Hello, i have a Macbook Air A1466 820-000165 where the fan is constantly running 6200rpm, as soon as i hit the power button.
I already tried a different fan, reset of SMC and PRAM. No difference.
So i measured the voltage on the connector
1:5V PP5V_S0
2:1.6V TACH
3:4.6V Motor Control
4:0V GND
I checked HW Monitor temperatures are in the normal range, no missing signals.
What can i check next?
