Summary0002023: Zotac H77 not recognized
DescriptionThe Zotac H77-ITX-Wifi motherboard gives odd readings.
(link gives high resolution images when clicked on "1:1")

I have put a Celeron G460 in it, which at 35W runs very cool. The BIOS screen reads 41°C whereas Speedfan reports 124°C. Ambient room tempature is about 25°C

System Nuvoton NCT6776F 61C
CPU Nuvoton NCT6776F 124C
AUX Nuvoton NCT6776F -128C
SMIOVT4 Nuvoton NCT6776F 62C
SMIOVT5 Nuvoton NCT6776F 62C
SMIOVT6 Nuvoton NCT6776F 62C
HD0 HD0 (640.1GB) 31C
Temp1 ACPI 28C
Temp2 ACPI 30C

System- and CPU fan speed are read correct (touching them reduces the rpm), but setting a lower speed doesn't change rpms (checked visually).
CPU fan speed is 1060-1100 rpm, system fan speed is 4150-4200 rpm which is higher than rated:

The BIOS update program mentions a "Nuvoton NCT5532D Super IO", if that's any indication.

Can you, please, upload (there is a button here for this) the output of a SEND REPORT (SpeedFan's INFO tab)?
