Hvor jeg har det ifra ?

Er iallefall sånn jeg forstår det.

 

Hvor har du det ifra om jeg tør spørre ?

les siste linjene: ''... Now let us go back to the aluminum versus copper debate. Copper’s higher conductivity means is that a thinner copper fin can transmit as much heat as a thicker aluminum fin. However, on a weight-basis, aluminum can conduct more heat than copper. If weight was no object, copper holds the edge. When weight is a limitation, aluminum has the advantage. Conductivity multiplied by density is a "weighted" measure of a material’s conduction efficiency. It is this "weighted" efficiency that leads to the use of aluminum in the fins/pins of many heat sinks. It is certainly not because "aluminum gets rid of heat better than copper". ''

Hmm, artig. Eg trudde faktisk du hadde frå ein annan artikkel på AMDMB, nemlig denne:

 

.. silver plated copper alloy core for maximum heat absorption with an aluminium top for maximum heat dissipation.

Eg syns likevel at utdraget som nOne kom med oppsummerer saken ganske godt, sjølv om det ikkje er 120% riktig det heller
