As you know, you cannot build a good PC without a suitable motherboard.

Of course, you can buy the most expensive CPUs and GPUs. But if those parts are not compatible with your motherboard, it is a waste of money.

More importantly, connecting not-so-ideal components to a motherboard does not always end well. And one of the most common issues is the high temperature on the board. 

A lot of people panic when they find that the motherboard temperature is high on their computer.

As much as it is a usual reaction, panicking is not going to help you. However, following proper techniques to find the cause of the high temperature and fixing it (or them) will. We created this guide to help you with that part.

We have covered the most common reasons for the high temperature on PC motherboards and illustrated how to fix the issue.

We believe this guide will help you keep your PC’s motherboard in the best condition possible.

Why Does Motherboard Temperature Go High?

Why Does Motherboard Temperature Go High?

We will first explore why your PC’s motherboard is registering high temperatures in the first place. Based on the PC build, any of the following factors may cause the temperature to go high.

However, before exploring specific reasons, we must understand a few things about a PC motherboard and its temperature levels.

As you know, the motherboard is connected to almost every component on your PC. The list includes CPU, GPU, RAM, storage, and hundreds of other tiny things that make your PC work. More importantly, many of these components are installed on the motherboard.

The RAM, GPU, and CPU will be the best examples. So, when these components work and produce heat, which they always do, the extra heat is passed onto the board. Therefore, when your activities take a toll on your computer’s resources, the same will reflect the motherboard temperature.

For instance, we can consider the case of AAA gaming titles. When you run these games in the best possible quality, your PC uses maximum resources from the CPU, GPU, RAM, and storage.

Running all these parts at the highest or close-to-highest speed means the temperature will rise. Collectively, these components will cause a noticeable hike in the average temperature of the motherboard.

You have to understand that it is a common thing. So, you do not have to worry about the issue. If your motherboard temperature stays under 60 Degree Celsius, you do not have to worry.

However, if you see that the temperature crosses the limit, you have to see if other issues are causing the board to overheat. Some of the common reasons for motherboard overheating are as follows.


Overclocking is one of the common reasons why the motherboard temperature is high.

Overclocking your CPU/GPU means running the component at best possible speed. Based on the wattage of the chip, overclocking can push the temperature to an unprecedented high.

Therefore, if you always run your CPU/GPU at overclocked speeds, you can expect the motherboard temperature to shoot up. It may happen when you overclock RAM as well. However, it may not contribute as much heat as CPU or GPU overclocking does.

Lack of Ventilation

Lack of ventilation is the next probable reason why the motherboard temperature is high. Like any other component, the motherboard maintains a reasonable temperature with the help of ventilation and cooling. It means the hot air from the different components is pushed out of the PC case as soon as possible.

Therefore, if the ventilation system is faulty, it will cause the temperature to stay high. It may also happen due to a low number of cooling fans or a non-functional cooling system. Then, again, it all relates to a holistic approach towards ventilation.

Voltage Issues

Voltage issues with the motherboard or the PSU can also cause high temperatures on the board. If the PSU cannot supply the correct voltages to different parts connected to the motherboard, they may release an unprecedented amount of heat. In the grand scheme of things, it will lead to high heat from the board.

You may come across this issue if you are not using fully compatible hardware with the motherboard. Therefore, if you see a constant high temperature on the board, you must check whether the board receives the correct voltage from the PSU.

Heatsink Problems

Heatsink problems also lead to high motherboard temperatures at times.

If you did not know, almost every motherboard comes with a heatsink. This heatsink is designed to push out the heat generated by the motherboard circuitry. Usually, the heatsink may not require a dedicated cooling system. It may not be the case when you build a performance-friendly PC, though.

In that case, you will have to see if the heatsink can manage the high amount of heat. In addition, installation problems with the core heatsink will also send the temperature to a high level.

Manufacturing Defects

Manufacturing sefects are also found to cause temperature issues on motherboards. You can detect whether your PC’s motherboard has problems using a few pointers. First, the motherboard may run at a high temperature even when the PC is idle.

Second, you may find that components connected to the motherboard are constantly failing. If these issues persist even after voltage checking, there could be an inherent problem with the motherboard. So, the best thing you can do is get in touch with tech support and probably get a replacement motherboard.

As we said, these are generic issues. There could be many issues exclusive to the model of the board your PC is using. However, it is impractical to list all those issues. Therefore, we think you should get started with these pointers.

Does High Temperature Damage My Motherboard?

The short answer to this question is Yes.

Constantly running the motherboard at a high temperature might lead to hardware damage.

However, the specific nature of the damage would depend on a few factors. One common thing is that heat trapped within the motherboard infrastructure does not help anyone.

Depending on where the heat is situated, the issue may further cause specific damages. For instance, some CPUs and GPUs are not designed to survive super-high temperatures. Therefore, you may face problems like thermal throttling and lower performance levels.

So, if you find that your PC’s motherboard temperature is high, you must try to solve the issue as quickly as you can. Fortunately, you can find many ways to go about it. Once again, we will list some of the most useful methods to follow.

How To Decrease Motherboard Temperature?

You can use the following steps to decrease the temperature of the motherboard. Depending on the exact situation, you may have to combine a few methods.

Solution #1

The first solution is to disable overclocking and run your PC at standard settings. Then, if the motherboard is heating up due to the excess working of the CPU, you can solve the issue right away.

Based on this feedback, you will have to get a new motherboard or replace the CPU. You can make this decision based on what you want to put first: performance or stability.

Solution #2

There are times when you cannot compromise performance. In that case, the best solution to decrease the motherboard temperature is enhancing the cooling options.

You may have to replace the existing air-cooling system with a liquid-cooling system, perhaps. Along these lines, you can also try installing more fans on your PC case.

Solution #3

In the next step, you should check the motherboard for manufacturing defects. There could be a few issues that send the temperature high. For instance, you should see if a BIOS update is available for the board.

In many cases, manufacturers roll out bug fixes through these updates. So, by running the BIOS at the newest version, you can decrease the motherboard temperature.

Solution #4

As we mentioned, the problem could be with the PSU as well. Therefore, we do not recommend using a random-picked PSU on your computer.

Instead, you should get one of the branded products from the matter. These Power Supply Units will ensure that the motherboard receives the correct amount of power into every part. In the long run, it means a stable PC experience.

Solution #5

As a part of these steps, you should confirm whether the heatsink and integrated cooling systems are fine. If not, you will have to replace the same with a better cooling system.

In short, you may have to upgrade the ventilation system to keep the system running in better health. Nevertheless, we believe this is a worthy investment from the performance point of view.

If these solutions do not solve the problem, you should get in touch with tech support. You may have to get the motherboard repaired or replaced. If you had bought the motherboard from a trusted manufacturer, you would not have to worry since warranty benefits will help you.


As you can see, you can do better things than panicking when the motherboard temperature is high.

Yet, we should warn you that you must be ready for necessary upgrades. These upgrades will make sure that your PC can maintain proper health without any impact on performance.
