Graphic Processing Units (GPUs) are the most important peripherals of a computer when gaming, video editing, or even rendering a 3D model. They perform tedious and resourceful tasks for the system, but there is a caveat. GPUs can overheat to the point that it would damage the system, affecting both performance and lifespan. To ensure your GPU is cooled adequately can be achieved through increasing the fan speed. In this article, we will explain the methods that can be utilized to safely increase the fan speed and why it is critical to do so.
An Overview of Why Is GPU Fan Speed Important And How It Helps To Optimize Output
A cooling fan for GPU has the sole purpose of getting the heat produced by a PC’s gaming graphics card and getting rid of it. In the event that there is a GPU intensive workload, the GPU would output an exorbitant amount of heat. If that excessive heat is not managed, it can lead to thermal throttling, which means that the GPU will throttle its performance in order to manage its overheating. If, over a period of time, that heat is not controlled, It will damage the GPU.
GPU fans are typically tracked through revolutions per minute (RPM) as the measure of how efficiently the fan works towards cooling the GPU. The cooling performance can be controlled through the adjustment of the fan speed. However, fans that are overly cooled run the risk of GPU overheating, while GPU that is undercooled never adds any real value to the overall cooling efficiency.
The ABCs: Explaining The Function Of GPU Fan Speed
Most modern GPUs have at least one or two fans installed, which come with variable speeds corresponding to the rotation. The TPU fans’ rotation is determined by the temperature of the GPU at that specific time, along with the load. This is often the responsibility of the GPU’s internal thermal machinery, which controls fan speed in relation to the recorded temperature.
A good example of thermal management in GPU is where the fan speed increases when the GPU temperature is too high. While the GPU is idle, under low usage or gaming and rendering videos, the fan can rotate slowly or set higher RPMs which increases speed.
Manual controls are useful in bringing fan speed to an optimal level to fit individual requirements. Fans that are adopted for other use cases often have manual controls that try to eliminate the gap.
Why Managing and Optimizing Your Fan Speed Is Important
- Overheating Problems: Performance throttling, sudden system crashes and damage to any component, for the matter to your GPU, can all stem from overheating. With the right fan speed, your GPU will be able to function at maximum efficiency all the time without any overheating problems.
- Noise Pollution: The GPU, when not loaded, can also utilize a spinning fan on the GPU for noise reduction. If that fan has uncontrolled rotational speed, in other words, if it requires some throttle, the fan can, when set at the proper speed, reduce noise without hampering cooling requirements.
- GPU Life Improvement: Proper cooling extends the life of the GPU. Maintaining proper temperature limits prevents overheating, which results in excessive damage and wear and tear to all computer components.
- Performance Maximization: Adjustment of fan speed aids in finding the perfect compromise between managing extreme cooling levels and peak performance. A good illustration is overclocking wherein management of heat requires additional cooling.
Overheating GPU Fan Speed Adjustment Monitoring
Monitoring the temperature and RPMs of the GPU fans is the first step before any adjustments are made to speed. For monitoring purposes, there are tools available that can be used for probing the GPU’s health:
1. GPU-Z
- Features: GPU-Z is very simple and helps to keep device information like fan speed, temperature, and clock speeds in check as it is one of the lightest utilities.
- How to use it: If you have downloaded GPU-Z, you can proceed to install the application. Once the installation is complete, you can open the app and navigate to the sensor tab, where you will be able to see the live activity of the GPU fans along with the temperature and RPM.
2. MSI Afterburner
- Features: This software is widely used for GPU monitoring and overclocking. Real-time temperature, fan speed and voltage monitoring with fan speed auto-control are also supported.
- How to use it: You will be able to see many indicators on the graph that MSI Afterburner displays after launch, including fan activity. The app allows to set temperature controls so that once a certain value is crossed, the fans will automatically start spinning.
3. HWMonitor
- Features: In addition to GPU temperature monitoring, HWMonitor provides information on the fan speed and power usage of the different parts of your PC.
- Features: GeForce Experience is NVIDIA’s proprietary software that assists its users with game optimization and GPU management. They also keep track of temperature and fan speed.
- How to use it: As soon as you install GeForce Experience, you will find the Performance tab in which you can enable FPS Counter and Thermal Monitoring features. Activating these two options will enable you to monitor fan speed and the GPU temperature during gameplay or other load situations.
- How to use it: With HWMonitor installed, open the application to be presented with your GPU’s details and any problems you may encounter. The application will display the fan speed and temperature to help you assess if there’s any thermal issue.
- Features: Yet another commonly used tool for NVIDIA GPU powers is EVGA X1 Precision. This software also has the most temperature monitoring functions, fan speed, and clock speed for the GPU, and even adjusts fan profile parameters.
- How to use it: Run Precision X1 and it will immediately provide you with real-time data from your GPU. Other options include producing custom fan cooling profiles that optimize temperatures, fan speed, and even clock speeds.
Edit the GPU fan speed parameters
Understanding GPU fan speed control along with GPU temperature monitoring requires knowledge of speed fan precepts first. This section teaches you how to adjust fan speed for optimal cooling.
1. MSI Afterburner Usage
- Step 1: Open Ultra Afterburner and navigate to the FAN speed slider.
- Step 2: Set fan speed using the slider and ensure it does not exceed a 100% value. If the GPU temperature is significantly high, increase the fan speed to optimize cooling processes.
- Step 3: To change fan speed automatically, press the settings button and navigate to the Fan tab, marking “Auto Fan Control.” From this section, custom fan curves can be set, allowing the fan speed to change depending on the temperature thresholds of the GPU.
2. Custom Profiles for the Fan
- Step 1: Access the fan control section of the software you prefer as EVGA Precision X1 or MSI Afterburn.
- Step 2: In that section, you can go to the fan curve editor and set the necessary fan speeds for different temperature activations.
As an example, a fan set to 30 % turns on at a temperature of 40 °C, increases to 50 % at 60 °C, and will be set to a maximum speed of 100 % at 85 °C.
- Step 3: The final step requires saving the fan state, which will then allow the fan to turn on or off automatically.
3. Through GPU software (NVIDIA or AMD only)
- NVIDIA users can change the fan speed on GeForceExperience and the NVIDIA Control Panel. Many of these changes can be made with unsupported software, even though the basic fan speed options are more restricted.
- With AMD, users are allowed to change fan speeds and custom profiles for particular applications through Radeon Settings.
Important tips for effective managing of GPU fan speed.
Have A Look At The Temperature: ** Understand what your GPU’s upper limits are. Aim to ensure, though, that it does not cross over 80°C, or otherwise, it could permanently limit performance and ultimately destroy your GPU.
Noise to Cooling Ratio: In general settings, environments characterized as ‘noisy’ allow the user to set the fan at higher speeds in order to cool the system faster. However, this increases the noise. In situations where silence is sought, increase the fan curve so that the fan speed increases with temperature.
- Overclocking Considerations: In the event that you wish to extract extra performance from your GPU, ensure that your fan speed is set properly. This way, a higher GPU temperature will not reach unsafe levels.
- Regularly Clean Your PC: Dust buildup on your GPU and its fan can obstruct the proper airflow and the cooling efficiency of your GPU. This can throttle the capability of your PC. For maximum cooling efficiency, ensure that the insides of your PC are cleaned regularly, paying special attention to the GPU fan area.
Conclusion
Optimal fan speed has a direct impact on the efficiency of the GPU. The fan speed is part of a larger cooling system that maintains a GPU’s operational status throughout its lifespan. If a fan’s noise limit is raised while the GPU is already too hot, the system will not overheat. When one is playing video games, or during any processing demanding tasks, the ability of the fan to change speeds is invaluable. The user will surely gain more control over the components, thus enhancing their general experience with the computer.
