Kernel task running high and overheating the CPU - Surface Book 2

[zukulento]

I've installed Ventura in my SB2, but the CPU is always running high and that overheat the laptop. Usually it sits at 39°-45°, but now with the kernel task running that high temps stay at 60°+.

I read somewhere that the cause could be a kext or ACPI that shouldn't be there, so i booted with the minimun.

I tried:

1. Boot with no files in the ACPI and only lilu, whatevergreen and VirtualSMC.

2. Boot with only an ACPI at a time.

3. Install Bigsurface kext.

4. CpuFriend and CPUFriendDataProvider.

5. Disabled backlight and audio.

Also i first installed using the olarila ISO and EFI folder had the same problem. Tried using my own EFI folder and had the same problem. 

The installed thru the dortania guide and the same thing.

 

Nothing of that worked

Help pls

Hey!

I tried but its the same thing.

I have a DSDT file, the thing with that is that it gives me this "ACPI Error". I was advice that i should delete the entry that gives me error, but i dont know how.

Here is the EFI with that DSDT file. https://www.dropbox.com/scl/fi/tlck3y2dvlru4i4zk7r4o/EFI.rar
