Chosen Solution
I’m certain that my Palm rest temp sensor (aka TS0P) is faulty as I can see the reading from iStats as -128, which fires up the fan speed to max and kill CPU power and Wi-Fi Question is: Is there a way to tell the mac to ignore these readings or replace it? According to what I read; this sensor is in the cable of the trackpad. Can you confirm this is the case?
Guys I solved the problem! It was !&&* of a 8 months of searching and debugging. I wrote a post about it here: https://addaxsoft.com/blog/dyi/fixing-fa…
Replace the trackpad cable (usually people sell the cable with the trackpad, not the cable on it’s own). If there is an issue with the cable, or the MacBook doesn’t detect a trackpad plugged in, the fans will spin up since it has no reading from the sensor.
Try to unplug the webcam, wifi, Bluetooth and trackpad cable and see if that makes the temp go down,
for those that removing TRACKPAD FLEX from connector (J5800) and the issue is still there, remove CAMERA FLEX too, the SMBUS_SMC_A_S3_SDA goes to camera connector (j3402) pin 4 and SMBUS_SMC_A_S3_SCL pin 5.
