It looks like the board has been previously ultrasonic'ed so Im trying to figure out where the corrosion was, I don't have ASD162 but have attached the Istat Sensor readings, nothing looks too out of place but you can see the fan is running at over 6K. Computer seems to run a little slow at times too.
Where should I look first for readings, usual suspects?
