Good afternoon, at first this mac turns on but the image varies sometimes and locks, replaces the u9300 with a new ISL62882c, in tests the mac turns on but without image, can you tell me which pads I can test to identify if this component I bought is defective ?

You can tell me if C9319 has a resistor ? because I ended up bumping into this capacitor and putting a resistor in place, but I put the 1000PF capacitor in this pad.

I resold the U9300 back to display image, but in tests the cooler speeds up a lot and the machine is slow, I installed the HWMonitor, it follows the sensor readings.

u9300:
16- 5.03V;
17-12.63V;
25 - 5.04V;
38- 3.3V;

I disconnected, but still with the accelerated cooler, which component is responsible for the GPU 2 Die ? when I took the IC I ended up bumping into some components could you tell me if the R9314 its value is 1MΩ in the electrical scheme ? And if it has a resistor right there.

R9314 It's ok.
Still with accelerated cooler, I need to know when the u9300 terminal is responsible for the GPU sensor ?

Both heatpipe temps still high?
Check in System Report which graphics card is in use.
Be sure all components are in place.

There should be a sensor issue, or device connected in the same bus.
You have heatpipe temp errors, apart of GPU die.
