| Thermalright SK6 Perspectives|
Delta fan is known for two things; being fast, and being loud. In this
case we mounted the Delta in an impingement fashion
so the air was blowing down into the many thin copper fins -
yielding the best cooling possible. The seven-bladed Delta connects directly to the
motherboard fan headers and has a lead wire to monitor RPM which
the manufacturer lists at around 6800RPM.
are 36 sets of thin copper fins on the SK6. Each fin measures about
0.5mm thick and roughly 30x22mm in size. The fins each have a small copper
fold on the base 1mm in width that allows them to be soldered to the copper base. We've seen some other heatsinks that used different forms of adhesives with generally less than great results. The thermal interface between the fins and the base is the most critical so it is important to have a solid connection.
the copper fins all have an angled edge. That angle ends up forming a small area of material for the 60mm fan to sit comfortably in. The heatsink sits in at about 31mm tall.
The base is relief cut by 7mm and the clip channel is
also 7mm in width. You can see evidence of the soldering by the base of
the right fin.
Looking at the other side you can see the basic
fin structure that has gone into making this heatsink. Each fin is
identical to another
and is stamped from a sheet of copper.The base of the cooler is notched out 7mm to make space
for the socket cam arm.
main portion of the base measures 57x50mm, but if we measure the entire
area is sits in at 64x58mm. As we mentioned before the base is very flat,
but the surface finish is less than perfectly smooth. A little bit of
lapping would go a long way to make this heatsink a true force to
be reckoned with. Notice the four tabs that the spring clips hook
into to hold the fan in place
