Are you wondering how to control GPU fan speed to maintain optimal performance and prevent overheating? Managing your graphics card’s fan speed is crucial for keeping your system running smoothly, especially during intense gaming sessions or demanding tasks like video editing or 3D rendering. In this guide, we’ll explore simple yet effective methods to adjust your GPU fan speed, ensuring your hardware stays cool and performs at its best. Whether you’re a seasoned gamer or a newcomer to PC building, mastering GPU fan control is essential for maximizing your system’s efficiency and longevity.
Understanding GPU Fan Speed Control
Monitoring Fan Speed
To control your GPU fan speed, you first need to monitor it. Many GPUs come with built-in software to check things like fan speed, temperature, and clock speeds. If you have an NVIDIA card, utilize the NVIDIA Control Panel. For AMD cards, use the Radeon Software. These will show you your current fan speed and max speed.
Why Adjust Fan Speed?
You may want to increase your GPU fan speed for a few reasons:
- Your GPU is overheating while gaming or doing other intensive tasks. The fans need to spin faster to cool the card and prevent thermal throttling.
- Your GPU fans are not spinning fast enough on their own to properly cool the card. Some GPUs have more conservative fan profiles out of the box.
- You want to manually optimize the fan speed for the best balance of cooling and noise. Faster fans mean cooler temps but more noise.
- You’ve overclocked or modified your GPU and need extra cooling to compensate. Overclocking pushes your card harder, so it needs more airflow.
How to Control Fan Speed
The easiest way to control GPU fan speed is through the same software you used to monitor it. In the NVIDIA or Radeon control panels, you’ll find options to create custom fan profiles. This means you can set the fan speed to increase at certain temperature thresholds. You can also often directly set a static fan speed.
For example, you may want the fans to run at 30% at 50°C, 50% at 65°C, and 70% at 80°C. This ensures your GPU is cooled properly as the workload increases without the fans being too loud when idle. Play around with different profiles to find the right balance for your needs.
Checking Your Current GPU Fan Speed
To properly control your GPU fan speed, you first need to determine your current fan settings. There are a couple of ways to check your GPU fan speed:
Using GPU Monitoring Software
The easiest way is to use free GPU monitoring software like MSI Afterburner, EVGA Precision X1, or NZXT CAM. These tools allow you to view details about your graphics card like clock speed, temperature, fan speed, and more.
Checking in the BIOS
You can also check your GPU fan speed in your motherboard’s BIOS menu. Restart your PC and press the BIOS key (usually Delete, F2, or F12) to enter the BIOS. Navigate to the section for PC Health or Hardware Monitoring. There you should find the current fan speeds for all fans connected to your motherboard, including the GPU fans.
The fan speed will typically be displayed as an RPM reading here. Note that not all motherboards provide GPU fan speed info in the BIOS, so the monitoring software method may be needed.
Reading Fan Speed Sensors
As a last resort, you can try using a hardware fan speed sensor or tachometer to physically check the GPU fan RPM. These tools connect to the fan header or cable and display the real-time fan speed reading. However, this requires opening up your PC case and connecting the sensor, so software options are generally easier.
How to Control GPU Fan Speed? (Step-By-Step)
1. Download Manufacturer Software:
- NVIDIA: Visit the NVIDIA GeForce Experience website and download the latest version of GeForce Experience.
- AMD: Head over to the AMD Radeon Software website and download the appropriate software for your specific AMD graphics card.
2. Launch the Software:
- Once downloaded and installed, launch the manufacturer’s software (e.g., GeForce Experience for NVIDIA, Radeon Software for AMD).
3. Locate Fan Speed Controls:
The exact location of fan speed controls may vary slightly between manufacturers. Here’s a general guideline:
- NVIDIA: Within GeForce Experience, navigate to the “Settings” menu and look for the “Performance” or “Fan” section.
- AMD: In Radeon Software, explore the “Settings” or “Tuning” section for options related to fan control.
4. Adjust Fan Speed Settings:
The software might offer different control methods:
- Manual Mode: This allows you to set a fixed fan speed percentage. Use caution, as excessively low speeds can lead to overheating.
- Custom Fan Curve: This lets you define a fan speed curve based on GPU temperature. Lower temperatures will result in slower fan speeds, while hotter temperatures will trigger faster fan rotation for improved cooling.
5. Apply and Monitor:
- Once you’ve chosen your preferred fan control method, be sure to apply the changes within the software. It’s recommended to monitor your GPU temperature under load (e.g., while gaming) to ensure it stays within safe operating limits.

Adjusting GPU Fan Speed With Software
Controlling your GPU fan speed manually is actually pretty straightforward using free software utilities. The two most popular options are MSI Afterburner and EVGA Precision X1. Both work with graphics cards from all brands, not just MSI or EVGA.
1. MSI Afterburner
MSI Afterburner is a lightweight program that gives you real-time control over your GPU. You can use it to adjust the power limit, core clock, memory clock, and fan speed of your graphics card.
To adjust your fan speed, open MSI Afterburner and you’ll see sliders for controlling various settings. The slider for “Fan Speed(%)” is what you use to adjust how fast your fan spins. Drag the slider to the left to slow the fans down or to the right to speed them up. You’ll see the RPM reading change in real time as you adjust the slider.
2. EVGA Precision X1
EVGA Precision X1 is another software option for tweaking your GPU settings. The layout and options are very similar to MSI Afterburner. You’ll find a “Fan Speed Curve” graph, which allows you to set custom fan speeds at different temperature points.
For example, you can set the fans to run at 30% at 50°C, 50% at 70°C, and 100% at 90°C. This gives you complete custom control over your graphics card cooling based on the current temperature. You can also enable fan speed hysteresis to prevent rapid fan speed changes.
Using either Afterburner or Precision X1, you have full manual control over your GPU fan speed. Start by increasing your fan speed in 10% increments while running a graphics-intensive game or application.
Customizing Fan Curve for Optimal Cooling
To keep your graphics card running at optimal temperatures during intense gaming or other GPU-heavy tasks, you’ll want to adjust the fan speed. The default fan curve set by the card manufacturer may not be aggressive enough, which can lead to overheating and reduced performance. Creating a custom fan curve gives you full control over your GPU fans and ensures maximum cooling when you need it most.
Determine Maximum Fan Speed
Check your graphics card specs to find its maximum fan speed in RPM or percentage. You want to set your curve so the fans don’t exceed this limit, to avoid damage. For most cards, max speed will be between 70-100%. Start your curve at a slightly lower maximum, around 80-95% to be safe.
Set Control Points
A custom fan curve is made up of data points at certain temperatures that determine the fan speed. The most common approach is to have fans off below 60°C, then ramp up aggressively as the temperature increases. For example, set 60°C at 30% fan speed, 70°C at 50%, 80°C at 70%, and your maximum speed at 85°C or above. The curve should steadily increase between these points.
Test and Tweak
Save your custom curve and put your GPU under load to test the new fan speeds. Check that temperatures level off at the higher fan speeds you set. If it’s still running too hot, you may need to increase the curve’s maximum speed or add additional control points at higher temps. Small tweaks can make a big difference, so re-test after each change. With some experimentation, you’ll dial in a curve that keeps your graphics card cool during intense use.
