Hello, I was able to read the fan speed by playing on SSDT-FANREAD.aml. But the value read appears to be constant on HWMonitor, it does not change.

Problem solved

I was able to read the fan speeds instantly.

I'm curious, how you solved it? I did a Hackintosh on my laptop but I can't set the RPM value

It still works with OC and Fakesmc3. By removing virtualsmc and satellite kexts, Fakesmc3 can be installed.

We install 3 kexts in the file we downloaded from here;
FakeSMC.kext
ACPIMonitor.kext
IntelCPUMonitor.kext


I have also edited and added SSDT-FANREAD.aml, this way it looks healthier in CPU readings. Here is the detail; By extracting your acpi files with Hackintool, it was reading the fan speed when you found your EC path here and entered it correctly in the .aml file.

For example;
External (_SB_.PCI0.LPCB.EC__, DeviceObj) // (from opcode)

I changed this and the EC path in other lines.

External (_SB_.PCI0.LPCB.EC0_, DeviceObj) // (from opcode)

It's listed as EC0 for me.

With your method above are you able to adjust the fan speed?
