Design and Functionality

So, we see a not very traditional tower heatsink measuring 126x63x150 mm and weighing 750 g:


Six copper nickel-plated heatpipes 6 mm in diameter are soldered to the copper nickel-plated base. They hold 65 aluminum plates of pretty unique shape:


The unique thing about CoolAge X120TF heatsink is the so-called honeycomb structure of the heatsink array, which was created by pressing two neighboring plates against one another. The plates are profiled in such a way that they create honeycomb shaped cells when pressed against one another:


As a result, we see a very dense array of 0.4 mm plates with variable gaps between them ranging from 0.2 to 0.4 mm. CoolAge call this technology “Wind Tunnel” and believe that in this case heatsink plates form a lot of channels for uninterrupted and efficient airflow.

As you may see, the contact spots between two heatsink plates form about 0.8 mm of metal. So, we assume that far not every heatsink will be able to push the airflow through such a dense structure successfully, which means CoolAge X120TF is very unlikely to perform efficiently in quiet fan modes.

Besides the uniquely shaped heatsink plates CoolAge X120TF heatsink also uses non-linearly distributed heatpipes. Moreover, the heatpipes are lined up in two rows on each side of the heatsink forming kind of a wedge along the airflow direction:


CoolAge doesn’t specify why they decided on this particular heatpipes placement that is why we can only suppose that this has been done not only for more even heat distribution over the heatsink plates, but also for lowering the airflow resistance. Overall, CoolAge X120TF heatsink reminds us of the Thermalright Ultra-120 eXtreme (not only by its design but also by the color of the metal parts).

The heatpipes lie in special grooves cut out in the cooler base where the minimal plate thickness beneath the heatpipe makes 2 mm. the contact surfaces between the heatpipes and the base plate are soldered together. The base surface finish is of pretty high quality although it hasn’t been polished:

Unfortunately, we can’t say the same about its evenness:


It is obvious that the base is slightly curved in two spots and you can see the result of this curving on the thermal compound imprint photo below:

We didn’t even out the base plate before the actual performance tests and used the cooler as is.
