Thermal Integration TI-S8640N Heatsink Review
There are three
sets of coolers in the Thermal Integration heatsink line-up. This series comes without
the signature copper core and a slightly larger dimensional size. The speedy little fan should make up for some of the slack where copper is no longer present.
Just to clarify things, the actual model number of this heatsink is TI-S8640N. The same heatsink
body is also available with a 10mm (TI-SI8640K), or a 15mm (TIS8640L) thick fan

||The Fan: |
A wire fan grill protects the
intake of this YS Tech fan, and keeps wires, fingers, and small cables from
easily getting sucked in. The Dr. Thermal logo is being branded by
Thermal Integration, rather than their much longer name by the looks of
it. The fan is 60mm wide and measures 25mm
thick. Power comes from a Molex pass through, and RPM signals go directly to
the motherboard. The fan draws just over 5W of power.
The top, the bottom, each is almost exactly
identical in this unique adaptation of an extrusion heatsink. The central area is
about 23mm square, and the fins are roughly 1mm thick. Each
of the fins are curved to one side,
and are spaced ~3mm for good airflow. Unlike the TI-V77L, the TI-S86
is only designed to accept 60mm fans.
The level puts added force under the
clip this improving the tension on the core of the processor for
better heat transmission. The difference is only a millimeter or so, but helps the stainless
steel clip go on easier during installation. The small fan shroud is really just
there to act as a stand-off for the fan, and secondarily to direct air-flow down through
||Side B: |
The clip is a bit more complex in
appearance then we
remembered the TI-V77L was, but essentially does the exact same
thing. The heatsink itself is installed by use of a small
flat head screw driver - a fairly common situation for heatsinks these
Base finish is very flat, but not exactly shiny or polished
to a mirror finish. Rather, the smooth base has a matte appearance to it.
Out of the box, the heatsink comes with a grey thermal pad that works fairly well. We tend to side with ceramic compound these days,
and that is what we used in our test of this cooler.
