How To Cool GPU?

An overheated GPU can harm other components, disrupt the system, and cause even more damage. In addition, a graphics unit can’t perform appropriately at its peak potential due to thermal mismanagement and you often have to wait for a game or software to load. If you’re facing this issue, you must know how to cool GPU and get the most out of it. For your information, an overheated GPU can hurt its cores wasting your money and time. Those who don’t know to check the issues with the card and maintain it at an appropriate temperature level must read this post until the end. 

It’s your duty to keep an eye on the GPU’s temperature and our responsibility to let you know all the crucial steps to take care of the graphics card. We have done thorough research and tested several GPUs before writing this article. Before starting to make some changes in your system or card, you must know the signs and symptoms of GPU overheating, how to spot them, and what you can do to cool your GPU down. Other than that, you must check all the possible solutions to solve the issues along with their appropriate method to apply to avoid any type of harm to the element.

How hot can your GPU tolerate?

Since GPUs are continually operating under demanding conditions that produce a lot of heat, they are built to withstand high temperatures. The amount of thermal paste used, ventilation, the age of the GPU, and the manufacturer all affect how much heat your GPU can withstand. In general, temperatures under 60°C are entirely safe for your GPU, while temps between 60°C and 90°C aren’t harmful, however, you should take additional cooling into consideration at the higher end of the scale. Hardware damage is very likely to occur at temperatures above 100°C. 

Why Does GPU Overheat?

The main causes of GPU overheating are as follows:

Overloading GPU: How much processing load you are applying to your GPU is the first sign of overheating. In general, your GPU will generate more heat the more work it is put through and vice versa. So, you must keep this fact in your mind before using the graphics card. 

Not Cleaning GPU: The second most typical reason for your GPU to overheat is the buildup of dust, dirt, and lint on its components. There is a good chance that poor cleaning is to blame for your GPU overheating unless you have a routine for doing so.

Insufficient Airflow: When your GPU is facing the wall, the airflow that helps it dissipate heat from the system is constrained. If there is insufficient airflow, there would be more heat production which ultimately makes it difficult for your GPU to cool properly.

Old Thermal Paste: High-quality thermal paste enhances heat flow from the GPU, maintaining the efficiency of its heat sinks. But as time passes, it becomes harder and prevents the heat from leaving the system. As a result, heat accumulates, which leads to your GPU overheating.

The signs of an overheated GPU

Some indications that your graphics card is overheating include loud fan noise, screen artifacts, and graphics-related issues. However, the same symptoms can also occur if your GPU hardware is broken or if your graphics card is out of date. As a result, you should use specialized software to examine the GPU temperature to determine whether overheating is to blame for these symptoms. You can also use some tools like Open Hardware Monitor, MSI Afterburner, and HWMonitor.

Some signs of an overheating GPU include the ones listed below:

Fan noise: As they work to dissipate the extra heat, overspeeding fans are one of the earliest and most obvious indications of GPU overheating. The GPU fans are under stress from overheating since loud noises imply that they are not functioning as well in removing heat.

Screen artifacts: If red tiles or other defects start to appear all over your screen, your GPU may malfunction. The artifacts of the screen are a symptom that your GPU is running above its peak potential and the temperature is way more than the safe limit.

Gaming Issues: When playing graphics-intensive games, if you encounter graphics-related failures like the graphics card not responding, the graphics card failing to recover from timeout, or anything similar, or whenever your game begins to lag, glitch, or crash.

Different Techniques for GPU Cooling

If your GPU is overheating, the steps listed below will help you cool it down.

Cleaning the GPU Fans

To help your GPU fans dissipate heat more effectively, give them a thorough cleaning, making sure no dirt or lint remains within. Cleaning fans safely involves using an air compressor or rubbing alcohol on the fan blades. Additionally, before reinstalling it on the computer, make sure it is completely dry.

Disable Overclocking

The GPU cores generate more heat the faster they are clocked. Therefore, if your GPU is overclocked, think about lowering its clock speed. Try running your GPU at underclocking settings to see if that stops the problem if it’s still heating up. Overclocking is not needed for an average gamer and only tasks that are very burdensome may require overclocking. It is advised to overclock as little as possible because it can affect your GPU considerably.

Limit GPU Overloading

If you can’t disable the overclocking then limit it. No doubt, running numerous graphics-intensive applications at once tends to overstress GPUs, which results in increased heat production. Overtaxing your GPU might destroy its fans and other parts in addition to making it overheat. So it is advised to carefully check the system requirements for the application or the game you need to run and act accordingly.

Hardware Inspection

Carefully examines your GPU’s fans to make sure they are not broken (although this is extremely uncommon). If they are worn out, replace them to address the overheating issue. Also, make sure that you thoroughly clean every component and look for loose wires. These might be some issues causing the GPU to overheat because it might not be having enough power or the airflow could be disturbed.

Boost Airflow

Has your computer begun to overheat after you just moved it into a home? In that scenario, ensure your GPU has adequate airflow to function properly. It is advised that you check the airflow of your room and also that of your case. Gaming cases are suitable for this problem as they are specially designed to keep heating issues at a minimum. Moreover, if you are able to buy a cooling system that would help you considerably.

Replace thermal paste

Depending on the caliber of the paste your GPU has, thermal paste does not lose its effectiveness after a few months and can last up to ten years. In order to improve efficiency, it will be helpful if you continue to think about changing the thermal paste on your GPU every three years. However, this is a difficult task.

Potential Solutions

The various techniques mentioned above enhance the heat transfer away from your overheated GPU. If they don’t perform as well as you expected, you might want to think about adding more fans to your computer case. You can increase airflow out of your system and minimize GPU temperature by adding extra fans. A water cooling system for your graphics processing unit may also be installed if your budget permits it. Your GPU temperature will drastically decrease if you mix air cooling with water cooling.


A GPU that operates at a high temperature for an extended period of time can harm other components of your computer. So monitoring your GPU’s temperature and keeping it cool will extend the life of your hardware. In the process, this post can help you get all the answers related to how to cool GPU along with other necessary information. For your information, it is common to observe GPUs becoming hotter with time due to a number of reasons. Continuous loads also eventually degrade hardware. Thus, you should be aware of the symptoms that indicate a complete GPU replacement is necessary. 

In contrast, there could be several reasons behind the thermal mismanagement of graphics cards. Each has its own symptoms and some of those are included in the related section earlier in this post. Other than that, you can take help from various steps to help your card keep itself cool. You must start with cleaning your cooling system, doing hardware inspection, and replacing the thermal paste. If it’s not working out, make sure to change the cooling system. However, those who can’t take this step can follow other given steps in the related section to get a better idea about the issues.
