How to cool down GPU?

by Linda D. Yelverton

The Graphics Processing Unit is one of the most important parts of a Computer. It helps us view the best images, videos and even animations.

It is our primary responsibility to monitor the functioning of this system and take necessary actions in case of any default. What is the temperature that the GPU can sustain? How to get the GPU temperatures down? Do we have many alternatives? Let us check the background details and understand the different methods that can help us maintain the GPU temperatures.

What is the ideal GPU temperature?

Graphics card in different computer systems has unique specifications with diverse cooling systems. Hence, there is no specific range of temperature that can be mentioned for all GPUs.

To be a little precise, on an average the GPU temperatures can be around 30 – 40 degrees Celsius when idle and somewhere around 60 – 85 degrees Celsius on heavy load. In some cases, during gaming sessions, the temperatures can go up to 95 – 105 degrees Celsius when the System automatically switches off. Optimally, considering the common manufactures Nvidia and AMD it is good and safe enough to maintain the temperatures at 85 degrees Celsius even under extreme load conditions.

Methods to cool down GPU

Firstly, we need to know how to check the GPU temperatures. BIOS is one of the effective methods to check the GPU temperatures. However, it requires a complete restart of the system and the temperature during heavy load cannot be viewed. There are plenty of software systems that can be installed in our system to know the temperature.

Further, let us get onto the different alternatives to cool down the temperature in case if it goes excess.

  • Ensure better airflow

One of the common problems that every GPU faces is the insufficient airflow within the case. The fan systems require a close watch at this stage. Fewer fans or sometimes too many fans can bring in dead spots that decline the air flow efficiency. Check for the fan systems and add or reduce the number of fans appropriately. Also replace default fans without any delay.

Every case will have fan slots that are connected to the fans. It is always advised to fill up all the slots with fans to ensure better efficiency in air flow. This can improve the temperature issues during gaming sessions.

  • Cleaning the interiors


It is always suggested to regularly clean the interiors of the GPU to improve its performance and fight issues that come due to increased temperatures. Disassemble the graphics card by carefully removing the screw. Remove the fan gently and clean it with compressed air to get the dirt completely out of the system. Clean the interiors of the card with a clean wet cloth and assemble the parts finally.

How to Lower GPU Temperatures

  • Check the thermal paste

Thermal pastes get dried out on extensive usage. Replacing it at the right time will certainly resolve the issue. However, it is very important that you read through the different products available in the market and choose the best that will suit your system and budget as well. Also, read through the guidelines before applying the paste. These factors are important to give the ideal temperature output for the entire system.


  • Water cooling system


Sometimes, we overclock the GPU system to increase operating efficiency and enhance the performance of the GPU. It brings effective change in the quality of images and the graphics we see. However, this can over strain your GPU System and tend to overheat. The water cooling system is the best way to cater to these issues. It can lower the temperature to the extent of fifty degrees Celsius.

There are also third party software systems that can be installed in your computer to reduce the GPU temperatures considerably. Look out for the best options and verify if it will work for your GPU specifications and further go underclocking the system.  MSI Afterburner is an effective tool that can be helpful in this regard. It has additional benefits such as increasing the lifetime of the product and decreasing the power consumption as well.

In addition to maintaining the GPU temperatures, it is essential to concentrate on CPU temperatures as well.

How to reduce CPU temperature?

The CPU temperature is another prominent factor that needs to be monitored. The CPU temperatures increase as more applications and processes run through the system. Let us discuss some methods to lower the CPU temperature.

  • Enhance the air flow by upgrading to a better fan with soaring revolutions per minute. This will certainly keep the temperature at an optimal level
  • There are sophisticated fans that use a liquid to pass through the heat sink. This lets the heat move away from the system and the CPU cools down.
  • Dual fan application with exhaust fan can bring in cool air and carry away the hot air from the interiors.

These methods require external systems to be installed to reduce the temperature. However, we have simpler methods that you can follow on a regular routine.

  • Work from a well ventilated place so that there is some natural flow of cool air into the system and see that the exhaust fan is placed in the right direction to take the hot air out.
  • Spend some time every week to clean the system inside thoroughly. Accumulated dust can get filled in the air flow slots. Try to blow some compressed air into the system to clear of the dirt completely.
  • Undervolting is a method by which we can lower the excessive voltage provided to the CPU. This is one of the most recommended solutions in the recent past. It requires expert knowledge and the necessary software downloads to execute the procedure.

Maintaining the GPU and CPU temperatures are crucial for energy and power sustenance within the system. Consistent performance can increase the lifespan of the computer parts. Ensure you follow these methods regularly. This can enhance the system performance as a blessing in disguise..!!
