Unless I'm mistaken, they're just little thermocouples. They'll tell you the temp of wherever they are, so they need to be affixed to the surface of something if you want to know that specific component's reading, instead of the ambient air around it.
Why is it you're having trouble monitoring your core temps? Those should be from sensors on the motherboard itself
