Design and Functionality

At first glance, we see just another tower cooler, although this one is 170 mm tall:

But that is only the first impression. The heatsink weighs 806 grams and the layout below shows its dimensions:

Well, Thermalright Archon heatsink consists of 50 aluminum plates, each 0.5 mm thick, that sit on six heatpipes 6 mm in diameter. The heatpipes go through a copper base plate and all contact surfaces between the heatpipes and the base as well as the heatpipes and heatsink plates are soldered together. The entire heatsink is nickel-plated:


The gap between the heatsink plates is 2.0 mm. the calculated effective heatsink surface measures around 9,000 cm2, which is more than 2,500 cm2 smaller than by Silver Arrow (11,560 cm2), but a little bigger than by ThermoLab BARAM 2010 (8,900 cm2). The heatsink plates have four unique ledges on each side. There is also a uniquely shaped opening cut out in the very center of the heatsink:

At the same time the heatsink narrows down to 45 mm in its central part and widens up to 55 mm towards the ends. At this point we assume that all these shaping peculiarities are intended to reduce the fan airflow resistance and increase the ultimate cooling efficiency of the product.

The key peculiarity of Thermalright Archon is the way its heatpipes are laid out inside the heatsink body. As you can see in the photographs above, the heatpipes inside the heatsink are lined up in two rows and are spaced out at the same distance from one another, which should already ensure even heat distribution over the heatsink plates. Moreover, check out where these heatpipes come out of the base plate and where they go inside the heatsink:

We all know that central heatpipes heat most of all. And as you can see, Thermalright engineers made sure that these hottest heatpipes would be as far from one another as possible. This should ensure that the heat dissipation from the heatpipes to the heatsink occurs in the fastest and most effective way. Everything is very simple, but no other cooling solution maker has come up with anything like that before.

The thinnest part of the base plate where heatpipes lying inside special grooves are soldered to it is 3 mm:

The base plate contact surface is unevenly prominent, which is in fact quite typical of Thermalright products:

As for the finish quality, the base of Thermalright Archon cooler is impeccable:

Below you can see the thermal compound imprints on the cooler base from the CPU heat-spreader:

Thermalright Archon is equipped with one Thermalright TY-140 fan, which we have already reviewed before in our article called “140 mm Fan Roundup”. You can use rubber triangle pads and silicone strips with one sticky side to eliminate the vibrations transfer from the fan to Thermalright Archon heatsink. We learned by trial (and not error) that there are only two short segments along the sides of the fan that contact the heatsink. This is where we stuck the anti-vibration silicone strips:

The fan is attached to the heatsink using two wire clips included with the cooler. They go into the special retention holes in the heatsink and then need to be pushed until click to lock in the retention holes of the fan:

There are two sets of clips included with the cooler, so you may armor your Thermalright Archon cooler with two 140 mm or two 120 mm fans, if you wish.
