I upgraded HWiNFO to v8.22, and noticed very strange spikes in CPU core frequency.
On version 7.72, which I used before, such oddities were not observed - HWiNFO readings mostly corresponded to readings of many other monitoring programs.
My processor switches between 4 states: multipliers x4...
@red-ray gave me an idea, and I found a solution to tell the NCT6776 chip to display CPUFANIN speeds correctly.
Logical Device 08 -> Command Register F1 -> bits [6]:[0]
0:1 - take Count/RPM from 4-pin PWM connector [default]
1:0 - take Count/RPM from 3-pin DC connector
Yep. I have big GeminII cooler with 2x 120mm fans. Also 90mm fan for mobo blowing.
I don't use any software from ASRock.
But I want to note that if, after starting HWiNFO, I run AIDA64, which shows fan sensors, then fan sensors appear in HWiNFO too.
PS. It is possible that the ASRock...
