature of your PC but it does not control CPU overheating. For that, you have to use a third-party CPU temperature monitor.

There are many CPU temp monitoring software which is easy to control. These CPU temperature gadgets can tell you what is the temperature of CPU and GPU while doing some burdensome task. Some of these CPU heat monitors even allow you to control CPU fan speed this way you can lower the chances of CPU overheating.

The best CPU temperature monitor software for Windows 10/7 are Core Temp, HWMonitor, Speedfan, Real Temp, Open hardware monitor, Rainmeter, CPU thermometer, Speccy, AIDA64 Extreme, HWiNFO

To fix the CPU overheating problem first remove the side panel of the computer but before doing so switch off the PC. Usually, this simple method solves the CPU overheating problem. Because more fresh air will quickly pass through PC components as a result decreases PC heat.

Regularly Clean Your PC

CPU Overheating

To avoid CPU overheating, build a habit to regularly clean your PC. Because dust particles and debris accumulate in the PC case which blocks the passage of air from the surrounding. In almost all overheating the computer, there is a piled up dust in it which prevents effective airflow. To prevent overheating regularly clean your computer, for that you should buy a can of compressed air, mechanical oil dropper. Carefully remove dust from heat-sinks and power supply fans. This method will surely help in decreasing the problem of CPU overheating in the computer.

Ensure Whether Fans are Running Properly

CPU Overheating

Usually, there are three fans installed in every computer even failure of one fan can increases the chances of CPU overheating. These three fans are located on the CPU, power supply unit, and back of computer casing. If you are facing computer overheating then there might be a problem with one of these fans. To solve this problem open the computer case and check if the fan is broken or is unplugged. Immediately fix the PC fan otherwise excess heat will damage the internal components of your PC.

Liquid Cooling System

CPU Overheating

The liquid cooling system is an alternate method to lower the CPU overheating threat. The water cooling system performs more as compare to the common air cooling system. Usually, those who overclock CPU to gain more performance uses a liquid cooling system. If you have installed this type of cooling system then you should properly check it. If it is leak than it will fry your internal hardware.

There should be enough space For Ventilation in a computer case

Remove blockades from the front and back of the computer casing. It will increase the flow of fresh air and fix CPU overheating.

Conclusion

Unless heat which CPU generate is excess CPU overheating is not a problem. Any PC can benefit from simple measures mentioned above to lower computer temperature. Usually, the major causes of CPU overheating are overclocking, old hardware, and a faulty cooling system. Apart from that graphics card overheating is another factor of PC overheating. To avoid PC overheating you should always maintain ideal PC temperature within PC which is 45-50 degrees Celsius.

If you want to check which component is causing computer overheating. There are many CPU temperature monitor software. To prevent CPU overheating there are different computer overheating solutions to cool down the computer. Like, sufficient airflow, by removing computer cases, cleaning computers regularly. Always remember, before you put your computer under strain you should have proper means to overcome the overheating problem.

As they say “prevention is better than cure.”
