Koppar är en bättre värmeledare ja... men kolla denna lilla debatten
"Wow, I see a lot of different theories here. The truth, as I understand it, is since aluminum is less dense then copper, it cools off faster, but it also can't "hold" heat as well as copper can. It is about 3x cheaper than copper, and has a lower thermal coefficient. Copper: 401 W·m−1·K−1 Aluminum: 237 W·m−1·K−1. There are a lot of factors that come into play here, but this should perform better at a substantial increase in cost and weight. The redistribution of the pipes also will help improve things. One thing is for sure though, with an all copper heatsink it will definately feel warmer."

Tycker att den riktiga frågan är; Vilka av dom leder bäst per kg?
