Top Tier CPU Air Coolers Q3 2015: 9-Way Roundup Review

The SilentiumPC Grandis XE1236

SilentiumPC is a Polish company that is fairly well known in Europe, yet with virtually no presence in the North American markets. The company was founded in 2007, aiming to provide a wide variety of cooling and case solutions at competitive prices. For the means of this review, SilentiumPC provided us with the Grandis XE1236, which currently is the best cooler the company produces.

The Grandis is supplied in an aesthetically plain but effective cardboard box. There is nothing of note regarding the appearance of the packaging, as the only artwork is a picture of the cooler itself. It does offer good shipping protection though, with the cooler protected inside a clear plastic shell and the bundled items grouped in secondary cardboard boxes.

With the company focused on minimizing the costs, we did not expect the bundle of the Grandis to be grand. Nevertheless, besides the necessary mounting hardware and wire clips for three fans, SilentiumPC provides a tube of quality Pactum PT-1 thermal compound and a Y 4-pin fan power splitter. A small wrench tool is also provided, necessary for the installation of the cooler.

The Grandis is supplied with two 120 mm cooling fans. Both fans are mechanically and electrically identical, with black solid frames and tinted black blades. They have been rebranded and it is difficult to recognize their OEM. Their electrical specifications, speed and sleeving type match the Power Logic PL12S12L, yet the acoustic ratings are worlds apart.

The Grandis XE1236 is a symmetric dual tower CPU cooler, with relatively narrow towers for its class. The fins of both towers are perfectly symmetric as well, meaning that both their front and rear sides are identical, mostly straight with shallow indentations near their center. SilentiumPC died the top fin black, obviously for aesthetic purposes only, but it does not cover the copper heatpipes.

Up to three 120 mm cooling fans can be installed on the Grandis, using the provided wire clips. The wire clips are strangely shaped and very wide, expanding above and below the cooling fans. This makes them flimsy and prevents the movement of the front fan upwards to offer clearance for the RAM modules, if necessary. The center fan will have to be removed for the installation of the cooler, as there are no holes for a screwdriver. Do note that a Philips PH2 screwdriver with a shank longer than 145 mm is necessary for the installation of the Grandis, which is not supplied.

The base of the Grandis XE1236 is about as simple as the rest of the cooler is. It is split into two parts: the narrow lower copper part serves as the contact surface and the aluminum/steel top part provides mechanical cohesion and retention. Six 6 mm copper heatpipes expand from the base of the cooler to either tower on both sides, evenly spaced at the right and the left half of each tower. In order to keep the costs down, SilentiumPC did not plate the copper parts of the Grandis. The quality of the contact surface is disappointing, not because it has not been polished at all but because there are multiple machining marks visible with the naked eye and easily feelable by touch.
