core 3 of quad core CPU always lower temp?????

It's normal, at least in my experience. I'm not sure, but it might have something to do with where the sensing diode is located on the chip.

i do believe this is the answer.

Or the part where that core is has best contact to cooler.

very unlikely to provide such a dramatic change.

Silicon is not exactly a good heat conductor.. core three probably gets the greatest benefit from your cooling fan.. may be as simple as that. Every multi-core system I've ever monitored the temperatures of usually has one core that averages a couple degrees higher than the rest
