I was looking for information on materials for extruded heat sinks and came up to a thread here, I got curious (as I always do) and started navigating through the threads, I love it, I wanted In.
I really have no recollection to where I stumbled across this forum... I just can't recall... I'd guess I was searching the web from a specific item or similar and just accidentally stumbled on a link...
One of the members in mechanical-engg.com posted the link to an article, and i found it very interesting.
