There is probably something I am doing wrong, but I haven't had any luck so far with google so here is hoping someone smarter can help me. 'CoolBits' options 4 and 8 under Section 'Screen' in my nf. Using the 440.59 proprietary NVIDIA driver. (Screenshot of my Thermal Settings in nvidia-settings). Within nvidia-settings under Thermal Settings on my GPU it is only recognizing 'Fan 0' and this fan appears to be working normally, but otherwise it is completely missing the other 2 fans. Maybe I am missing something, but as far as I know nothing is wrong with the fans because Windows has no issues detecting all 3 of the fans. I have done some Googling around to find a solution, but haven't found anything that has worked so far. The only issue is that my system doesn't appear to be detecting 2 of the 3 fans on my GPU. The software overall is great, except the Curve setup, although I still rather use it than anything related to MSI.I have just recently setup Arch on a separate SSD and want to get my games library setup. Pressing 'X' will close it all up, sometimes messing up the custom settings. You also need to run X1 in the background all the time, if you tinker with the software, make sure to hit the '_' on the top right instead of 'X', that way it gets minimized and just runs in the background. Easiest setup is select 'Stealth', then move the lowest point to 30C and 14-15%, then check the Fan Curve Control box, and hit apply. It's also better to run the fans on a 14-15% bottom to prevent the annoyance of them turning on and off.

Leaving fans on Auto is not the best solution, since if you have bad airflow and/or left your preset on 'prefer maximum', your GPU on idle/desktop use will still consume over 30-40 watts, and heatsoak will be present. When you set up a custom curve, you need to do it with your mouse one by one in the default section, NOT in the VF Curve tab, then when you're done, press apply, select a preset number on the right, and press save.
