For a gaming computer, the GPU is conclusively the most important hardware component. It provides all the horsepower required to run any game and also assists in other processes, such as rendering and streaming. However, GPUs are also expensive and if one dies, there’s only a minor chance for it to be repaired.
So, you just got your new GPU for a few hundred dollars! You install it into your computer and turn it on, but wait; the GPU fans are not spinning. Why is that? After all, you purchased a new GPU. Whether you use an AMD or an NVIDIA GPU, there’s a chance that you won’t have the fans spinning all the time. In this article, we will explain what causes the GPU fan to not spin and how you can resolve it.
WHY YOUR GPU FAN IS NOT SPINNING?
If you just turned your computer on with your new GPU, there’s no need to worry if the fans don’t spin. When you’re not doing anything on your computer, it’s in an idle state. This means that your computer is not running any hardware-intensive process.
Hence, your GPU is not being used. Instead, other hardware, such as your CPU or RAM is being used. You can confirm this by opening either the Task Manager or if you’re using an AMD GPU, the AMD Radeon Software. From there, you will notice that your GPU usage is between 0% to 10%.
However, as soon as you open any GPU-intensive process, such as gaming or rendering, your GPU usage will increase up to 100%, depending on how GPU-intensive the process is. When your GPU is idle, the temperature is not that much. Therefore, your fans don’t have to spin to cool it down. However, as soon as you run a GPU-intensive process, the more your GPU is used and the hotter it becomes. As a result, the fans start to spin, to control the temperature.
However, there can be instances where you’re running a GPU-intensive process but the fans won’t spin. This could be a result of defective fans or PCB, or incorrect GPU settings. If your GPU is defective, you may want to take it to a repair center or claim the warranty. But, if that’s not the case, you should configure some settings in your GPU software or motherboard’s BIOS.
HOW TO CONFIGURE GPU FAN SETTINGS?
If your GPU fan is not spinning, we would not recommend you run any GPU-intensive application until the issue is resolved. Not only can that be detrimental to your GPU, but it is also a potential fire hazard. If you recently overclocked your GPU, you may have changed the fan settings. To resolve this;
- Open the application that you used to overclock your GPU. In this case, we will use MSI Afterburner.
- You will notice an option for Fan Speed (%) or Fan Speed (RPM); we would recommend that you change it to Auto.
This will allow your motherboard to change the fan speed according to the temperature of the GPU. If you’ve overclocked your GPU, you may have to set custom fan speeds for the optimum temperature. For that, you should consult this How to overclock your graphics card article by PCGamer.
CHANGE YOUR GPU FANS:
If all else fails, there’s a chance that your GPU fans are defective. For that, you’ll have to either take your GPU to a repair center or install the new fans yourself (only if you know how to). You can remove fans out of an old GPU and install those or you can order spare fans online, which cost around $15 for one fan.
