It's still suspect that all cores read exactly the same min, current, and max values. Regardless of how efficient the cooling is, that shouldn't be happening, as each core will be working on different tasks most of the time. I've never seen a rig display exactly the same values for all temps. Even if you have the best cooling in the world, there would still be differences across cores despite all temps being very low.... even if it's just one or two degrees... there would be something in one of those columns. For all three (min, current and max) to be identical is weird.
