Design and Functionality

The tower-type heatsink of these coolers consists of aluminum fins, six copper 6mm heat pipes, and a copper base and has a small auxiliary heatsink above the base.

 

 

Save for the sole of the base, the heatsink and heat pipes are all nickel-plated, so the coolers look pretty enough.

Each cooler measures 138x99x158 millimeters. The heatsink is only 74 millimeters thick.

Alpenföhn and Deep Cool disagree in specifying the weight of these products. The former company says 1062 grams and the latter, 1189 grams. The heatsink feels heavy indeed. The Baram-2010 seems only half as heavy, for example.

The heatsink consists of 48 aluminum fins (one of which is for decoration only) press-fitted on the heat pipes at a distance of 2 millimeters from each other. The fins are 0.5 to 0.55 millimeters thick.

 

The heatsink seems to have two types of fins at first sight. However, they are actually identical, but wedge-shaped and alternating. As a result, the edges of the fins are shifted relative to each other, reducing the resistance to air flow and improving the cooler’s performance at low speeds of the fan(s). The heatsink is symmetrical. Its sides are covered in the middle part by the curved-in edges of the fins. These edges are kind of pressed into the heatsink, increasing the pressure inside and focusing the air flow on the heat pipes.

 

There is only one difference between the heatsinks from Alpenföhn and Deep Cool. It is the logo on the top fin.

We guess this fact cannot affect their performance, yet we will compare the two heatsinks anyway.

The six heat pipes are shifted relative to each other in the heatsink body:

The heat is distributed more uniformly in the fins as the result. Except for the top one, the fins are perforated in the center. There are four square holes in each fin and also four round openings with a diameter of 2.5-3 millimeters (these must have been used during the manufacturing process).

The copper base measures 40x50 millimeters and has a minimum thickness of 3 millimeters. It is ideally flat and perfectly finished:

The convex heat-spreader of our CPU left an irregular footprint on the cooler’s sole, just as expected.

Each cooler is equipped with a 9-blade Föhn120 Wing Boost fan. The original manufacturer of the fan is EKL AG (the DF1202512CL-007 model).

 

You can only tell the fans apart by the stickers. The sticker on the Gamer Storm offers but a minimum of information:

 

A distinguishing feature of the fan is its rubber frame. In fact, the impeller is secured on the four poles of the plastic ring, and a stiff rubber casing is press-fitted on it from above.

This is how the manufacturer solved the problem of suppressing vibrations from the fan to the heatsink. Judging by the fan specs, the Alpenföhn Matterhorn and Deep Cool Gamer Storm are targeted at users who appreciate silent computers. For example, the speed range of both fans is 500-1500 RPM at a noise level of 8 to 24.8 dBA (Alpenföhn) and 17.6 to 27.6 dBA (Deep Cool). The specified airflow differs somewhat: 63.6 and 66.3 CFM, respectively. Still, we have no doubts that this is one and the same fan model. The service life of its fluid dynamic bearing is 30 thousand hours. The peak power consumption is 1.56 watts. The impeller is 110 millimeters and the rotor is 40 millimeter in diameter. The cable is 420 millimeters long.

Four wire brackets are included with each cooler, so you can install a pair of fans on each heatsink. The brackets are inserted under the top fin of the heatsink.

Thus, the fans are somewhat below the top fin. It is easy to hook the brackets up as well as to undo them.
