Hello!
Here is neccessary:

kextcache -i /
Executing: /usr/bin/kmutil install --volume-root / --check-rebuild
rebuilding local auxiliary collection
kmutil done

Mac Fan say in Russian: No fans find, try reset SMC

Thank you

The kexts are not being loaded in the correct order.

The correct order should be the following
VirtualSMC,
SMCSuperIO.kext
SMCProcessor.kext

To check whether SMBUS is loading or not, use the following command in Terminal.

kextstat | grep -E "AppleSMBusController|AppleSMBusPCI"

Thank you!
But change kext's order not work for me.
I try with SSDT-SBUS-MCHC.aml and remove it from config - result the same.

im confused

Thank you!
I add SMCProcessor and SMCSuperIO but can see only Core temp, still no fans.
I try without/with path but in both cases no fan.

May be i do something wrong ?
In Hackintool i see /PCI0@0/SBUS@1F,4 - it mean i must do PCI0.SBUS

in sample file i see:
External (_SB_.PCI0, DeviceObj)
External (_SB_.PCI0.SBUS, DeviceObj)

Scope (_SB.PCI0)
Device (_SB.PCI0.SBUS.BUS0)

May be this 2 bold must be equal ?
Like
External (_SB_.PCI0.SBUS, DeviceObj)
Device (_SB.PCI0.SBUS)

or
External (_SB_.PCI0.SBUS.BUS0, DeviceObj)
Device (_SB.PCI0.SBUS.BUS0)

May be i must do something here ?

This means the SMBUS drivers are loading.

The address doesn't needs to be changed as the device address is same as yours.
I tested it on a spare PC and it works at intended. Although, it has a issue with Custom controls. However, the temps and RPM are being shown.
You can use iStatsMenu to verify the temps and FAN RPM.

Ok, thank you! Its good.
iStatsMenu have the same situation - no proc temp and fan speed.
In BIOS i have 2 option for temp control - intelligent and static.
When i chose Intelligent - CPU fan have different speed depend cpu temp? when i chose static - fan work on MAX speed all time.
In both cases - no cpu temp or fan speed in tools.
