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 additionally.

TI-S8640N Heatsink From All Angles
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.

Heatsink Top:
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.

Side A:
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 the fins.
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 days.
Heatsink Base:
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.
