 GPU Fans Don’t Spin: Common Reasons and their possible Solutions

Dust Buildup

Dust buildup in graphics cards can negatively impact their performance and longevity. Dust can clog the cooling fans, causing overheating and potentially damaging components. It can also interfere with airflow and heat dissipation, leading to overheating.


To prevent dust buildup, it is recommended to clean the graphics card and its surrounding components regularly, at least once every month. This can be done using compressed air or a soft brush to remove loose dust and debris.

Follow the proper procedures when cleaning graphics cards to prevent damage. Make sure to shut down the PC, disconnect any power sources, and remove the graphics card before cleaning it. Do not touch the components or circuits with your hands, as oils from your skin can cause corrosion.

A good airflow and dust filter case can also help prevent dust buildup in your PC components. Regularly cleaning the dust filters and maintaining good airflow in the case can help prevent dust from accumulating on the graphics card.

Power Issue

A power issue in a graphics card can cause the fans not to spin, which can result in overheating and potentially damage the GPU.

Possible causes of power issues include:

Insufficient power supply: The GPU may not receive enough power from the power supply unit (PSU).

Damaged power cables: A damaged cable connecting the PSU to the GPU can prevent power from reaching the GPU.

Loose power connectors: Loose power connectors between the GPU and the PSU can prevent the GPU from receiving power.


To fix power issues in a graphics card, you can try the following steps:

  • Ensure your power supply unit (PSU) has enough wattage to support the graphics card.
  • Check the power cables between the graphics card and the PSU to ensure they are securely connected.
  • Ensure the graphics card is seated correctly in the PCIe slot.
  • Update the graphics card drivers and BIOS to the latest version.
  • Check for any physical damage on the graphics card or power connectors.
  • Try running the graphics card on a different system to determine if the issue is with the card or the method.
  •  If the problem persists, consider replacing the graphics card.
  •  If you need to familiarize yourself with these steps, you should consult a professional or manufacturer for further assistance.

Driver Issue

Outdated or incorrect GPU drivers can cause the fans not to work correctly.

Driver issues in graphics cards can cause a variety of problems, including:

  • Performance issues
  • Visual artifacts or glitches
  • Crashes or freezes
  •  Incompatibility with software or games


You can update the driver to the latest version or roll back to an earlier version to resolve driver issues. You can also try uninstalling and reinstalling the driver or disabling features such as overclocking to see if that helps. If the problem persists, consider contacting the manufacturer for further assistance.

Hardware Issue

A damaged fan or fan controller can prevent the fans from spinning.

Hardware issues in a computer can cause a variety of problems, including:

  •  Performance degradation
  • Blue screen of death (BSOD) errors
  • System crashes or freezes
  • No power or turning off randomly
  • Strange noises or smell


If you suspect a hardware issue, try restarting the computer and checking if the problem persists. You can troubleshoot specific components such as the hard drive, RAM, or graphics card if it does. In some cases, you may need to replace the damaged part. If you need help with how to diagnose the problem, consider seeking assistance from a professional technician.


If the GPU is overheating, the fans may not spin fast enough to cool it down.

Overheating in graphics cards can be caused by the following:

  • Poor ventilation/airflow within the computer case
  • Dust buildup on the cooling fan and heatsink
  •  High ambient temperature
  • Overclocking
  • The power supply unit is not providing enough power


  • To resolve overheating issues, try the following:
  •  Cleaning the computer
  • Improving ventilation/airflow
  • Lowering graphics card clock speed or voltage
  • Replacing the old thermal paste with the high-quality thermal pads
  • Upgrading the power supply unit.

Fan Speed Set too Low

Setting the fan speed too low on a graphics card can cause the card to overheat, leading to reduced performance and potentially damaging the hardware. Graphics cards generate a lot of heat while performing demanding tasks, and without adequate cooling, the internal temperature can reach dangerous levels. A low fan speed can result in the fan being unable to dissipate the heat, causing the temperature to rise effectively.


To avoid this, you can increase the fan speed or adjust the fan curve in the graphics card software. Many graphics card manufacturers provide software that allows you to monitor and control the fan speed. You can change the fan curve so that the fan speed increases as the temperature rises, ensuring that your graphics card stays cool even under heavy loads.

Additionally, ensuring adequate airflow in your computer case can help keep your graphics card cool. Dust can accumulate in the fans and other components, reducing their effectiveness. Regular cleaning of the fans and other components can improve airflow and prevent dust buildup.

Ensure the graphics card is seated correctly and securely in the PCIe slot. A loose card can also cause overheating as the fans may not be able to spin as freely.

Interference from Wires or Something Else

Interference in graphics cards can be caused by several factors, including:

  • Electromagnetic Interference (EMI) from nearby wires or electronic devices
  •  Radio Frequency Interference (RFI) from other wireless devices
  • Power supply noise
  • Poor shielding in the graphics card or computer case


To reduce interference, you can try the following:

  • Keep the graphics card and its cables away from other electronic devices.
  • Use ferrite bead or EMI filters on the cables connected to the graphics card.
  • Use a high-quality, stable power supply.
  • Ensure proper grounding and shielding for the computer case and graphics card.

Bad or Buggy GPU Fan Curve

A bad or buggy GPU fan curve can cause various issues that can negatively impact the performance and longevity of a graphics card. The GPU fan curve controls the fan speed that cools the graphics processing unit (GPU), and it is crucial to set it correctly to ensure proper cooling and prevent overheating.

Issues Caused By a Bad GPU Fan Curve Can Include:

Noise: If the fan speed is set too high, the GPU fan can become excessively loud, frustrating users.

Inefficient Cooling: If the fan curve is not set optimally, the GPU may not be adequately cooled, even if the fan runs at full speed.


To avoid these issues, setting the GPU fan curve correctly is essential. Many online resources provide guidelines for setting the fan curve optimally for different GPU models.

A bad or buggy GPU fan curve can cause several problems that can affect the performance and lifespan of a graphics card. To avoid these issues, it is essential to set the fan curve correctly through the graphics card’s control panel or software.

Can My GPU Fans Spin All the Time? 

Yes, GPU fans can spin all the time. GPU fans are designed to turn whenever the GPU temperature exceeds a certain threshold, which the manufacturer sets. The GPUs usually regulate the fan speed. GPU’s built-in temperature sensors and fan control software. If the GPU runs hot, the fans spin faster to dissipate the heat. If the GPU is running cool, the fans will spin more slowly or not at all.

It is essential to keep your GPU cool to ensure its proper function and longevity. Running the fans all the time can help prevent overheating and prolong your GPU’s lifespan. However, it is also possible for the fans to spin all the time, even if the GPU is not overheating. This can be caused by a malfunctioning temperature sensor or fan control software. If this happens, try troubleshooting the issue by updating the GPU’s drivers or reinstalling the fan control software.

GPU fans can spin all the time, and doing so can help keep your GPU cool and prevent overheating. However, if your fans are turning all the time and the GPU is not overheating, there may be a problem that needs to be addressed.


There’s a good possibility something is wrong if you’ve just noticed your GPU fans are not spinning even while the system is under pressure.You have a big issue if you’ve noticed that your GPU is overheating. 

In this detailed guide, we have explained the root issues of graphics card fans not spinning and also their quick and easy solutions. After reading it thoroughly, you can resolve all these issues without any prior technical knowledge.
