Have you ever noticed your graphics card (GPU) overheating during gaming or resource-intensive applications? If so, you're not alone. Many GPU users report their cards overheating, which can lead to reduced performance, visual artifacts, and even hardware damage.
Fortunately, there's a way to control your GPU's temperature and improve its performance: by adjusting the fan curve. A fan curve is a feature that controls the speed of your GPU's fans based on its temperature. By adjusting the fan curve, you can make your fans spin faster when your GPU gets hot, allowing for more efficient cooling.
What is a fan curve?
A fan curve is a graphical representation of your GPU's fan operation. It shows how the fan speed varies with the GPU's temperature. In other words, the higher the GPU temperature, the higher the fan speed will be to keep the GPU cool.
Imagine the fan curve as a graph with the horizontal axis representing the GPU temperature and the vertical axis representing the fan speed. The curve connects the points corresponding to different temperatures and fan speeds. For example, at a temperature of 20°C, the fan speed might be 30%, while at a temperature of 45°C, the fan speed might be 40%. The fan curve allows the system to automatically regulate the fan speed based on the GPU temperature.
The curve of your original GPU fan is probably zero
It's important to understand that GPU manufacturers generally focus on fan curves that ensure quiet operation right out of the box. This means that even when your GPU reaches high temperatures, the fans won't be running at their maximum speed. Manufacturers prioritize quiet operation over cooling performance.
However, this can lead to overheating, performance drops, and even long-term GPU degradation. When your GPU reaches high temperatures, it may reduce its clock speed to prevent overheating. This results in decreased performance and a less smooth gaming experience.
How to adjust your GPU fan curve for better performance
Programs for adjusting the fan curve
Several programs allow you to adjust your GPU's fan curve. Among the most popular are AMD Adrenalin for graphics cards and MSI Afterburner , which is compatible with all GPU brands and models. These programs offer advanced features for customizing the fan curve and optimizing your GPU's cooling.

Use MSI Afterburner to adjust the fan curve
To adjust your GPU's fan curve with MSI Afterburner, you need to follow these steps:
- Download and install MSI Afterburner from the official website.
- Open the program and click on the gear icon to access the settings.
- In the " Fan " tab, check the box " Enable automatic fan control by user-defined software ".
- You will see a fan speed curve. By default, the Afterburner fan curve is different from your GPU's default fan speed curve. You can select the default Afterburner fan curve by viewing " Default " under " Predefined Fan Speed Curve ".
Customize the fan curve
The default fan curve in MSI Afterburner is already quite good and can offer improved cooling and performance compared to your GPU's original curve. However, if you want to further optimize your GPU's cooling, you can switch to a custom fan curve.
To create a custom fan curve in MSI Afterburner , follow these steps:
- Select " Custom " under " Preset Fan Speed Curve ".
- Manipulate the fan curve by dragging the nodes along the curve up, down, left, and right.
- You can add nodes by clicking anywhere on the curve and delete them by pressing the " Delete " key on your keyboard.
The exact fan curve you use will depend on your personal preferences and the specifications of your GPU. It's recommended to start with 0% speed at temperatures below 40°C, 100% speed at 85°C , and then adjust the rest of the fan curve accordingly. This keeps the GPU quiet during light tasks while ensuring it's effectively cooled during intensive gaming sessions.
Test and adjust the fan curve
Once you've created your custom fan curve, it's important to test it to find the right balance between fan noise and your GPU's cooling performance. Every GPU is different, with specific temperature ranges and cooling solutions, so there's no one-size-fits-all solution.
Here are some steps to test and adjust your fan curve:
- Perform a fan curve similar to the default one in MSI Afterburner .
- Launch a game or a GPU benchmark tool, such as 3DMark , to stress your GPU and increase its temperature.
- Monitor your GPU temperature during the gaming session or benchmark test.
- If the temperature exceeds your comfort limit or if you notice decreases or graphical artifacts, you will need to increase the fan speed.
- Repeat this process until you find the right balance between temperature and fan noise.
FAQs
1. Why do I need to adjust my GPU's fan curve?
Adjusting your GPU's fan curve can improve cooling performance. This can help maintain lower temperatures, prevent overheating, and enhance your GPU's performance.
2. How can I adjust the fan curve of my GPU?
You can adjust your GPU's fan curve using software such as Afterburner. This software allows you to create a custom fan curve in just a few clicks.
3. What is the default fan curve for my GPU?
Manufacturers typically use fan curves that ensure quiet operation right out of the box. This means that even when your GPU reaches high temperatures , the fans won't be running at their maximum speed.
4. How can I find the optimal fan curve for my GPU?
Every GPU is different, so it's important to check your GPU's specifications and run tests to find the fan curve that works best for your system. You can adjust the curve based on your preferences and your GPU's optimal temperatures.
5. Can adjusting my GPU fan curve damage my hardware?
If you follow the manufacturer's recommendations and adjust the fan curve appropriately , it shouldn't damage your hardware. However, it's important to monitor temperatures and run tests to ensure your GPU stays within safe temperature limits.
