Controlling each of these PC fans may seem quite complicated at first glance, but in reality, it’s not at all. The technique shown in this blog post will use the BIOS instead of software, which is a plus because you won’t need to install anything extra. This method works for all fans connected to the motherboard, including those on a water cooling system. If you’re already on your desktop, hold down the Shift key while clicking on Restart. You should see a blue screen with troubleshooting options. Click on « Advanced options » and change the UEFI firmware settings. Then, restart your PC, and it will automatically load the BIOS.
To access the BIOS on ASUS motherboards, press the designated key. In the « Monitor » section, you’ll find an option called « Q-Fan tuning, » which automatically analyzes and adjusts all your PC fans. This is a good alternative for those who prefer a hassle-free approach. However, if you want to manually adjust the fan settings, simply go to « Q-Fan Control » at the top or press F6. The process is similar for other motherboard brands like MSI and Gigabyte.
By default, most fans use Pulse Width Modulation (PWM) to automatically adjust their speed based on your PC’s temperature or processor heat. However, if you want more precise control over PWM settings, you can switch to manual mode. Don’t forget to change the « Speed Control » mode to manual, or else the options will be grayed out, and you won’t be able to adjust the fan curve. On the left side of the screen, you’ll see the fans connected to the motherboard via the « Sys_Fan » or « Cha_Fan » ports, with the specific port name displayed at the bottom of the curve.
There are several predefined modes available, and the « Full Speed » mode can provide a quick cooling boost for a minute or two, for example. The vertical axis represents fan speed from 0 to 100, while the horizontal axis represents temperature in degrees. You can also adjust the pump speed, but it’s usually set to 100% by default, and I recommend leaving it as is, as it’s factory optimized. Feel free to experiment with your own settings and observe how your system reacts. Once you’re satisfied with the values, remember to save your changes by pressing F10 or navigating to the « Save & Exit » tab.
