That's not a bug, it's a feature. The CPU sensor on the board itself is broken (stuck) on a wide variety of Asrock boards. I don't have a handle on whether it's some boards or all boards, but I certainly have one (X470 Taichi ultimate where the board CPU sensor reads 40C no matter what). I've no idea what the underlying sensor issue is, but apparently it's not fixable from the BIOS, so they just disabled it....
The good news is that I’ve read that the latest updates for many boards, which is BIOS 5.50 for the X370 Taichi, finally solve the freezes. Unfortunately, this BIOS for the Taichi also introduces a nasty new bug : if my understanding is correct, if you select CPU for the fan control source, it now monitors the Tdie, which varies a lot, instead of the CPU sensor on the mainboard. I think I’m going to wait before update the BIOS
