Voltage, temperature, and fan speed reporting among desktop motherboards under Linux remains one of the unfortunate areas even in 2021... Many SIO ICs remain publicly undocumented and the Linux driver support is often left up to the community and usually through reverse-engineering. Thus the mainline Linux kernel support is left to suffer especially among newer desktop motherboards. At least for Linux 5.12 some ASRock motherboards will begin seeing their voltage/temperature reporting now function.
