SilverStone Heligon HE02: Monster Fanless CPU Cooler

Viewing page 2 of 6 pages. Previous 1 2 3 4 5 6 Next


The SilverStone Heligon HE02 is composed of a copper base, 6 x 6 mm thick copper heatpipes soldered to 30 aluminum fins, all nickel-plated by the looks of it. By our measurements, the heatsink is 160 mm tall (6.3 inches) but the effective height depends on how high the fans are mounted. According to our digital scale, it weighs approximately 990 grams (2.2 lb).

The HE02 is has an interesting look, octagonal with right angle corners instead of straight diagonal sides. There are also gaps at the center on two sides making it resemble an "H" with a expanded waistline. It doesn't look like a particularly effective air cooler as there is quite a bit of distance from the center to where fans can be mounted.

The fins are thick, measuring 0.52 mm wide with an ample 3.30 mm separation, presenting very little impedance to system airflow. To maximize its surface area, it's asymmetrical, particularly length-wise.

The narrower side is also uneven with three of the six heatpipes placed at a sharper angle, stretching the heatsink further toward one direction. Though it's difficult to tell from the image above, the fins are soldered to the heatpipes.

Unlike the Thermalright HR series, the fins are solid with no additional holes to provide extra ventilation.

The base was flat on one side and slightly concave on the other which isn't ideal in our experience. The surface has a dull finish with faint straight lines visible from the sanding process.
