Design and Functionality

At first glance, Coolink Corator DS seems to remind us of Thermalright IFX-14. Moreover, it looks remarkably similar to the popular super-cooler from Thermalright:



It looks like the design when there are two aluminum heatsink arrays pierced with four 8 mm copper heatpipes and a fan installed between them turns a classical approach to the best air coolers out there. Corator DS is the fifth cooler already that intends to become one of the best.

The new solution weighs a little over a kilo – 1040 g- and measures 121 x 140 x 155 mm:

However, things are not as simple as they may have seemed at first glance. The thing is that one of the unique peculiarities of the new Corator DS cooler is the use of assymetrical heatsink arrays. The first array to heat the airflow consists of 30 aluminum plates spaced out at 3 mm from one another, while the second array that receives the airflow from the fan features 40 plates with 2 mm gaps. You can easily notice the difference between these two arrays on the photo on the right:


In our opinion, this approach to heatsink design makes a lot of sense and should lower the heatsink resistance on the way of the airflow going towards the fan, which keeps Corator DS efficient even at low fan rotation speeds. And at the side that receives airflow from the fan where the fan static pressure is higher than on the air intake side, the heatsink is denser, which increases its effective cooling surface size and improves the cooler efficiency.

However, Coolink engineers didn’t stop at creating an asymmetric heatsink. If you take a closer look at the heatsink plates, you can notice that they have embossed dots that create additional turbulence for the airflow and therefore improve the heat transfer. Moreover, the middle part of the inside of the heatsink plates has comb-like edge pattern about 2 mm deep:

It also lowers the heatsink resistance to the airflow from the fan and maintains high cooling efficiency at low fan rotation speeds. I would also like to add that the heatsink plates are 0.5 mm thick and they are pressed firmly against copper heatpipes.

The smallest gap between the Corator DS heatsink arrays is 26 mm that is why you won’t be able to fit any thick fans in-between the heatsink arrays without damaging the cooler.


Heatpipes pierce the heatsink arrays in a straight line, but they are slightly spaced out in two pairs away from the center of the heatsink where you see Coolink company logo:
