How To Speed Up A Graphics Card’s Fans

When you’re deep into gaming or running heavy graphics applications, the last thing you want is your GPU overheating due to inadequate fan speed. Let’s walk through how you can speed up your graphics card fan to ensure your system stays cool and performs at its peak.

Understanding Graphics Card Fan Functionality

Graphics card fans are critical for maintaining an optimal temperature of your GPU during intensive tasks like gaming or video editing. As the GPU’s workload increases, so does its temperature, necessitating faster fan speeds to dissipate the heat efficiently. However, sometimes the fans may not respond as expected, which is when manual intervention becomes necessary.

How to Speed Up Your Graphics Card Fan

To take control of your GPU’s cooling, we’ll use MSI Afterburner, a robust utility that works with various graphics cards, regardless of the manufacturer. Here’s how to set it up:

Step 1: Install MSI Afterburner

  • Download MSI Afterburner from the official website.
  • Install the program by following the on-screen instructions.

Step 2: Configure Fan Speed Control

  • Open MSI Afterburner.
  • Click on the gear icon to access settings.
  • Go to the Fan tab and check the box for ‘Enable user-defined software automatic fan control’.
  • Adjust the fan speed curve to your preference. For heavy gaming, ensure the fan speed is set higher at temperatures starting from 65 degrees Celsius. You can add temperature points by clicking on the curve line. Don’t forget to save all your settings and profiles!

Step 3: Test the Settings

  • After configuring, launch your game or any high-load application to test the new fan settings.
  • Observe the fan speed and temperature in MSI Afterburner.

Signs of GPU Overheating

  • Stability Issues: If your PC crashes or freezes during high-end tasks but works fine during light activities, your GPU might be overheating.
  • Graphical Artifacts: Unusual lines or colors on the screen can indicate an overheating GPU.
  • Unexpected Shutdowns: If your PC shuts down or reboots suddenly while gaming, it’s a critical sign of overheating.

Preventive Measures and Fixes for Overheating

  • Ensure Free Fan Movement: Check inside your PC case to make sure nothing obstructs the GPU fans.
  • Clean Your Graphics Card: Regularly dust off your card using compressed air. Always wear protective gear to avoid inhaling dust.
  • Replace Thermal Compound: If overheating persists, consider reapplying the thermal paste between the GPU and its heatsink.
  • Check Overall Cooling: Evaluate your PC’s case ventilation. Poor airflow can exacerbate overheating issues.
  • Inspect Power Supply: An old or failing power supply can contribute to poor performance and overheating.


Keeping your GPU cool is essential for maintaining performance and longevity of your system. By manually controlling the fan speeds through MSI Afterburner and ensuring your system is clean and well-maintained, you can significantly improve your graphics card’s efficiency and prevent potential overheating issues. Remember, a cool GPU is a happy GPU!
