With the setup, we can easily answer the question - is Direct
Die a better performer than Copper?
Unlike a heatsink where they will use the same fan so results can possibly
be compared, with a block there is the difference of PUMPS. And seeing as I
use a lower powered Senfu and other reviews use much higher rates pumps this
made Direct Die look bad. Which is why we compare together now with the same
pumps..

Note. Due to an update to the "Radiate" software,
it would seem the original Direct Die was more effecient than though as it now
has a 0.10 C/W instead of a 0.12. Infact the Duron gives out more heat than
thought!
I think the results say a lot. But the main thing here is the fact a duron
is HARDER to cool due to the smaller die size. Direct die doesn't seem to care
and is just as effecient with either size! copper on the other hand DOES as
you can see the Danger Den having temps almost DOUBLE that of the D2D. Although
the difference is not so large with the Tbird, as chips get hotter I think the
gap will widen.
So the Danger Den is a nice block, and at the momment has a big up on Direct
Die - Attatchment. But rest assured this is also being worked on.
Conclusion
Direct Die rocks, but is a power not many people have yet harnessed. Stay tuned
as we develop this technology further.
