FAQ

Why is copper based heat sink better than aluminum based solution?

The short answer to the question is the fact that copper conducts heat better than aluminum. Engineers utilize thermal conductivity (W/m*K) value to measure the effectiveness of a material. In this case, copper has a thermal conductivity of ~401 W/m*K and aluminum is ~237 W/m*K. To put it in perspective, wood has a thermal conductivity value of 0.04 ~ 0.4 W/m*K and concrete is 1.7 W/m*K, that is why wood does not get quiet as hot as concrete on a hot sunny day.
