Are you sure SMC was not changed with 3437 model?
That can explain fsan behavior.
However, board should still boot.

PLT_RESET_L comes high?

Nothing changed. Its untouched board.

PLT_RESET_L is 3.3V

Now the FAN behaviour is normal.
Spins normally. But doesnt boot.

ALL U1950 Votlages present till the fan is spinning.
