PP3V42_G3H is way to high, are you sure about where are you measuring??? Also PPBUS_G3H is higger than normal.... On this logic board is normal not to have a fan spin when power on!!

Is PP3V3_S5 present? Are you using a known good ORIGINAL 60 or 85W charger?

Fan will not spin until the CPU heats up, so no use to have that connected.
