Do you need clarification about why your GPU fans turn on and off randomly? Don’t worry! Let’s explore the interesting world of graphics card cooling systems together.
Your computer’s GPU fans switch on and off to keep your graphics card from getting too hot. When you’re doing a lot of stuff that makes the GPU work hard, like gaming or video editing, the fans start to cool it down.
I’ve noticed that GPU fans can switch on and off unexpectedly. I’ll share what I’ve learned so you can keep your system running smoothly, too.
Reasons For GPU Fans Turning On And Off – As My Experience!
Here’s some basic info on why your computer’s GPU fans might turn on and off:
Temperature Regulation:
When your graphics card gets too hot, its fans start spinning to cool it down. They work to cool it down by blowing air over its components. Once the temperature decreases to a safe level, the fans may turn off until needed again.
System Load:
When playing games or editing videos, your computer’s graphics card works harder and gets hotter.
This triggers the fans to turn on to maintain a stable temperature. When the load decreases, the fans may switch off to conserve power and reduce noise.
Custom Fan Profiles:
Some GPUs come with software that allows users to customize fan settings based on their preferences.
You may set the fans to turn on or off at specific temperature thresholds or adjust their speed manually.
Faulty Hardware Or Software:
In some cases, GPU fans may turn on and off unexpectedly due to hardware malfunctions or conflicts with software drivers.
This can result in overheating or system instability and may require troubleshooting or replacement of the faulty component.
Dust Buildup:
Accumulated dust on the GPU heatsink or fan blades can hinder airflow and lead to overheating.
As a safety measure, the fans may intermittently turn on and off to try and dislodge the dust or prevent further buildup.
Ageing Components:
Over time, the little parts in your computer’s graphics card fans can get worn out. This can lead to them not working properly or making weird sounds.
This could make the fans start and stop unexpectedly because they’re having difficulty working properly.
Power Supply Issues:
Insufficient power from the PSU (Power Supply Unit) can cause fluctuations in the GPU’s operation, including its fans.
Upgrading to a higher wattage PSU may stabilize the system and prevent erratic fan behavior.

- GPU Monitoring Software: Many third-party software tools are available to monitor your GPU’s performance and temperature. Programs like MSI Afterburner or GPU-Z can give you real-time information about your GPU’s status.
- Benchmarking: Running a GPU benchmarking tool can help you assess its performance under load. Programs like FurMark or 3DMark can stress test your GPU and give you an idea of its capabilities.
- Driver Updates: Ensure that your graphics card drivers are current. Outdated drivers can cause performance issues or prevent your GPU from functioning properly. You can update your drivers through the GPU manufacturer’s website or software.
- Temperature Monitoring: Make sure to regularly check the temperature of your GPU to make sure it’s not getting too hot. High temperatures can cause your electronic devices to malfunction or stop working altogether. Most GPU monitoring tools show the temperature.
How Do I Fix My GPU? Fans Keep Turning On And Off!
If your GPU fans keep turning on and off, there are a few steps you can take to try and fix the issue:
- Check for Dust: Dust buildup can cause your GPU fans to malfunction. Periodically maintain your GPU and its fans using compressed air or a soft brush for cleaning.
- Ensure Proper Ventilation: When the air doesn’t flow well in your computer, it can get too hot. This makes the fans act weirdly. Ensure that your case has adequate ventilation and that nothing obstructs the airflow around your GPU.
- Update Drivers: If the drivers for your computer’s graphics card are old or not working right, it can cause problems with the fan. Ensure you get the newest drivers for your graphics card straight from the company’s website.
- Monitor Temperatures: Utilize software applications to track and manage your GPU’s temperature. If it’s reaching high temperatures, it could be triggering the fans to turn on and off rapidly. Consider adjusting fan curves or increasing airflow to keep temperatures in check.
- Check for Faulty Hardware: If nothing else works, there might be a problem with your GPU or its fans. You may need to contact the manufacturer for further assistance or consider replacing the faulty components.
