There are a lot of different programs that control this process, but the easiest and most versatile is by far MSI Afterburner.Īfterburner (and other programs like it) allows you control everything from clock speed, temperature limit, voltage as well as the speed of the fans in your system. Once you are going over the allotted ability of your GPU to cool your system down, there needs to be a way to change the speed of the fans yourself. How to Control GPU Fan Speed A screenshot from the MSI Afterburner application.
When these processes are activated, you might feel the PC getting too hot for the fans to handle and when that happens, we need to figure out a way to manually control those fans. This is especially true when it comes to the usage of overclocking and other PC tweaks intended to increase performance. Sometimes, the fans won’t run as fast as you need them to. They are built to kick into high gear when intensive programs start to play, so that’s just the fans doing their job.
If they are running pretty fast, this can be a bit startling and you may think something is wrong, but don’t panic. This is not some phantom process that you have to hope is working, you can hear whether they are running fast or not. Once you start playing the big-time games and programs though, that is usually when you hear the fans pick up speed. When the PC is at rest or running a very small number of programs, these fans don’t factor in that much. Luckily, this is where the fans come in on models that get too hot to handle. Unfortunately, sometimes this heatsink is not nearly enough to keep things cool enough to keep stable. – For CPU and GPU together, we have a really helpful guide to how to generally adjust your PC’s fan curves too.ĥ Final Thoughts & Recommendations How GPU Fans WorkĮvery GPU comes with a natural part installed called a heatsink which will effectively act as a cooling system when things start rolling on your PC. This quick guide will cover everything you need to know about how to set your GPU fans and how to make sure things are running optimally. This is especially true if you’re getting into overclocking. Your GPU should already have its own systems in place to regulate its temperature, but sometimes you’ll need to go above and beyond to manually control things. When things overheat, the result can end in crashes, parts of the PC malfunctioning, and all-out system failure in the most extreme cases. Sometimes, your hardware or software cannot keep up with how hot everything is getting and the fans might not be running fast enough to keep the system cool. When you are running intensive programs, especially video games and video editing software, your GPU fans are naturally going to run faster in order to cool down your PC. Wondering how to optimally control your GPU fans or troubleshoot overheating cards? We can help!
