Please update CPUID HWMonitor to the latest! After reviewing the information provided, I found nothing wrong, but the question lies on how many fans on your computer? Generally speak, the fan speed of System Fan is constant rather than manipulated by the ICs. So the values (percentages) are meaningless. You might use a constant fan to cool your processor too, so its speed does not change and stay at 100%. Or you did not enable SMART FAN feature under BIOS/SETUP/UEFI.
