I just recently downloaded the software for the first time and I was following a video to set up the fan cooling so my computer can run at lowers temps. The video showed an option for the GPU fan. My only options are CPU fan (now called Fan 1 & 2 for some reason), Fan 2, and Fan 3. In the video, it showed GPU Fan where it says Fan 3 for me. But the options for Fan 2 and Fan 3 are greyed out and I cannot manipulate them. I am running on an old Alienware 18 laptop. What can I do?
