hwinfo not reading cpu fan speed, but if I install axtu (asrock extreme utility tuner), cpu fan speed pop up in hwinfo to 0 rpm. In bios the rpm is reading. Only with cpu fan1 the issue occours. Cpu fan 2 and the other chassis fan are reading in hwinfo. Please help me. Any chanches to further improve bios hardware monitoring with a modded bios? in bios hardware monitor, che cpu1 fan speed is reading to n/a. after a while, the reading is correct, why?
Thancks

@ Wire11:
Welcome at Win-RAID Forum!

I cannot help you with this.
You should better ask the ASRock Support, because this seems to be either a mainboard or a BIOS issue (or a HWInfo one).

Merry Christmas and a Happy New Year
