The specs on the P366 specify a Sunon 60mm x 25mm fan, but
we were pleasantly surprised to find a YS Tech instead.
The fan is very quiet but powerful enough to send lots of
cool air down through the copper fins which are spaced 2mm
apart.

When we say the Neng Tyi P366 is a sold copper heat sink
we mean just that. Apart from the clip, and fan everything on this little
guy is copper.
While the fins are bonded to the 3mm thick copper base,
we're not sure if they are soldered or glued in some fashion. The joint
appears to be good enough for thermal conduction as would be
expected.

Without the fan attached its a bit
easier to see how Neng Tyi assembles their copper fins into one large
assembly. Small tabs are folded over to create on interlocking unit out of
many individual copper fins.
Also note the nice big thumb lever
for the clip - it does a good job making clipping a lot
easier.

At first glance we were a bit weary of the base of this
copper cooler. But despite our first impressions the area which makes
contact wit the processor was perfectly flat.
For our tests we removed the Bergquist pad, which
resulted in about a 1 degree drop in
temperature.

About the only fault we can find with the the
Neng Tyi P366 revolves around the side copper shroud. It would serve as a better
cooling surface if it made closer contact with the copper base.
As it stands
currently, two small tabs on each side of the
base lock the shroud into place, but they still don't make very close contact with it. If
the shroud edges were soldered or thermally bonded (epoxy for example) it would
add yet another path for heat transmission, and probably boost cooling performance
by a degree or so further.
Anyhow it's a small factor, let's take a look now at how
this copper heat sink stood up to the venerable Super Orb on the
Frosty Synthetic Temperature Test platform...
