Hi everyone.

I changed the processor to imac 2011 21.5 and it damaged something. The gpu heatsink temperature sensor disappeared from the system. And now the processor is working at half its strength. Apple test shows error in tg0h.

I re-glued the temperature sensor from the dvd and connected it to the same input, but this did not solve the problem.

Is there a known weak point in 21.5 where the resistor could fly off?
Or can I somehow emulate a sensor for the system?
