Arrived with liquid damage in PP3V42_G3H area. Replaced all components affected by spill and ultrasonic. Board now turns on but fan spins fast. Using known good trackpad IO board and flex. J9500 is in perfect shape... not affected by the spill. Diode mode on pins 11&13 is good at .654
resistors and continuity good around U5800. Replaced U5800 and U5810 to rule out but no changes.
Machine runs at normal speeds with working keyboard&trackpad just has fast fan.
what to check next?
