Just as quickly as Thermosonic´s ThermoEngine entered the cooling market, it has since managed to get itself into controversy. The controversy stemmed from apparent differences between the Thermoengine heatsinks being circulated around the hardware review community, and those available for sale on the retail level. Since a lot of the interest in the Thermoengine heatsink surrounded the hollow center core, suspicions were aroused when retail units started popping up with solid cores.

The evolution of a product is nothing new, and even though the differences between the two types of Thermoengine raised a lot of questions, the only real question is "does this even make a difference in terms of cooling"? This also happens to be the only question we can really answer about the change in the Thermoengine´s design, and one that we will be putting to rest in a few moments.
