I have taken part in lots of technical debates , and in the recent the hot topic was about the heat sinks , and I was looking for true technical research on the subject, but via Google I did not get much source to reach an exact answer. A search on a few technical forum about the same discussion , but could not get what I was looking for , so I have typed in this forum to take this discussion further. The subject of discussion was about the conductivity of the heat sinks. I got a few replying that favors the copper one more than the aluminum. So I wanted to know you people review on this topic. Please share your ideas on this subject and let me know what do you say on the heat sink’s conductivity.
