Are your GPU fans not spinning properly? This can cause overheating or lower performance, but don’t worry. I’ll walk you through why it happens and how to fix it.
Why Aren’t My GPU Fans Spinning?
GPU fans only spin when needed. If they’re not spinning, it might be because of:
| Cause | What It Means |
|---|---|
| Low Temperature | Fans don’t spin if the GPU isn’t hot enough. |
| Dust or Dirt | Dust can block the fans from moving. |
| Wrong Fan Settings | Software settings might be stopping the fans. |
| Driver Problems | Outdated or broken drivers can stop fan control. |
| Hardware Issues | The fan itself or its connection might be damaged. |
How to Fix GPU Fans Not Spinning
1. Check the Temperature
Fans often stay off when the GPU isn’t hot. Use tools like HWMonitor or MSI Afterburner to check the temperature. If it’s under 50°C, the fans might not need to spin.
2. Clean the Fans
Dust can stop fans from spinning. Here’s how to clean them:
- Turn off your computer and unplug it.
- Use compressed air to blow out dust.
- Wipe the fan blades gently with a soft cloth if needed.
3. Adjust Fan Settings
Wrong fan settings can cause issues. Follow these steps:
- Open your GPU’s software (like NVIDIA Control Panel or AMD Adrenalin).
- Go to the fan settings or performance tab.
- Adjust the fan curve to ensure the fans spin when needed.
4. Update Your Drivers
Outdated drivers can cause fan problems. To update:
- Visit your GPU’s website (NVIDIA or AMD).
- Download and install the latest drivers.
- Restart your computer.
5. Test the Fans
You can test the fans with software like MSI Afterburner. Set the fan speed manually to see if they work. If they don’t spin, there might be a hardware problem.
6. Check for Hardware Damage
If nothing else works:
- Make sure the fan connections are secure.
- Test the fans on another computer if you can.
- Replace the fans if they’re broken or contact the manufacturer for help.
