The second unique peculiarity of the new Corator DS cooler is its base that uses G.D.T. (Gapless Direct Touch) technology:

In fact, it is a direct-touch base, where the heatpipes contact the CPU heat-spreader directly and not through the copper base plate. However, G.D.T. technology differs from the HDT technology that we are very well familiar with by the absence of a solid aluminum insert between the heatpipes. In this case it has been replaced with four individual solid copper inserts:

The base surface is very even and is finished perfectly for a direct-touch type of a base. You also notice that the heatpipes in the base are somewhat thicker, which looks very much like soldered additional copper plates, but we didn’t find any traces of soldering or thermal glue to support this assumption. I would also like to point out that although Corator DS uses 8 mm copper heatpipes, they narrow to 5.5-6.0 mm in the base and the 5 mm gap between them is completely filled with the above mentioned copper inserts:


We cannot complain about the quality of the thermal compound imprint left by the processor heat-spreader on the cooler base. Here we can clearly see copper pipes and inserts, which create an illusion that the base is built of seven copper heatpipes 5-6 mm in diameter that are pressed against one another. Unfortunately, this isn’t the case.

Coolink Corator DS cooler comes equipped with one 120x120x25 mm fan featuring eleven acid-green blades:

The fan is also made by Coolink. It is modelSWiF2-120P that came to replace the older SWiF fans.


According to the specifications, the fan is pulse-width modulation (PWM) controlled in the interval from 800 to 1700 (±10%) RPM. At these speeds SWiF2-120P creates 35.55-75-10 CFM airflow and generates 8.5-27.1 dBA of noise. The fan specs do not mention the lifespan of the fluid dynamic bearing inside, but we do know that the maximum power consumption of this fan shouldn’t exceed 4 W:

SWiF2-120P rotor is 41 mm in diameter and the fan power cable is 400 mm long.

The fan is attached to the heatsink with two wire clips that should be inserted into special grooves in the heatsink arrays:

The fan frame contacts the heatsink through two special silicone strips stuck to the inside of one of the arrays. Unfortunately, there were no wire clips and silicone strips for the second fan included with the Corator DS cooler. Even if the second fan doesn’t contribute much to the cooling efficiency improvement, it would still be nice to have an extra fan retention kit, just as a token of the maker’s good will. Especially, since they really cost pennies.
