Quick guide how to get sensors when using a Ryzen CPU with Arch Linux.
BEFOREHAND: if this does not work for you (modprobe returns an error), you might want to try the "nct6775-dkms-git" package instead of "it87-dkms-git". My old ASUS board needed it87, my new MSI board needs nct6775.
UPDATE FEBRUARY 2018: this procedure is still applicable since the only readout with the newest Kernel 4.15 is the k10-temperature (CPU). All other sensors are still not supported out of the box.
1 install kernel headers
sudo pacman -S linux-headers
2 install chipset drivers
yaourt it87-dkms-git
3 create file
sudo touch /etc/modules-load.de/modules.conf
4 add it87 to modules.conf
sudo (texteditor) /etc/modules-load.de/modules.conf (it87)
5 load modules
sudo modprobe it87
6 restart
sudo reboot
7 run
watch sensors
