heatsinks are very much the rage nowadays, more for the heat conducting
properties of copper, as well as its general good looks. Many of
the famous copper heatsinks include the Kanie Hedgehog, Thermalright
SK6 and the Globalwin CAK38, as well as the funky copper offerings
from Zalman Technologies.
contender which isn't that famous, coming from Akasa (Taiwan) Corp.
and Lapicon Electronics Ltd, the Akasa Silver Mountain, which looks
like a heavy duty heatsink covered in chrome, but is actually a
copper heatsink plated with silver.
Electronics Ltd. is part of the Akasa Group. The Akasa Group comprises
of Akasa (Taiwan) Corp. and Lapicon Electronics Ltd. The former
is based in Taipei, Taiwan and the latter in West London, UK. The
Group has manufacturing facilities in Taiwan and China.
plate the copper heatsink? More to do with the design of the heatsink,
it's pin fin structure is a result of the pin fins mounted onto
the copper base of the heatsink itself. The junction at where
the pins contact with the base doesn't offer the best heat conduction,
therefore the silver plating was designed to help address that
shortfall, where the silver plating covers up and fills in whatever
gaps there may be between the heatsink base and its fins. This
allows for better conduction of heat, and thus allowing the heatsink
to perform more consistently. This lack of optimum surface contact
area was a big problem with the Kanie Hedgehog 238M, where performance
of the heatsink sometimes differed greatly from sample to sample.
