The rest should be all additional case fans along with a dedicated card for the graphics card/GPU fans. If you have connected the CPU cooler or a liquid cooler pump to the CPU fan header, it should be Fan #1 by default. For instance, the first card, Fan Control #1, should be the control for Fan #1. Each card under the Controls section corresponds to a card in the Speeds section. Step 2: The main home screen of the software is divided into two sections: Controls and Speeds. To run the tool, open the FanControl.exe file. Unzip the package and store all the files in a folder. Step 1: Download Fan Control from the official website, or its Github repository. Thus, any hardware compatibility issue completely depends on LibreHardwareMonitor and NvAPIWrapper.

According to the developers, the drivers and the backend portion of the tool have not been created from scratch. Fan Control is available for free from its Github page and the official website.
