My Gpu Fan Curve Is Being Overridden When I Game – How To Fix It!
Your GPU fan curve may reset due to driver updates, software conflicts, power settings, or overclocking. Fix by using one control program and adjusting power settings.
In this article, we will explain why this happens, and more importantly, how you can fix it. We’ll break it down into simple steps and make sure it’s easy for you to understand, even if you’re new to PC gaming.
What is a GPU Fan Curve?
A GPU fan curve controls how the graphics card’s fan speed adjusts based on its temperature. As the GPU heats up during demanding tasks, the fan speeds up to maintain cooling. Using software like MSI Afterburner or EVGA Precision X, users can manually adjust the curve for optimal performance. A well-configured fan curve ensures efficient cooling and quieter operation, but issues arise when the curve is overridden or reset, potentially causing overheating or unnecessary noise during gaming.
Why is My GPU Fan Curve Being Overridden?
There are a few possible reasons why your GPU fan curve may be overridden or reset when you start playing a game. Here are the most common causes:
GPU Driver Updates or Changes:
GPU driver updates can reset fan settings to their defaults. When updating or installing new drivers, especially for Nvidia or AMD cards, custom fan curves might be overridden. Manufacturers often release driver updates that adjust various system settings, including fan control. If you’ve recently updated your drivers, check if your fan curve was reset to default settings, requiring manual reconfiguration through tuning software.
Third-Party Software Conflicts:
Running multiple GPU tuning software, such as MSI Afterburner, EVGA Precision X, or manufacturer-specific programs, can cause conflicts. These tools may interfere with each other, overriding custom fan curves. When more than one software manages fan speeds or GPU settings, they can unintentionally reset or conflict with your adjustments. Always ensure only one program controls fan settings to avoid issues and maintain the desired fan curve behavior.

Power Management Settings:
Windows power management settings and GPU control panels often override custom fan curves to optimize energy use. In gaming mode, your system may switch to higher performance settings, potentially interfering with fan control. This is more common in laptops but can affect desktops too. To fix this, adjust power settings in Windows or your GPU software to ensure that fan curves are not overridden by automatic energy-saving or performance modes during intensive tasks like gaming.
Automatic Fan Control by GPU Manufacturer:
Some graphics cards have built-in automatic fan control within their BIOS or firmware. These systems may override custom fan curves when the GPU is under load (e.g., during gaming) to protect the hardware from overheating. While this is designed to maintain optimal temperatures, it can interfere with user-defined fan settings. If your fan curve is being ignored, it’s likely due to the GPU’s automatic cooling adjustments that kick in during heavy usage.
Overclocking Issues:
Overclocking can interfere with custom fan curves. If you’ve overclocked your GPU, certain overclocking profiles might conflict with fan speed settings. Tools like MSI Afterburner adjust clock speeds and voltages, and these changes can unintentionally override or disable your fan curve settings. Additionally, unstable overclock settings can cause system instability, leading to unexpected fan behavior. Ensure your overclock is stable and properly configured to prevent interference with your custom fan settings.
How to Fix Your GPU Fan Curve Issue:
Now that we’ve covered the main reasons for your GPU fan curve being overridden, let’s take a look at how you can fix this issue. Follow these simple steps to restore your custom fan curve settings and ensure your GPU stays cool while gaming.
Check for Driver Conflicts:
Ensure your GPU drivers are up-to-date, but be cautious—driver updates can reset your custom fan curve. To check for updates:
- Press Win + X and select Device Manager.
- Expand Display Adapters, right-click your GPU, and select Update Driver.
- If your fan curve resets after an update, roll back to an earlier driver:
- Right-click your GPU > Properties > Driver tab > Roll Back Driver.
- You can also uninstall and reinstall drivers using Display Driver Uninstaller (DDU).
Avoid Multiple Fan Control Software:
Using multiple programs to control your GPU fan can cause conflicts. To fix this:
- Uninstall or disable extra fan control software.
- If using MSI Afterburner, go to the Fan tab and set a custom curve.
- Disable automatic fan controls in tools like Nvidia Control Panel or AMD Radeon Software.
This ensures one program manages your fan speeds, preventing conflicts and restoring your custom settings.

Adjust Power Management Settings:
Windows power settings may limit fan speeds or override your fan curve. To fix this:
- Open Control Panel > Power Options.
- Select High Performance mode.
This ensures your GPU gets the full power it needs during gaming, preventing any automatic changes to fan speeds or your custom curve. Avoid Balanced or Power Saver modes, as they may restrict GPU performance and fan control, affecting your fan curve settings.
Disable Automatic Fan Control in the BIOS:
Some GPUs automatically adjust fan speeds through their BIOS or firmware. To prevent this:
- Look for an option in your GPU BIOS to disable automatic fan control (check your manual or GPU’s website).
- If using software like MSI Afterburner, enable Force fan control to override default settings.
This ensures your custom fan curve is applied, and automatic adjustments are prevented, keeping your fan speeds in line with your preferences.
Recheck Overclocking Settings:
Overclocking your GPU can sometimes conflict with custom fan curves. To fix this:
- Open your overclocking software (e.g., MSI Afterburner) and reset the GPU to default settings.
- Gradually reapply overclock settings while testing stability after each change.
If the fan curve resets, adjust the curve settings within the overclocking software. Ensure your overclock is stable to prevent further interference with the fan speed settings.
Use GPU Manufacturer Software for Fan Control:
Sometimes using the built-in software from your GPU’s manufacturer (e.g., Nvidia Control Panel or AMD Radeon Software) may be more stable than third-party tools. To try this:
- Use the GPU manufacturer’s software to set your fan curve and fan speeds.
- These tools often provide simpler, more reliable control compared to third-party software like MSI Afterburner.
It may provide better results in maintaining your custom fan curve settings without issues.
Monitor Your GPU Temperatures:
Always track your GPU temperature to ensure it stays cool. Use software like HWMonitor or MSI Afterburner to monitor temperatures while gaming. If temperatures are high despite your fan curve settings:
- Adjust your fan curve to be more aggressive (higher speed at lower temperatures).
- Consider improving case airflow, adding more fans, or reapplying thermal paste.
This ensures your GPU stays cool and your fan curve settings effectively prevent overheating during intense gaming sessions.
FAQ’S
Why is my GPU fan curve being reset?
Driver updates, software conflicts, power management settings, or automatic cooling features may reset your custom GPU fan curve, affecting performance and cooling.
