Troubleshooting GPU Fans Not Spinning – A Comprehensive Guide

You must diagnose and solve the issue if your GPU fans are not spinning. It is essential to determine the cause of your GPU Fans Not Working before taking further steps. Common causes of this problem include dirty fan blades, poor power delivery, worn-out bearings, and a clogged air filter. To diagnose the issue, you can check if the fan blade is blocked or obstructed and if it has enough power. If none of these problems exists, it could be because of a worn-out bearing or a clogged air filter. In this case, you will need to replace them with new components. Once you have identified the cause, you can take the necessary steps to fix the GPU fan that isn’t spinning. With proper troubleshooting and maintenance, you can ensure that your GPU fans are running smoothly and efficiently.

Introduction to GPU Fans

A Graphics Processing Unit (GPU) is a crucial computer component. It is responsible for processing visuals and graphics, making gaming and video editing essential. GPUs are typically quite powerful and generate a lot of heat, which is why they are usually equipped with fans for cooling. These fans are crucial for keeping the GPU at an optimum temperature and ensuring it works properly. However, sometimes these fans may stop spinning, which can cause the GPU to overheat and even damage the components. This blog post will discuss the common causes of GPU fans not working and how you can troubleshoot the issue.

Common Causes of GPU Fans Not Spinning

There are several possible reasons why your GPU fan might not be spinning. The most common causes include the following:

  • A faulty power supply
  • GPU overloading
  • Poor connections between the GPU and the power supply
  • A faulty fan connector
  • Excessive heat on the GPU
  • Low RPMs on the fan

Troubleshooting Steps

If your fans won’t start spinning, the first step is to troubleshoot the issue. Here are some steps you can take to diagnose and fix the problem:

Check the Power Supply

The first step is to ensure the power supply is connected correctly and delivers the appropriate voltage. You can use a multimeter to check the voltage and ensure it falls within the recommended range. If you find the power supply is not working correctly, you should consider replacing it as soon as possible. Failing to have the correct power supply will often result in issues with your GPU fans not spinning. A quality power supply will help keep your GPU running correctly and extend its lifespan. Therefore, checking your power supply and ensuring its function is mandatory before taking further action.

GPU overloading

Before proceeding any further, ensuring that your GPU fans are functioning well is vital. It is common for GPU fans to only spin if the card is under load and the temperature reaches a specific level, as this is an efficient way to save energy. To test this, restart your computer and watch to see if the GPU fans are spinning. Additionally, you can test the functionality of your GPU fans by running a game or rendering an image on the system, as this will put the card under load and cause the fans to spin as needed. This method should give you a good indication of whether or not your GPU fans are working correctly.

The first step to troubleshooting your GPU fan is to restart your computer. On boot, it is normal for all the fans to spin briefly at full speed to check they are working if your GPU fan is not spinning, which is a sign that has an issue. 

At last, make a stress test on your GPU using a utility. As the test runs, the GPU will generate heat and your fans should start spinning accordingly. It is essential to watch for this, as it could otherwise lead to your GPU overheating. If you do not see the fans spinning, kill the test immediately and investigate further the issue with your GPU.

Clean the GPU

 If your GPU’s fans are not spinning, they may be blocked by debris. To check, power off the computer and turn the fans with your finger to see if they spin freely. If they don’t, you should clean inside the CPU with compressed air to remove dirt and dust. Be gentle when cleaning the GPU fans, as they are fragile and easily damaged. Failing to take proper care of your GPU fans can result in poor cooling performance and decreased lifespan, so it’s vital to ensure that your graphics card’s fans are always working correctly.

Check the Card’s Connectors

Check the Card's Connectors

After ensuring that the connectors on the GPU are correctly connected, it is vital to check the fans. The fans should spin if all the cables are securely connected, and there are no bent or damaged pins. It is vital to ensure the cables are not loose, which might prevent the fan from spinning. Therefore, inspecting the connectors should resolve any issue with the GPU’s fans that don’t spin. Furthermore, replacing any bent or damaged pins may be necessary to ensure a proper connection and facilitate regular fan operation.

Check the Fan’s Connector

Another common issue to consider while finding your GPUs do not allow their fans to start spinning is a faulty fan connector. Ensure a secure connection between the fan and the card and no loose wires. Additionally, look closely at the fan’s connector for any signs of damage or corrosion. If the connector appears faulty, it may be necessary to replace it. In this case, contact a professional to ensure the replacement is done correctly and safely. Remember that it is crucial to address this issue quickly, as failing to do so could cause serious harm to your GPU.

Check the Card’s Temperature

The next step would be to check the temperature of the GPU. If the card is overheating, likely, the fans may not spin. As such, it is essential to use a software program to monitor the temperature of the GPU and keep it within the recommended range. If the GPU is overheating, you should adjust the fan settings or consider replacing the cooling system altogether. It will ensure that the fans are spinning to maintain a proper temperature for your GPU. Additionally, if your GPU fans are not spinning, it could indicate a more severe problem with your cooling system, and it’s important to have it addressed as soon as possible.

GPU Fans Not Spinning: Check the Fan’s RPM

The final step in ensuring the GPU fans are working is to check their RPM (Revolutions Per Minute). If the fan does not spin at the recommended speed, it may not be able to cool the GPU effectively. A software program can monitor the fan’s RPM and ensure it is within the acceptable range. If the fan’s RPM is too low, you may need to adjust its settings or replace it entirely. It is important to take the time to properly check the GPU fans as they are responsible for ensuring your system runs at optimal temperatures and performance. If your GPU fans still don’t spin as they should, take the necessary steps to ensure they are operating correctly.

Replacing the GPU Fan

If all of the above steps fail to fix the issue of your GPU fans that aren’t spinning, you will likely need to replace the fan. Ensure that you buy a fan compatible with your GPU and carefully follow the instructions provided by the manufacturer for installation. It is essential to take all necessary safety precautions when carrying out the installation and handling of components. After replacing the fan, you should be able to get your GPU working properly again. You can also seek a professional technician’s help for installation as they are more experienced and knowledgeable in this area. All in all, by replacing the GPU fan, your system should be able to run normally again.


If your GPU fan isn’t spinning, it can cause your card to overheat and damage the components. In this blog post, we discussed the common causes of GPU fans not spinning and provided detailed troubleshooting steps that you can use to diagnose and fix the issue. If all else fails, you may need to replace the GPU fan. We hope this guide has been helpful and you can now get your GPU working correctly again.
