Which is better, notebook copper heat pipe pressing copper radiator or copper heat pipe pressing aluminum radiator?

Notebook copper heat pipe copper radiator and copper heat pipe aluminum radiator must be better than copper heat pipe copper radiator, because copper heat dissipation will be much better than aluminum, but the difference is not big. After all, it is used in notebooks, and the internal volume of notebooks is relatively small. I think if you pursue the next road, you'd better transform water cooling, but water cooling is generally not used in notebooks, so I think the difference between the two radiators you mentioned. In fact, the world is not big.
