The Corator DS is a large (155mm x 140mm x 121mm) heatsink that uses two symmetrical tower fin arrays that are interconnected via a series of four 8mm copper heat-pipes. These heat-pipes run along the contact surface of the heatsink to gain the most efficiency possible from the heat-pipes. Coolink has called this Gapless Direct Touch technology. The Gapless part comes from the fact that the gaps between the heat-pipes are filled with copper so you have a single surface. Much like the Noctua NH-D14, this cooler uses a fan in between the towers, but in this instance you only have a single fan dissipation heat. When you look at the top of the fin arrays you can see dimples all the way around the fins which can serve as a way to break up airflow for more turbulence to increase cooling capacity, or can be purely for looks.
The Gapless Direct Touch Technology has the spaces between the heat-pipes filled with copper instead of aluminum to provide the same thermal conductivity across the contact patch. This design has its merits, but was a little rough in the execution. A little bit of a lap job to clean it up would surely pay cooling dividends. Sticking out like wings are the mounting screws. These are locked into a single plate that screws into the top of the heatsink base.
The SWiF2-120P fan mounts in the center of the two towers of the Corator DS and is held in place by a series of clips. These attach on the outside of the heatsink and then swing in to latch into the screw holes on the fan. This arrangement is fairly easy to use and securely mounts the fan. Coolink has taken a page out of the Noctua book by including vibration dampening strips mounted to the tower to keep the vibration from the fan in check.
Coolink has included a single SWiF2-120P fan. This fan is a PWM controlled fan that runs from 800 to 1700 RPM pushing between 37 and 75 CFM. For those flow numbers you really don't have to pay a noise penalty with the maximum acoustical noise coming in at 27.1 dBA. The SWiF2-120P fan uses a hydrodynamic bearing to keep actual fan noise down as well as improve the life span of the fan.
Looking at the specs and features of this heatsink from Coolink, I have got to say it looks like it should have the ability to keep an overclocked 920 in check. Let's see if it can.
