Type of copper
I was just wondering if there is a stardard alloy of copper that is preferred, or if copper is copper. I am looking into making a waterblock for a design class and need to specify which type of copper I am going to use....

The purer the copprer the better the heat transfer so people try to use metal with the most amount of copper in. The copper people seem to use most is about 99.9% pure copper with the rest made up from small oxidation of the surface area.
Though to make the "best" you'll need silver (also pure). I know of no "super alloy" that conducts heat better than copper(or silver). Hope this helps ~ Boli

super alloy?
cusil ? look that up maybe...not quite a viable option though |

According to the place that I get my copper from, (Admiral Metals Surplus Outlet in Woburn, MA) There are two types of copper that are normally encountered. Regular Copper is very high purity, but contains a certain low amount of Oxygen in the metal's crystaline structure. "Oxygen Free" copper is made under special environmental conditions, and does not have the disolved Oxygen, but is significantly more expensive. The O2 free stuff is needed for certain specialized applications (I think I remember nuclear reactors, and certain types of chemical processing equipment)
From a thermal standpoint, the difference between them is supposed to be negligible. The Cu/Ag alloy Archmage was mentioning has been discussed many times before. I forget the exact numbers but the important thing is that it is WORSE than plain copper by a significant margin (though slightly better than Al) Thus Ag is still the theoretical best, though not by enough to really justify it's cost. It is followed closely by Cu, with Al a distant 3rd. Gooserider

I know that cooling these metals to extremely low tempatures has the obvious advantage of coolign the cpu significantly also but do these materials become thermal superconductors just like they become electrical superconductors at extremely low temps?

In most cases, alloys, even of two highly conductive metals tend not to have a very high conductivity, at least relative to that of its constituents. 8-ball

It's hardly relevant to Computer Cooling at any rate, as the temps involved are far lower than anything even a radical cooler is going to be able to reach reasonably. (I also could be mistaken, but I would expect that the conductivity changes at those temps might cause the CPU etc. to operate in non-acceptable ways...) Gooserider

But the impracticalties youve already mentioned, to get a noticeable increase in thermal conductivity you need a large drop in temps, larger than the average overclocker can produce... ]JR[ |

I presume these "lattive vibrations" get smaller and less violent because of the fact that time slows down at lower tempatures?

were in a forum about overclocking and cooling, the main concept why chip run faster when cooler is to do with lattice vibrations in the semiconductor... not sure if I can be bothered with this forum, too many llamas... ]JR[ |

hydrogen,
TIME does NOT slow down... the vibration or agitation level of molecules however does. This gives an overall appearance that everything is slowing down. Just not time. Time is constant unless you are approaching the speed of light. At this point it becomes a relative comparison... Back on topic: 99.9% pure copper is what I've been using as well. Works just fine. I have not had the opportunity (read: money) to spend on trying out the same blocks with Silver.
