Liquid damaged board, all other faults fixed but this one with the fan.
ASD reports unable to stabilize between min/max speed.
Fan is not speeding up on fan test.

Replaced fan twice.

3V3 getting through R6010 = 0Ohms
Fan tach R6065 = 47k
R6061 = 100k
R6060 = 47k

Replaced Q6060 to be sure.

Is SMC_FAN_0_CTL a PWM control?
What to look for now?

Cheers

0.473V diode mode on FAN_0_CTL
I'll just bung on a new SMC on and see what happens
