How to Fix GPU Fans Not Spinning: Solve with Easy Steps

As a computer user or a gamer, one of the worst things that can happen is finding out that GPU fans not spinning. 

This issue can lead to overheating and potentially damage your graphics card. When I first encountered this problem, I immediately started troubleshooting to find the cause. 

In this article, I will share some common reasons why GPU fans may not be spinning and what you can do to fix them.

How to Fix GPU Fans Not Spinning

What are the Causes of GPU Fans not Spinning?

There are several reasons why GPU fans may not be spinning. Here are some of the most common causes:

1. Fan Control Settings: Some graphics cards have software that allows you to customize the fan speed. 

If the fan speed is too low, the fan may not spin. It is important to make sure that the fan control settings are set correctly.

2. Faulty Fan: GPU fans can break or wear out over time like any mechanical device. 

Anything obstructing your fan blades, such as dirt or dust, can cause the fan to stop spinning. Replacing the fan is usually the best course of action in this case.

3. Loose or Damaged Fan Connector: A connector connects the GPU fan to the graphics card. 

If this connector is loose or damaged, it can prevent the fan from spinning properly.

4. Overheating: When the GPU reaches a certain temperature, the fans spin faster to cool it down. 

If the GPU is overheating, it may be unable to spin the fans fast enough to cool itself down, resulting in the fans not spinning.

5. Power Supply Issues: If the graphics card is not getting enough power from the power supply, it may be unable to spin the fans. 

This happens when the fan is connected to the wrong power supply or the power supply needs to provide more wattage. 

6. BIOS Settings: Some graphics cards have BIOS settings controlling fan speed. 

If these settings are not configured correctly or if they have been changed accidentally, it can result in the GPU fans not spinning.

Methods to Fix GPU Fans Not Spinning

If the fans are not working correctly, your GPU can overheat and lead to performance issues or even hardware damage. If you face an issue like this, you should  try the following methods to solve the issue:

1. Check Your Drivers

Checking your drivers should be your first step. Outdated or corrupted drivers can cause the fans to stop working.

Here are some methods to fix GPU fans not spinning by checking your drivers:

Update your GPU drivers: Navigate to the manufacturer’s website and download the latest drivers for your GPU. 

Install them and restart your system. Check if the fans are working correctly.

Reinstall the drivers: If updating them does not solve the problem, try reinstalling them. 

You need to uninstall your system’s current drivers, restart your computer, and install the latest ones again.

Use Device Manager: You can use Device Manager to check for any issues with your GPU drivers. Right-click on the Windows button and select Device Manager. 

Locate your GPU, right-click on it, and select Properties. Under the Driver tab, select Update Driver and follow the on-screen instructions.

Check the BIOS: The issue could be related to the BIOS settings. Restart your computer and enter the BIOS setup. 

Look for any options that relate to GPU fans and make sure to enable them.

Following these methods, you can fix the GPU fans not spinning issue caused by outdated or missing drivers.

2. Stress Testing

Stress testing your GPU is a great way to fix GPU fans that are not spinning. 

It can help identify any issues with the fan and allow you to take corrective action before it becomes a major problem. Here’s how to do it:

i. Download a stress-testing program such as FurMark or MSI Kombustor. These programs will put your GPU under heavy load, allowing you to monitor its performance and detect any issues with the fan.

ii. Run the program for at least 30 minutes until you see signs of instability in the fan speed or temperature readings. 

If the fan speed drops below a certain threshold or the temperature rises too high, this could indicate an issue with the fan itself.

iii. If you notice any problems during the stress test, try to adjust your GPU settings, such as clock speeds and voltage levels, to see if this helps stabilize the fan speed and temperature readings.

It’s important to note that stress testing can be demanding on your GPU, so monitor the temperature and stop the test if it exceeds safe levels. 

Additionally, if the GPU is still under warranty, attempting to fix it yourself may void the warranty, so consider contacting the manufacturer first.

3. Restart Your PC

Restarting your PC is a simple yet effective method to fix GPU fans not spinning. 

It can help resolve any software-related issues that may be causing the fan to stop working. Here’s how to do it:

  • Close all applications and programs, then click on the Start menu in the lower-left corner of your screen.
  • Select the Power button from your window power options and choose Restart from the drop-down menu.
  • Depending on your hardware configuration, your computer will restart, which should take a few minutes.
  • Once your computer has restarted, check if the GPU fan is spinning again.

It’s important to note that some graphics cards won’t spin until your GPU temperature reaches a certain level; they come with a passive cooling mode that keeps them from spinning until necessary.

If so, you must increase your GPU temperature before attempting these fixes.

4. Check Power Connectors

Connectors are the one that connects your GPU fan to the power. If GPU fans are not spinning, ensure all the necessary power connectors are plugged in. 

To fix this issue, follow these steps:

i. Shut down your computer and unplug it from the power source to avoid electrocution or damage to the components.

ii. Open the computer case and locate the GPU. It is usually located in the PCI-E slot on the motherboard and has a power connector.

iii. Check if the power connector is properly seated in the GPU. If it’s loose, remove it and reseat it properly. Make sure it’s pushed in all the way.

iv. Check the power cable from the PSU (Power Supply Unit) to the GPU. Ensure it’s firmly connected to the GPU and the PSU.

v. If the power connectors are properly connected, but the fans are still not spinning, try using a different cable or connector. Sometimes the cable or connector may be damaged or faulty.

vi. Turn on your computer and check if the GPU fans are spinning.

It is important to ensure all power connectors are correctly plugged in, as this can cause serious damage to your graphics card if left unchecked for a long time.

5. Dusty Fan

Dust accumulation can prevent the fans from spinning, which can cause overheating and damage to the GPU. It is important to clean the fan regularly to ensure it runs properly. 

Here are some steps you can take to fix a dusty GPU fan:

i. Turn off your computer and unplug it from the power source.

ii. Open the computer case and locate the GPU. It is usually located in the PCI-E slot on the motherboard and has a fan on top of it.

iii. Use a can of compressed air to blow away the dust from the GPU fans. Hold the can upright and use short bursts of air to avoid damaging the fans.

iv. If the dust is stuck to the fans, you can use a soft-bristled brush to clean them gently. Be careful not to apply too much pressure, or you may damage the fans.

v. After removing the dust, close the computer case and plug it back in.

In summary, cleaning the GPU fans is an effective method to fix GPU fans not spinning.

Regularly cleaning your GPU fans can improve their performance and increase the lifespan of your GPU.

6. Oil the Fan Bearings

Sometimes, you need to open up the fan and lubricate its bearing with a few drops of oil. Using specialized fan oils can help reduce friction in this issue. Here are the steps you should follow:

i. Turn off the computer and unplug it from the power source.

ii. Open the computer case and locate the GPU.

iii. Carefully remove the GPU from its slot and detach the fan or fans from it.

iv. Use a cotton swab or a toothpick to remove dust or debris from the fan blades and surrounding area.

v. Apply a small amount of oil to the fan bearings. You can use machine oil, sewing machine oil, or light oil. Avoid using heavy oils or WD-40, as they can damage the bearings.

vi. Gently spin the fan blades to distribute the oil evenly.

vii. Reattach the fan or fans to the GPU and secure them.

viii. Reinstall the GPU into its slot and close the computer case.
