> Enable the CPU_Opt fan sensor for ROG STRIX X570-E GAMING.
>
> The board has a CPU_OPT fan header, and its UEFI hardware monitor shows a
> fan connected to it spinning at about 2000 RPM, but the driver does not
> expose the sensor and the board's NCT6798D does not report it either.
>
> Reading the EC directly through ec_sys on this board (BIOS 4408), the
> CPU_Opt register used by the rest of the AMD 500 series family (bank 0,
> 0xb0) returns 0x0580, 1408 RPM under the operating system's fan curve,
> while the chipset fan register at 0xb4 returns 0, matching what the
> driver already reports for that fan.
