Run real temp and click the test sensors button. Make sure your cpu is idling. If the different between the sensors is 3 or greater then that means your sensor is outta whack. for example if Core 0 has a sensor movement of 3 but Core 1 has a sensor movement of 2, nothing to worry about. But say Core 0 has a senor movement of 3 and Core 1 has a sensor movement of 6. That is a difference of 3 or greater, so that means your temp readings will be inaccurate.
