Have you tried to install the it87 driver for your kernel? https://github.com/frankcrawford/it87 (on AUR it's it87-git)
I have ASUS B450M PRIME GAMING and after installing the driver, the chassis fan sensors were detected and I could use CoolerCtrl to draw the fan curve.
I don't quite like CoolerCtrl because of its UI, seems to be web based, but it works and has a daemon mode to start minimized on startup.
I found Tailscale/Headacale way more difficult to setup than Wireguard.
