IHS, dunno, but some said copper
DIE, the die is using silicon + gemanium.
this two semiconductor making the wafer for all die.
ram is different bcause the packaging.
about thermo, heat dispassion rate is an important factor.
copper may absorb 400W/mk of energy, but how fast does it release?
yet we may see the comparison of xp-90 and xp90c.
i hope that may get a chance to test it, using different airflow and air pressure.
i believe that is the heatsink is good, it does not need to be full copper.
combination of copper + alu is great enough.
about nickel
90.9 W/(m·K) thermal conductivity
and
13.4 µm/(m·K) thermal expansion

QUOTE(MetalZone @ Jun 11 2006, 10:43 PM) Aleck as always, the WC guru.  There is no such thing as difference in heat absorbsion and heat dissipation. Thermal conductivity is thermal conductivity as it is, regardless in absorbing heat or releasing heat. The best metallic electricity and thermal conductor is silver. Not gold. In fact, copper has better electricity and thermal conductivity than gold. And yeah, the best thermal conductor is diamond. It is possible to make cultured diamonds, real ones, just not formed in a natural process. And its composition is even more pure than a natural diamond. So, yeah, you can make pretty large ones and make them into waterblocks or heatsinks  but on specific heat capacity. is alu>diamond>copper This post has been edited by Westley: Jun 12 2006, 12:22 AM |

aleck, that means water cooling, alu made radiator is much advance because of tech applied?
