Design and Functionality
If you are familiar with the previous model – Accelero Twin Turbo, you will notice that the Pro-version is very similar to it:
However, although the new cooler maintains the same length, it became 48 mm taller and 15 mm wider. Its weight has increased from 350 to 450 g.
This product still consists of four copper heatpipes 6 mm in diameter that come out of the copper base. They hold an array of aluminum heatsink plates pressed firmly against them. There is a plastic frame with two fans sitting on top of the heatsink. Here are the detailed dimensions of the Accelero Twin Turbo Pro cooler:
It is very convenient that the manufacturer provides detailed cooler dimensions , because it will make it very easy to determine whether Accelero Twin Turbo Pro would be compatible with any of the graphics cards the potential buyers have in mind.
The heatsink has “grown” five plates bigger: now there are 35 plates in the array. The plates have also become thicker: 0.5 mm instead of 0.25-0.3 mm. The heatsink has also become denser: the gaps between the plates have been reduced from 2.5 to 2.1 mm.
So, Twin Turbo Pro now has relatively large effective heatsink surface for a VGA cooler: it equals 4080 cm2. I also have to point out to you that the heatpipes in the new cooler are now arranged in different direction: they come out of the base and head straight up and pierce the heatsink from the top towards the bottom. Before they used to come out of the base and head down and then go through the heatsink array from the bottom towards the top of the array. The new cooler will obviously have no compatibility issues with the graphics, which GPU chip is located closer to the lower edge of the PCB. I also have to add that the heatpipes are soldered to the grooves in the base plate.
The plastic frame with the fans is attached to the heatsink with two side clips:
It sits very tightly on the heatsink and is pretty hard – though possible - to remove:
Another evolutionary modification is the use of two 92 mm fans on Accelero Twin Turbo Pro instead of two 80 mm fans used before:
The rotation speed of these 11-bllade fans varies automatically depending on the graphics card load and the GPU temperature in the interval from 1000 to 2000 (±10%) RPM creating a 54 CFM airflow. The noise, which Arctic Cooling usually declares in Sones is claimed to be 0.2 ~ 0.6 Sone, which is exactly what the noise level of the previous Twin Turbo model was. The maximum fan power consumption shouldn’t exceed 3.6 W. Unfortunately, we do not know the life span of their fluid dynamic bearings.
The cooler base is covered with a rather thick layer of highly efficient Arctic Cooling MX-2 thermal interface:
The cooler base is very even, no issues here. However, the finish quality could have been better.
