Why is GPU Overheating: How to tell and fix

Why is GPU Overheating

Is your GPU facing overheating problems, and are you willing to overcome the heating issue? If yes, you are at the exact place where you need to be. Undoubtedly, a GPU is the most expensive component of the computer system, and it plays a great role in managing the overall performance of the computer.

That’s why you must maintain it properly and eliminate all the heating problems because no one wants to damage their expensive component due to overheating. Before controlling the heat, you must be aware of the major reasons that cause overheating.

Major reasons why GPU is overheating:

GPU is mainly designed to handle high temperatures of the system while performing heavy computing tasks. However, there is a temperature limit that a GPU can control. GPU becomes overheated when the system exceeds that limit, damaging various components. In this manner, you must focus on controlling the overheating problems. On the contrary, several major reasons heat the GPU. Here, these reasons are:

  • Poor flow of air:

Here, the first overheating reason is the wrong direction of the GPU. For instance, there will be insufficient airflow if you face your GPU towards the wall. The wall will restrict the smooth airflow, and the heat will not eliminate properly. As a result, the GPU will not cool down efficiently, and the temperature will increase.

  • Overloading GPU:

Secondly, as we already discussed above, a GPU can handle a temperature limit. In this sense, you can say that overheating also depends on how much processing load you are putting in the GPU. Well, try to maintain the overall load because a higher load generally results in overheating problems of the system.

  • Lack of maintenance:

Thirdly, the GPU’s lack of maintenance and cleanliness can stuck heat and affects the airflow, which results in overheating. In addition, the presence of dust and dirt on the GPU hardware can damage the system. In this way, you must focus on cleaning your GPU regularly with a piece of cloth.

  • Hardware:

Undoubtedly, hardware is another component of the GPU that you need to consider while checking the heating problems. The dirt and dust of the fan can affect the performance of the GPU.

The following steps should be taken to prevent GPU overheating:

Pressingly, there are several things that you need to consider while eliminating the overheating problems of the system. Thereby, it is more important to focus on the exact reason for the overheating. In this sense, we are here with a few things that you need to check while considering the overheating problems of the GPU. Here, these considerations are:

  • Airflow of the GPU:

First of all, you must make sure that the air is flowing smoothly from the system and the face of the GPU is away from the border as you know that the air requires enough space for a smooth flow. So, we indeed suggest you keep your GPU in a safe and wide space.

  • Overall Loading:

Pressingly, you must avoid loading your GPU. According to the latest research, running multiple graphic tasks on GPU can disturb the system. All you have to do is just put a balanced load on your GPU to achieve impressive performance.

  • Overclocking:

Well, run the system at a medium speed to avoid overheating problems. Besides this, you must keep in mind that the higher speed of the GPU produces more heat. In overheating, try to reset the speed to resolve all the problems.

  • Thermal paste:

Lastly, we suggest you replace the thermal paste if you are willing to achieve better efficiency. So, you must try to replace it after every 3-4 years.

GPU Overheating For No Reason:

In some cases, you may not find out the actual reason for the overheating of the GPU because the Heat sink, thermal paste, loading, and other factors are working in a balance. At this point, you may get confused and prefer to replace your GPU, but the problem can be with the lack of maintenance.

But, if all other components are working smoothly and you are still facing overheating issues, then the presence of dust and dirt is causing problems in the functionality.

In addition to this, the high temperature can cause overheating. In this sense, a temperature below 60°C is entirely safe for GPU. Above this limit, the system heats up quickly.

How to fix graphics card overheating:

For fixing the overheating of the graphics cards, you must follow all the steps mentioned below:

  • Clean heat sink:

Primarily, clean the heat sink of the GPU for cooling it efficiently. Furthermore, the cleaning of the sink removes all the dust and dirt stuck in the system.

  • Overclock:

In case if you run the GPU at a very high speed, then the input may not match the output timing. For controlling the overclocking, turn off the GPU for some time and cool it down completely.

  • Use Thermal Paste:

Undoubtedly, the thermal paste can work wonders in cooling down the GPU. Over time the thermal paste becomes dry, the Connection Between GPU Chip with Sink heat will not be strong enough to transmit heat, and in the end, GPU will get Overheat. I preferred to replace the old thermal paste with a new one at that time.

  • Overload:

After this, check the driver issues and avoid overstressing the system. Besides this, never try to perform several tasks of graphics games at the same time.

  • Fix hardware issue:

Lastly, I prefer to fix all the hardware issues by cleaning them regularly. In addition, clean the fans properly.

Frequently Asked Questions:

What should you do if GPU is overheating?

If your GPU is overheating, you must reduce the system’s temperature. After this, turn of the clocks for sometimes.

How to tell if GPU is overheating?

Pressingly, the fan noise, screen artifacts, and gaming errors are the main factors that tell the overheating problem of the GPU.


Mainly, an overheating GPU can damage several components of the system and result in the system’s instability. This article can help you a lot to avoid all the unwanted issues. By reading this article, you will know the major reasons for the overheating problems and the proper solutions to overcome them.
