Current graphics cards have an increasing number of fans, which have been updated to offer extra features such as idle stop or pulse control (PWM). But while this is great, there are still many users who do not know how to control or decrease the RPM of such fans at will. So today we show you how to do it very simply and with a single program.
Many users find noise levels that they are not willing to support in their GPU, either because they need maximum silence when sleeping, because they value maximum silence or because the manufacturer has simply put a very aggressive curve between temperature and RPM. For this reason, we are going to use the famous MSI Afterburner, with which what we are going to achieve is to control this whole thing to our liking.
How to control the RPM of the fans of a graphics card?
We start from the basis that we have downloaded the MSI Afterburner program from websites such as Guru3D or from the developer’s own website , after which we must install it. Keep in mind that the program includes Rivaturner, so we will have two installers, that is, we will have to install the two programs, something that is totally automatic when running MSI Afterburner, because first it begins to install this and in the middle of it we it will ask to install RivaTurner , once the latter finishes it will continue to install Afterburner.
Therefore, once the PC is installed and restarted, we will proceed to open the program, after which we will have an interface like this:
The interface is simple, it is even customizable, but the parameters may change places, so we will continue with this one, which is the standard within the same program.
The first step to modify the RPM is to click on the button where it says auto, within the Fan Speed% section, since there we will tell the program that we want to take control.
Once the slider is unlocked, we can adjust the percentage of the fan PWM at will, reducing or raising it as we see, after which we will have to click on the check box as shown in the image below.
Once applied we will see how the RPM of the fans change. There are some cases that even if the program indicates that we can really change the revolutions, the fan or fans do not allow it because they are fixed, but that should be in old models where there is a false reading.
We can also save this parameter in a preset , so that every time we open the program it is applied, or that it is applied only when Windows starts. To do this, once we have the RPM in percentage applied through the slider mentioned above, we will go to the section at the bottom right: Profile .
We see up to 5 different buttons to press, as shown in the image above. We will only have to right-click each one of them and confirm with the left mouse button on the same number to set it, after which we will click the disk icon that is just to the right of these buttons.
This is how the profile will be applied when we click on that number. If we want this to be automatic when Windows starts, what we will have to do in addition to what has been said is click on the Startup button, located on the left in parallel with the profile buttons.
This way, the profile will be applied correctly at each Windows startup without having to touch anything else, since the RPM of the fans will be changed by themselves.
