Hello I'm trying to disable my dGPU. It's constantly running hot while both two fans are running. I've already looked around online deep searching in google, reddit and tonymacx86. I already tried the above following guide and also the "Device Properties" Method. Still it's running hot with the fans continuously. I don't know what else to do.

Here is my config.plist and the SSDT-GPU-DISABLE.aml

Thanks in advance for anyone trying to help me solve this problem.

Cheers.
