The GPU fan is a crucial component for keeping your graphics card cool. If you notice that your GPU fan has suddenly stopped spinning or won't start, it could lead to overheating, performance drops, or even permanent damage. This article provides a systematic troubleshooting guide to help you quickly resolve the issue.

Step 1: Basic Checks to Rule Out Simple Issues

1. Confirm Whether the Fan Is Actually Not Spinning

Observing the Behavior: Some graphics cards support a "zero RPM mode", where the fan stops spinning under low loads. Try running a high-load task (such as a game) and see if the fan starts up.

Using Monitoring Tools: Software tools can display real-time fan speed. If the reading is 0 RPM and the GPU temperature continues to rise, the fan control may not be working properly due to a driver issue.

2. Check Power Connections

External Power Supply: High-end GPUs require a 6-pin or 8-pin power connector. Make sure the cable is securely connected and not loose.

Insufficient Power Supply: A low-quality or underpowered PSU (Power Supply Unit) can cause unstable power delivery. Try testing with a higher-wattage PSU if necessary.

Step 2: Software and Firmware Fixes

1. Check and Fix Driver Issues

Corrupt or Incompatible Drivers: A faulty or outdated GPU driver can interfere with fan control. You can use Driver Sentry to scan and fix driver issues automatically, ensuring you get the latest official and stable version instead of downloading the wrong driver manually.

Disable Overclocking Software: Some overclocking tools override default fan settings. Uninstall any third-party overclocking software and use Driver Sentry to reinstall the official drivers, restoring the original fan control settings.

2. Check BIOS and Firmware Settings

BIOS Configuration: Enter your motherboard's BIOS and navigate to the Hardware Monitor section to ensure the fan control feature is enabled.

Step 3: Hardware Fixes

1. Clean Dust and Remove Obstructions

Steps:

1. Shut down your PC and disconnect the power.

2. Remove the graphics card from the system.

3. Use compressed air to clean the fan blades, heatsink, and PCB.

4. Check if the fan bearings are obstructed by wires or other debris.

2. Secure the Power Connectors

The fan stops spinning after cleaning or moving the PC.

Fix:

1. Turn off the PC and unplug it.

2. Locate the 4-pin or 6-pin power connector on the side of the GPU.

3. Unplug and reconnect it firmly (you should hear a "click" sound).

4. If the issue persists, try using a different PCIe power cable in case the original one is faulty.

While a non-spinning GPU fan can be frustrating, it is often fixable using the steps outlined above. Additionally, it's a good idea to regularly check for driver updates using Driver Sentry to ensure smooth performance and prevent future issues.
