Can Overheating CPU Damage Motherboard?

Playing games and rendering videos on your PC can be all fun, however, the real problem arises when it overheats. There can be many questions in your mind at this point like an overheating CPU damage the motherboard or how to fix this. 

I had been going through this situation for the past 2 weeks and this time I was literally concerned. I instantly switched off my system and looked around for various signs of why my PC might be overheating. Here in this article, I will be explaining everything you need to know about whether overheating a CPU can damage the motherboard or not.

Can Overheating CPU Damage Motherboard?

Overheating is not known to damage the motherboard. However, it can cut short the lifespan of a motherboard. If you notice any damage to your motherboard, make sure to contact an authorized service provider. It is not always easy to tell if your computer is overheating. You may think your computer is running fine, but you may actually be causing some damage.

In extreme cases overheating can cause the motherboard to burn out, and also short out the components on the motherboard. If this happens, your motherboard will no longer be able to process signals. It will not be able to boot up properly, and you will not be able to access data on the hard drive.

Why Is My CPU Overheating?

There are a few reasons why your CPU may be overheating. Here are some probable reasons why a CPU might be overheating.

CPU Producing A Lot Of Heat

If the CPU is producing a lot of heat, it could mean that you have installed too many components on the board or that your power supply is not supplying enough current to the motherboard. It could also mean that there is something wrong with your fan.


Overclocking can cause a CPU to produce more heat than usual. Overclocking your CPU will allow you to achieve higher speeds which will require more electricity.

Fans Not Working Properly

Can Overheating CPU Damage Motherboard?

You may have fans that aren’t working properly and are not cooling your CPU. This is very common with video cards and graphics cards. The best thing to do is check the fan speed and make sure that it is working properly. 

Thermal Compound is Outdated

If you are using an old thermal compound, then it could be a good idea to purchase a new one. If you are overclocking, you should use a thermal compound that has been updated. This will help reduce the chance of overheating. 

Faulty Heatsink

If the heatsink is not large enough or has a faulty fan, this can also cause your CPU to overheat. If the heatsink is damaged, it can cause your motherboard to overheat. If you are overclocking your CPU and it is producing a lot of heat, then it could be a sign of a faulty heatsink. Try cleaning your heatsink with a soft cloth to see if this improves the situation.  

How Do You Know Your CPU Is Overheating?

If your CPU is overheating, you may notice a decrease in performance or an increase in heat output. You can also check your CPU temperature by using a thermal monitoring device. If your computer is overheating, you will likely see an increase in CPU temperature over time. Overheating is caused when your CPU is not getting enough airflow to cool itself off properly.

This can be caused by a clogged fan, blocked air vent or the CPU being too close to the exhaust of the computer case. To check your CPU temperature, you can use a thermal imaging camera. A thermal imaging camera will show you what is causing your CPU to overheat and which fans are not working.

What To Do When A CPU Overheats?

If a CPU overheats, the best thing to do is to shut it down and allow it to cool down. If the heat is severe enough, you may even want to replace it. The most common cause of overheating in a computer is running it too hard, or at the wrong speed.

When a computer is working hard, it has to use more power than normal, and it generates extra heat. This excess heat can damage the computer. A computer overheats if its temperature rises to a level that causes it to become unstable.

What Temperature Can Damage A Motherboard?

The ideal temperature for a motherboard is between 68 to 176 degrees. Anything above this can damage the motherboard. The motherboard will usually start to have problems when it gets to around 160 degrees. This is because of the way that they are designed.

Most motherboards have a heat sink on them. This is to prevent the temperature from getting too high. A good motherboard should be able to handle a temperature of 170 degrees without any problems.

How To Cool Down Overheating CPU?

Can Overheating CPU Damage Motherboard?

There are a few things you can do to cool down a CPU that is overheating. You can open the case and remove the CPU, or you can use a cooler to help cool the CPU. Here are some other things you can do to cool down an overheating CPU.


Proper ventilation will aid in cooling your CPU in no time. If you are a heavy overclocker, it’s also important to ensure that the ventilation in your case is sufficient to dissipate the heat generated by your CPU. If you have an air conditioner, make sure it is able to cool your PC.

BIOS Update

It is recommended to update your BIOS to the latest version, as this could help to improve cooling and fan speed. It is also recommended to disable any unnecessary features of your BIOS such as CPU power saving or thermal throttling, which could cause unnecessary heat generation. 

Installation Of Heatsink

You can install a heatsink on your CPU for better cooling, and you can use a fan to blow air over it. Heatsinks come in different sizes and prices, depending on how big your CPU is. It is advisable to choose a heatsink that is compatible with your motherboard and CPU. 

Can A Faulty PSU Damage Motherboard?

There is no evidence that a PSU can damage a motherboard. However, if the PSU is not properly installed or if it has been damaged, it could cause problems with the motherboard. Power supplies are the most important components in any computer system. Motherboards control how the CPU, memory, and other parts of the computer work together. They regulate the voltage and current needed to make sure the parts in the computer function correctly.

Can Bad RAM Damage the Motherboard?

While it’s theoretically possible, in practice it’s unlikely that a bad RAM can damage the motherboard. The only way a motherboard can be damaged due to bad RAM is if a RAM chip goes out of specification and causes a short circuit between two pins on the motherboard.

This would be like having a defective IC socket. But in this case, there would be an obvious problem in the system. For example, the computer will not turn on at all or it may only boot into safe mode.

Can Dust Damage Motherboard?

Dust can damage a motherboard, and if the dust is not cleaned off the motherboard soon enough, it can cause permanent damage. Dust on a motherboard can cause serious problems. If you have dust on your motherboard, it can short out components on the motherboard and cause permanent damage to the motherboard.


So, now you know that overheating can damage the motherboard. You better be taking care of your CPU. To remain at the safer side make sure to look after the ventilation system of your CPU and invest in some good aftermarket CPU coolers.
