GPU Fans Not Spinning? 5 Ways to Fix It

Your graphics card is a critical component of your computer, and its cooling fan ensures the GPU operates at safe temperatures. If your GPU fan suddenly stops spinning, it can lead to overheating, performance throttling, or even system crashes. Don't panic—here's a practical guide to diagnose and resolve the issue.

1. Check for "Zero RPM" Mode

Many modern GPUs (including NVIDIA and AMD models) feature an intelligent fan stop function. This means the fans stay off during low workloads or cool temperatures to reduce noise and extend fan lifespan. If your fan isn't spinning at idle, this might be intentional.

How to test:

Launch a graphics-intensive game or stress-testing tool to heat up the GPU. If the fan starts spinning once temperatures rise (typically above 50°C), the zero-RPM mode is working as designed.

Use monitoring software (e.g., Driver Sentry) to track GPU temps. If temps climb but the fan still doesn't spin, proceed to the next steps.

2. Update or Reinstall Graphics Drivers

Outdated or corrupted drivers can disrupt fan control. This is especially common after driver updates or system upgrades.

How to fix:

Use a driver management tool (e.g., Driver Sentry) to scan for outdated drivers.

Download

Click "Scan" and check if your GPU driver is flagged. If so, select "Upgrade" and restart your PC.

If the issue persists, uninstall the driver completely via the tool's "Uninstall" feature, then reinstall the latest version.

3. Verify Power Connections

Loose cables or insufficient power delivery can prevent fans from spinning.

Steps:

Shut down your PC and unplug the power cable.

Check that the GPU's power connectors (6-pin/8-pin) are securely plugged into both the card and the power supply (PSU).

Ensure your PSU meets the GPU's power requirements. Low-wattage PSUs (e.g., under 400W) may struggle to power high-end cards.

4. Clean Dust or Debris

Dust buildup can jam fans or slow them down. If you hear grinding noises or see shaky movement, debris is likely the culprit.

Cleaning tips:

Use compressed air (hold fans still to avoid overspinning) or a soft brush to remove dust.

For stubborn grime, gently wipe fan blades with a microfiber cloth dipped in isopropyl alcohol.

Apply a drop of lubricant (e.g., WD-40) to the fan bearing if friction persists.

5. Test for Hardware Failure

If all else fails, the fan itself may be faulty.

Diagnosis:

Use GPU monitoring software to check fan speed readings. A constant "0 RPM" indicates a dead fan.

If under warranty, contact the manufacturer for repair/replacement. For older cards, consider installing an aftermarket cooler.

Most fan issues stem from software glitches, dust, or loose cables—not permanent hardware damage. Regularly clean your GPU, maintain updated drivers, and ensure proper airflow in your PC case. By following these steps, you'll likely restore normal fan operation and keep your GPU running smoothly!
