Coolink Corator DS CPU Cooler Review
By Rafael Coelho on April 21, 2010
This time we tested Corador DS CPU cooler from Coolink, which uses a "sandwich" design, with two tower heatsinks, four U-shaped heatpipes and one 120 mm fan. Check it out!
Corator DS box is big and simple, with a picture of the cooler and some information about it, as you can see in Figure 1.
Inside the box we found the cooler with the fan already installed, user manual, installation hardware and a tube of thermal compound.
In Figure 3 you can have a general view of the cooler. We have already seen this design on other coolers, like Tuniq Tower 120 Extreme, Zalman CNPS9900 NT and Thermaltake ISGC-200, with excellent performance on the first two. This fact, along with the huge size and good general aspect of Corator DS, gave us great expectations about its performance.
In Figure 4, you can see the cooler from the front side. Through the fins you can get a glimpse of the green fan, as well as the four well-distributed heatpipes.
In Figure 5 you have a side look of the cooler, where you can check the two-heatsink design. Note how they are not identical: the rear heatsink (where the fan is attached to) has more fins than the front one.
In Figure 6 you can check the rear heatsink. The manual especifically says to install the fan pushing the air on this heatsink.
In Figure 7 you can notice that even with different heatsinks the shape of the fins is the same.
In Figure 8, you can see the base of the cooler. At first sight it seems to be made by a copper plate that covers the heatpipes, but looking carefully we noticed that this base is made by the heatpipes itselves. However, unlike what happens on Nexus VCT-9000, the gap between the heatpipes is filled with copper pieces that fit them perfectly, turning the base into something that looks like a one-piece copper block, which is good: besides having more contact area with the CPU, the heat (mostly generated at the center of the CPU) can be better delivered to the outer heatpipes. If this base was better polished, it would be close to perfection.
In Figure 9, you can see the heatsink without the fan. Actually, you need to remove it in order to install the cooler, because it is necessary to fasten the screws located at the base of the cooler.
In Figure 10 you can notice one of the silicone stripes at the points where the fan touches the heatsink, which helps to absorb the vibration produced by the fan.
In Figure 11, you can see the fan used with Corator DS. It has 11 yellow/green turbine-shaped blades. The four-pin mini conector shows it has PWM automatic speed control.
In Figure 12, you can see the Chillaramic thermal compound tube which comes with Corator DS. This compound uses ceramic nano-particles.
In Figure 13, you can see the installation hardware used for Intel processors. The X-shaped mettalic backplate must be used on the solder side of the motherboard, assuring a simple yet very firm installation.
In Figure 14 you can check the holders installed on the motherboard. They are simple to install and do not bend the motherboard. After that, you just need to apply thermal compound, put the cooler over the CPU and fasten both screws.
In Figure 15 you can check the cooler installed on our motherboard, but still without the fan.
In Figure 16, you can see the fan in place.
In Figure 17, you can see the cooler inside our case. Even being a huge cooler, it did not interfere with any motherboard component nor obstruct the memory sockets.
We are adopting the following methodology for our CPU cooler reviews.
First, we chose the CPU with the highest TDP (Thermal Design Power) we had available, a Core 2 Extreme QX6850, which has a 130 W TDP. The choice for a CPU with a high TDP is obvious. To measure the efficiency of the tested cooler, we need a processor that gets very hot. This CPU works by default at 3.0 GHz, but we overclocked it to 3.33 GHz, in order to heat it as much as possible.
We took noise and temperature measurements with the CPU idle and under full load. In order to achieve 100% CPU load on the four processing cores we ran Prime95 with the "In-place Large FFTs" option, and three instances of the StressCPU program, all at the same time.
We also compared the reviewed cooler to the Intel stock cooler (with copper base), which comes with the processor we used, and also with some other coolers we have tested using the same methodology.
Temperature measurements were taken with a digital thermometer, with the sensor touching the base of the cooler, and also with the core temperature reading (given by the CPU thermal sensor) from the from the SpeedFan program, using an arithmetic average of the four core temperature readings.
The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed 4" (10 cm) from the fan. We turned off the video board cooler so it wouldn't interfere with the results, but this measurement is only for comparative purposes, because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which is not the case here.
We adopted a 2 °C error margin, i.e., temperature differences below 2 °C are considered irrelevant.
On the tables below you can see our results. We ran the same tests with the coolers shown on below tables. Each test ran with the CPU idle and then with the CPU fully loaded. On BigTyp 14Pro, TMG IA1, NH-U12P and ISGC-300 the tests were done with the fan at full speed and at minimum speed. The other coolers were connected directly to the motherboard and it controls the fan speed based on CPU load level and temperature on PWM models. ISGC-400, iCEAGE Prima Boss, Megahalems Rev. B, Thermaltake SpinQ VT, Zalman CNPS10X Flex, Tuniq Tower 120 Extreme and Tuniq Propeller 120 were tested at minimum speed on idle test and at maximum speed on full load test.

Coolink Corator DS main features are:
Coolink Corator DS is a good cooler. At first it impressed us by its size, weight and construction quality. It looks nice, but we don't think that "sandwich" coolers are the most beautiful ones.
Talking about noise, it is on an average category, quiet when the CPU is idle and a little noisy when it is under full load.
Its cooling performance is not bad, but does not compete with the most effective coolers we tested so far. As it looks (and costs) like a top-shelf cooler, we were a little disapointed with its performance.
There are CPU coolers with better cost/benefit options out there, but if you want a good and big cooler, you can buy Corator DS with no fear. Therefore it receives our Hardware Secrets Bronze Award.
