I've got one! It's called the Silverado. Its about 2 ounces.

Unfortunately, its only for PIII's and older AMDs

Now that is funny. You take the small theoretical advantage silver might
have in heat dispersion, and then screw it onto an aluminum heat sink using
thermal paste!! Something about a chain being no stronger than its weakest
link comes to mind.... The worst of both worlds in this particular
design....

Kind of like an oil "cooled" engine then being cooled by water then being
cooled by air. It'll never happen!



The main reason is that there is no real advantage to it. Air is a
really poor heat transfer medium, so almost all of the temperature
drop is in the air. Changing from Aluminum to Silver might increase
the temperature of the heat sink surface by a few degrees, but that is
no real difference (although silver plating might look neat).

Hey I'm for stuff that looks cool, but you can't even see the silver on this
thing once it's installed!

Silver in air tanishes and eventually turns an uneven black.

This is no good design.
The purpose of the silver base is to transport the heat, horisontally,
to the aluminum cooling fins. This is sound thinking in itself. But
the big problem is that copper is so much better for this purpose than
silver. While I think this is a good opportunity to become cynical
about "reviews", the failure of this rather large heatsink to perform
is evident in the tests. Even so the reviewer seem to think "updated"
design could do something about this. Which illustrates the power
perceived properties have over peoples understanding of the world.
As I said, copper is superiour for this purpose. It can be fused to
the aluminum. It's heat conductivity is only 4% less than silver, but
due to both its lower weight and cost, we can make the base much
thicker in copper. Copper is also vastly superiour to silver in heat
capacity, making it much better in the role of 'buffer', or reservoir
of 'cooling'.

That's what we hire maids for, right?
