Design and Functionality

This newcomer is a tower cooler measuring 131x112.3x150.7 mm and weighing 775 g without the fan. Tuniq Tower 120 Extreme looks pretty unusual:



The cooler consists of five copper nickel-plated heatpipes with aluminum nickel-plated plates pressed tightly against them. There are 42 plates with a 29 mm gap in the center for the cooling fan:

The cooler heatsink is truly unique due to unusual shape of its plates. The plates edges are shaped like blunt cogs of a saw and the plates are slightly shifted away from one another. Therefore, the heatsink looks like fish scales:

Very unique, don’t you think so? But why did they do it this way? There is an opinion that it has been done to lower the airflow resistance and reduce the level of generated noise, but we tend to believe that the “scaled” heatsink design is merely an attraction for potential buyers.

The heatsink plates are 0.4-0.45 mm thick and are spaced out at a little less than 2 mm from one another. The sides of the heatsink are sealed with the plate edges bent downwards:


As I have already mentioned above, the cooler is built on five heatpipes. Three of them are 8 mm in diameter and the remaining two – 6 mm. Note that the heatpipes of different diameter alternate:

The top of the cooler is covered with a decorative cap with a fan attached to it. There is a universal retention plate already attached to the bottom of the heatsink:


The aluminum inserts between the heatpipes in the base of the cooler are only 1.5 mm thick. The contact base surface is very even and is very well finished for a cooler with Core-Contact technology:

Here are the thermal compound imprints on the cooler base that we got from AMD Phenom II X4 (left) and Intel Core i7 (right):

Although these imprints look quite different, don’t be surprised. The thing is that we used Tuniq TX-3 thermal compound for the left imprint and Arctic Silver 5 for the right one. However, during our test session the cooler was used with the same Tuniq TX-3 thermal interface on both platforms.

There is a seven-blade 120x120x25 mm fan made of clear plastic inside the Tuniq Tower 120 Extreme heatsink. It is fastened in a metal frame:


You can adjust the rotation speed of this fan using the included variable-speed controller that can be installed on to the back panel of your system case. It allows changing the fan rotation speed from 1000 to 2000 RPM. In this case the fan should generated between 16 and 20 dBA of noise and create 90.65 CFM maximum airflow.

According to the sticker on the fan rotor, it uses a magnetic fluid dynamic bearing (MFDB). Its MTBF is claimed to be 50,000 hours or over 5.7 years of non-stop operation.


The fan rotor is 40 mm in diameter. The fan comes with a 600 mm cable. There are blue LEDs in the corners of the fan frame, which produce very pleasant mild glow in the dark:

However, when the fan is inside the heatsink, you can only see the LED lighting at the bottom of the cooler.
