I have an MSI H170 Gaming M3 motherboard, and KDE Neon doesn’t detect none of my fans at all.

$ sensors

Any idea why it doesn’t show up?

As far as I can tell from this review, your motherboard uses a NUVOTON NCT6793D – Super I/O Chipset. Support for this chipset is in the NCT6775 kernel driver.
You can try loading the module manually with:
sudo modprobe -v nct6775
If it works, you can add the module to your /etc/modules file for automatic loading on boot.
