GPU Fans Not Spinning – How To Fix?

Here's a step-by-step guide to help you diagnose and fix the problem.

A GPU (Graphics Processing Unit) fan not spinning can lead to overheating and potentially damage your graphics card. It’s essential to address this issue promptly. Here’s a step-by-step guide to help you diagnose and fix the problem.

1 Check for Visible Obstructions:

Step 1: Turn Off Your Computer Ensure your computer is completely powered off, and unplug it from the electrical outlet to ensure your safety during the process.

Step 2: Open Your PC Case Carefully open your computer case or side panel to access the internal components. This typically involves removing a few screws or using latches, depending on your computer case design.

Step 3: Locate the GPU Identify your GPU, which is the graphics card installed in one of the PCIe slots on your motherboard. It’s usually easy to spot, as it’s a dedicated card with video outputs and a fan or fans.

Step 4: Visually Inspect the GPU Fan Look closely at the GPU fan. Check for any visible obstructions such as dust, cables, or foreign objects that may be blocking the fan’s movement. Also, check the area around the fan to ensure nothing is interfering with its rotation.

Step 5: Remove Obstructions If you spot any obstructions, gently remove them. Use compressed air to blow out dust and debris from the fan and surrounding components. Make sure you clean the entire graphics card as dust can accumulate in various areas.

Step 6: Close Your PC Case After ensuring that there are no obstructions and cleaning any dust, securely close your PC case or side panel.

Step 7: Reconnect and Power On Reconnect any cables you may have disconnected during the process, including the power cable, monitor, keyboard, and mouse. Then, plug your computer back into the power source.

Step 8: Power On Your Computer Start your computer and check if the GPU fan starts spinning. You can run a GPU monitoring tool to observe the fan’s operation and monitor the GPU temperature.

If the fan starts spinning after clearing obstructions and cleaning, your issue is likely resolved. If the problem persists, you may need to explore other potential causes, such as loose cables, driver issues, or fan failure.

2. Clean the GPU and Fan:

  • If there’s dust buildup, use compressed air to gently blow out the dust from the fan and surrounding components.
  • Clean the entire graphics card while you’re at it to ensure optimal airflow.

3. Check the Fan Connection:

  • Ensure that the fan’s power cable is securely connected to the GPU. Re-seat the cable if necessary.

4. Update GPU Drivers:

  • Outdated or corrupted GPU drivers can sometimes cause fan issues. Download and install the latest drivers from the GPU manufacturer’s website.

5. Monitor GPU Temperature:

  • Install a GPU monitoring tool like MSI Afterburner or HWMonitor to keep an eye on the GPU temperature.
  • Run a demanding application or game to stress the GPU, and check if the temperature rises significantly.

6. Test the Fan Manually:

  • In some cases, the GPU fan may not start spinning until a certain temperature is reached. You can manually set the fan speed using tools like MSI Afterburner or the GPU control software provided by the manufacturer.

7. Check for Fan Failure:

  • If cleaning and checking connections didn’t work, it’s possible the fan has failed. You may need to replace the fan.
  • Contact the GPU manufacturer or a qualified technician to order a replacement fan or assess whether a complete GPU replacement is needed.

8. BIOS/UEFI Settings:

  • Some motherboards offer fan control settings in the BIOS/UEFI. Ensure that these settings are configured correctly.

9. External Factors:

  • Ensure that your GPU isn’t obstructed by other components or cables in the case, hindering airflow.
  • Check your PC’s overall cooling to make sure it’s adequate.

10. Backup and Data:

  • Before making any major changes, back up your data to prevent data loss in case of unexpected issues during GPU replacement.

11. Seek Professional Help:

  • If you’re uncomfortable working with hardware or if the GPU fan problem persists, consider taking your PC to a professional technician for diagnosis and repair.

Frequently Asked Questions (FAQs)

Q: Why is my GPU fan not spinning?

A: There can be several reasons for a GPU fan not spinning, including dust accumulation, loose cables, driver issues, fan failure, or BIOS/UEFI settings. It’s essential to determine the specific cause to apply the appropriate solution.

Q: How can I quickly diagnose a GPU fan issue?

A: Begin by visually inspecting the GPU for any obstructions, loose cables, or visible dust. This can help identify some common quick-fix solutions.

Q: What should I do if I see dust or debris on the GPU fan?

A: Use compressed air to gently blow out the dust and debris from the fan and surrounding components. Regular cleaning can help maintain proper airflow.

Q: What if the fan cable is loose or disconnected?

A: Reconnect the fan cable securely to the GPU. A loose connection can often cause the fan to stop working.

Q: How do I update GPU drivers to fix the fan issue?

A: Visit the GPU manufacturer’s website and download the latest drivers for your GPU model. Install them, and it may resolve any driver-related problems causing the fan to stop spinning.

Q: Can I manually test the GPU fan?
