[Graphics Card] Cooling – Troubleshooting Guide
The graphics card fan helps circulate air to maintain stable and safe operating temperatures inside the card. The fan speed will automatically adjust according to the GPU temperature. When running resource-intensive applications such as gaming, video editing, transcoding, or large-scale data processing, the GPU temperature rises and the fan accelerates to allow more cool air through the cooling system. This may result in louder fan noise.
If airflow is blocked by dust, hair, or other debris in the vents or fan, your graphics card may overheat, causing performance drops and high fan noise. Please refer to the following troubleshooting steps.
Common causes of graphics card overheating or fan issues:
• Abnormal programs consuming excessive CPU/GPU/memory resources
• Inadequate environment or ventilation
• Dust build-up inside the graphics card or at the exhaust vents
• Fan speed drops or wear due to prolonged use
How to resolve graphics card overheating:
Check for abnormal programs using Task Manager
When running demanding applications, it is normal for CPU/GPU/memory temperatures to rise, and for the fan to speed up. Task Manager in Windows helps you monitor running applications and processes, providing information on system resource usage.
Check Task Manager to see if any programs are using more CPU/GPU/memory than expected. If you find abnormal usage, end those processes. If the problem persists, proceed to the next troubleshooting step.
Inspect fan functionality and select an appropriate fan mode
1. Regularly inspect all graphics card fans to ensure they are not blocked by cables or other components and are operating normally.
2. Check if any fan is damaged, and confirm that the fans are spinning as expected.
a. If the fans are not spinning, first check if your graphics card is set to 0dB mode. Refer to the FAQ for details: Troubleshooting - Fan stops working when booting the device.
b. If the fans still do not spin, contact ASUS service center for fan or cooling module inspection and replacement.
3. For different workloads, you can use ASUS GPU Tweak III software to adjust fan modes, balancing performance and temperature. Refer to the official FAQ for GPU Tweak III settings.
Maintain proper ventilation for your graphics card
1. Ensure your PC case is well ventilated:
a. Place your PC case on a hard, flat surface (e.g., desk), and avoid putting it on soft surfaces, carpets, or in enclosed spaces.
b. Make sure there is sufficient space around the case and its ventilation openings (front panel, rear panel, top, and sides) to allow good airflow and ventilation, helping prevent overheating.
c. Check the internal fan setup. If airflow inside the case seems insufficient, consider adding more case fans.
d. Try opening the side panel of the case. If the graphics card temperature drops noticeably, continue troubleshooting using the following steps.
2. Prevent dust and debris build-up:
If your environment has a lot of dust, pet hair, or if you smoke, regularly clean the case, fans, and heatsinks. Refer to the FAQ on how to clean your graphics card for detailed instructions.
3. Avoid high temperature and humidity:
a. Do not use your computer in high-temperature or humid environments, such as under direct sunlight or near heat sources.
b. Try moving your case to a different environment or lowering the ambient temperature. If the issue is resolved, it may have been caused by high environmental temperature.
Check for overclocking
If you have overclocked your graphics card, it may cause overheating. Try restoring the default clock speeds and see if the temperature improves.
