HWiNFO does not show CPUFAN sensor from NCT6776F chip on ASRock 970 Pro3 R2.0 mobo

Debug log attached.

Are those fans spinning? Because raw data show all fans off.
If yes, will they show up when you run the ASRock A-Tuning tool?

Yep. I have big GeminII cooler with 2x 120mm fans. Also 90mm fan for mobo blowing.

If yes, will they show up when you run the ASRock A-Tuning tool?

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 implementation of sensors is a bit strange.
There are two connectors on the mobo itself: 4-pin CPU_FAN1, which controls only PWM fans - if I connect a 3-pin fan to it, it just will rotate at maximum speed; and there is 3-pin CPU_FAN2, which controls only 3-pin DC fans.
My CPU cooler has two fans with 3-pin connectors, so I connect them to CPU_FAN2 via a 3-pin fan splitter.
But in any case, AIDA64 can display the speed of all fans, even case fans.

OK, I will try to solve this in the next (Beta) build.

I ran AIDA64 and then ran HWiNFO to display the fan readings. Debug log attached, but I don't know if it will be useful.

@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
