on fin design of all Thermalright heatsinks is nothing new, and it is a
process that works well if done right. Each
roughly 0.35mm thick copper fins is stamped from sheet metal and then assembled
interlocking fin assembly
via little tabs and keys on the outer corners. The entire fin assembly is
then soldered to the copper base plate.
Providing the solder joint is thin, and complete,
the overall effect is very similar to having a full copper heatsink from tip to
base (but not exactly as thermally efficient).
Thermalright protect the heatsink base finish with a protective sticker, but
unfortunately it seems they may have been a little too zealous choosing the
adhesive, because as we pulled off the sticker, the glue stayed in place.
Suffice to say, it was a real chore to remove all that adhesive before even
being able to test out the Thermalright SK-7 heatsink.
Fans are held in place on the Thermalright SK-7 by means of two springy
wire clips. The clips hook into little tabs at each corner of the
copper base plate. With a fan in place on top of the fins, the clips
are positioned so that they lock into place in the small screw holes in the
fans' plastic frame. The system works pretty well, and makes it rather easy to
remove and swap out fans without the need for any tools.
The SK-7 comes with
four sets of these clips so that fans of 38mm, 25mm, or 15mm in height can be
used with the heatsink. Depending on the height of the fan you wish to use, one set or another of the clips
are necessary. A small set of foam stand offs are also included which you
can stick to the bottom of the heatsink to help prevent the silicon core from being chipped during
