No signs of water damage at all.
q7100 burned and ruined the traces under it, so after scraping away the damage and making sure nothing was shorted, i soldered a new one upside-down stuck to L7100, and the fan spins!, until the new q7100 gets hot enough to melt the solder on it within a few seconds, ruining q7100 and it gets stuck open, and did the same thing with another.
the rail it is switching has a 0.003 drop to ground, witch i figured was normal since it is low voltage cpu rail, I'm thinking the cpu is bad, and will simply kill any q7100 i put there.
looking for any input, because it sounds like a rabbit hole to me.
