Huh? Current draw has nothing to do with CPU temp. 130f is too hot for the Pi CPU, but you're the engineer. I'm a dumb bilogist. Carry onI'm running the SystemTempSensor addin on CraftBeerPi. It reports the internal temp of the RPi3. I added fans to the enclosure to remove the heat created by the induction coil. I'm seeing about 130F during the boil.
I'd check the current draw on your GPIO pins.
