Abstract: Just as quickly as Thermosonic's ThermoEngine entered the cooling market, it has since managed to
get itself into controversy.

Differences between the two varieties of
Thermoengine V60-4210 heatsink
| Hollow Thermoengine |
Solid Thermoengine |
|
|
|
| There is no real difference
between the outward appearance of the fans on each of the Thermoengine
heatsinks except for the number of fan blades.. In our testing the 9-blade
YS Tech fan (on the Hollow Thermoengine) offered better cooling
capabilities than the 7-blade T&T fan on the Solid Thermoengine. The
difference in performance between the two fans was about 3 degrees
Celsius.

| The aluminum heatsink
extrusions are exactly the same for each Thermoengine. The only
differences we could spot were between the patent numbers printed on the
corners, and the text on the fan shroud. The original (hollow)
Thermoengine has the following bits which appear to be absent from the
current retail versions: "Thermosonic Technology Inc," and "sink &
clip patent pend. world wide."

|
|
| Both of the heatsinks have
their bases finished with the same machining quality. From our
measurements the bases of each Thermoengine are perfectly flat. There are
some very small marks left over from the machining process, but
regardless, the base is fairly smooth.

The reason for much of the
controversy over the Thermoengine heatsink lies with the absence of the
top plug, shown on the original hollow Thermoengine on the left. The solid
Thermoengine on the right is without this feature.
The big question is whether
or not the hollow cylinder inside the Thermoengine has a significant
effect on the heatsinks' ability to cool. If the majority of the
Thermoengine's cooling effectiveness is drawn from the hollow cylinder
then its removal will have a substantial impact. If however, the
Thermoengine is mainly reliant upon its' unique aluminum extrusion, then
the effect of the absent hollow cylinder will be moot for the most
part.
|
| This image, over the top plug for the
hollow cylinder within the Thermoengine has been the center of much
speculation. Many people originally assumed that it contained an integral
heatpipe, a liquid, a phase change material, or some other chemical or
gaseous substance.
|
 |
| The current versions of the
Thermoengine in the retail channels appear to lack this fundamental
feature. Why it was removed are beyond the scope of this article, but we
will demonstrate the differences in temperatures by its
omission.
