Yeah, it's far from the normal type sink you see in PC's. So ... do you like it?
Mind you, those are just early prototypes to iron out some design & production issues.
By far the most time was consumed by working the small billets into usable
sheets. Just found out my "toolgirl" friend has access to 110 Copper flat stock at cost where she works.
Which should make the production process a lot easier. No need to go from
molten puddles.
The next generation of sinks will be more elaborate. And no solder either.
I always knew solder was a poor thermal conductor. But this info source makes me think
it's much worse than I thought.

Hard solder only
94 W/c-m??
And I highly doubt makers like Thermalright use "hard solder". Most likely some
kind of "easy9soft) solder" with a low melting point.
Using pure Silver as the joining medium should me much, MUCH better.
