CPU cooling system SilentiumPC Grandis XE1236 V2: review and testing

The users who watch the market for computer components must have noticed the dominance of predominantly Asian players. But there only a few companies with European roots with products on the shelves of local stores. It is very pleased to notice the desire of little-known companies in our area with the aim to promote their solutions in our market. After all, a healthy competition among manufacturers is only a good factor.

The Polish company SilentiumPC which is quite successful at home and won the West European market during last 8 years also wants to add own products to the shelves of the stores.  

And the range and approach the manufacturer to create products is worthy of particular attention. The SilentiumPC bet on as the functional components of good value and capabilities ratio. The latter is achieved by cheap box and reduction of the supplied set. So the buyer does not overpay for unneeded components and expensive package.

At the moment, the assortment includes a manufacturer of power supplies from 500 to 700 W, cases of a variety of sizes and form factors, laptops stands, fans ranging in size from 40 to 140 mm, and a variety of accessories. And today we have a representative of range of CPU cooling systems, which currently includes 6 models, quite diverse in terms of size and capacity of cooling. Meet a top cooler SilentiumPC Grandis XE1236 V2.

SilentiumPC Grandis XE1236 V2

Novelty has a two-tower layout and uses in its design a pair of fans with fairly low speed, which should provide excellent noise performance. Is this true, and can the test solution to compete with models from the more well-known manufacturers visited previously in our lab will be described below.

Sidewall shows us different angles of the cooler, and indicates the address in terms of the import and distribution in Poland, not hiding the fact that the device is made in China.

The back side contains QR-codes to install the new item on different platforms. Also there is a packaging of SilentiumPC Grandis XE1236 V2 in three languages (English, German and Polish) that describes the most notable features:

  • construction with double radiator provides a large area of heat transfer;
  • mounting system ensures compatibility with a number of current platforms for processors AMD and Intel;
  • use of a copper heat spreader and six U-shaped heat pipes 6 mm in diameter;
  • height of 158 mm makes the product compatible with most modern ATX cases;
  • the use of two 120 mm PWM-controlled fans with the ability to install third fan;
  • the use of reinforcement plates;
  • availability of complete high-performance thermal grease Pactum PT-1.

Component and side fan are stored in separate carton box. Packaging is quite heavy and contains everything needed to install the cooling system:

  • universal extender plate;
  • four anti-vibration mounts, studs and metal fasteners for different platforms;
  • set of goals and racks;
  • set of brackets for fans;
  • thermal grease in the syringe;
  • wrench;
  • adapter to connect two fans to each socket;
  • installation guide.

Do note that the supplied set contains three pairs of brackets for fans: two can be seen in the picture, and another is mounted inside the spinner, originally mounted on the radiator. We would like to draw your attention to the manufacturer's care about such details as the power adapter for the fans and the wrench for easy installation. And, of course, there is a detailed installation manual.

Design and structure

SilentiumPC Grandis XE1236 V2

 

SilentiumPC Grandis XE1236 V2

 

SilentiumPC Grandis XE1236 V2 consists of two section-towers, based on six U-shaped copper heat pipes with a diameter of 6 mm. Radiator plates are made of aluminum and have a thickness of 0.45 mm and are arranged relatively densely: at a distance of 1.8 mm from each other. Therefore, there is a sufficiently large number: 47 per each of the tower. Manufacturer’s approach in this case is quite logical, because the more plates, the greater the heat transfer area, hence the efficiency of the cooler is higher.

SilentiumPC Grandis XE1236 V2

The pipes are arranged in a row, which is natural given the small width of the radiator sections. The top plate has black color that harmonizes well with unpainted copper tube tips. There is the logo of the manufacturer, not allowing to confuse novelty with solutions from other companies.

SilentiumPC Grandis XE1236 V2

Between the sections you will have an access to the mounting plate, initially screwed to the base. It is secured by a screw with a raised head, which can be unscrewed using a long screwdriver (length 150 mm).

Heatpipes in SilentiumPC Grandis XE1236 V2 are not covered with a layer of nickel, therefore, the surface is more subjected to oxidation and some loss of thermal conductivity. The pipes are soldered to the bottom that will well affect the transfer of heat, but the plates are strung on them without the use of solder.

SilentiumPC Grandis XE1236 V2

The base is also not covered by a layer of nickel. During polishing the manufacturer did not set a goal to get a mirror image, but tried to ensure the highest level surface that he was quite successful. Base dimensions are 38 x 48 mm.

To actively remove heat from the radiator there are two fans labeled «Grandis XE1236», duplicating the name of the cooler. According to the provided information, these models are modifications of solutions Zephyr 120 PWM, has a higher maximum speed of rotation of the blades (1500 rpm instead of 1300 rpm). New items are based on hydrodynamic bearings to ensure long MTBF (50,000 hours).

SilentiumPC Grandis XE1236 V2

Adjust the rotation speed of the fans is carried out by PWM method in the range from 500 to 1500 rpm, so the two fans are equipped with 4-pin connectors. The noise level in this case is quite comfortable and does not exceed 21 dB.

Fan mount is carried out by using the provided clips. At the image you can notice that due to excessive bending of the proximal clip does not completely enter the recess, wherein it may even fall out. So we had to bend it more for a secure connection of the fan.

In order to connect the new item you need only one 4-pin connector thanks to complete the adapter. The length of the wires from the fan is 30 cm, which would be sufficient to connect even with the most distant sockets.

Installation

Installation of the cooler SilentiumPC Grandis XE1236 V2 is described in the complete instruction, as well as in videos on the official website of the manufacturer. The process is not difficult, but there are some details.

SilentiumPC Grandis XE1236 V2

Let's start with the traditional systems based on AMD processor. Do note that the novelty has a double with label «V1» in the title. They differ among themselves only in the way of attachment: for the installation the first version uses X-shaped device, the SilentiumPC Grandis XE1236 V2 uses more familiar universal plate. Therefore, we will start with the installation process using it.

Initially you need to remove the standard mounting on the motherboard. Next install screws into reinforcement plate, put on anti-vibration pads and install the resulting structure on the system board.

On the reverse side we put four plastic stands. Then fix respective metal fittings with curly nuts using complete wrench. Do note that in the supplied set contains two types of fastenings for the platform AMD, allowing to establish a novelty in many ways: to reveal the heated air to the rear wall or on the top.

After that set the processor, put the thermal interface and install the cooler. As can be seen, the gap between the pressure plate and mounted mounts is too big, so due to short length the complex screws did not allow us to carry out installation.

Then we loosen the nuts that secure the metal brackets to the motherboard. Thus it was possible to neutralize the gap and fix a novelty on the spot.

When using only the internal fan or installing a second fan the cooler radiator will only partially overlaps the first slot for RAM on the left side. Consequently, high radiator modules can be installed in all the slots, except the first. Memory modules with low radiators or without them can be used in all connectors.

The right turntable overlaps second slots so you can try to set a high modulus only in the most distant ones.

Black top plates well harmonize with preset fans. And as the design of our components also differs with predominance of black, the system also has more pleasing appearance due to a combination of dark shades.

SilentiumPC Grandis XE1236 V2

Installation of the cooling system SilentiumPC Grandis XE1236 V2 on the platforms with processors from Intel is almost identical. It uses other reinforcement plate mounting holes which are initially extended to be compatible with all current platforms.

The compatibility is at high level. In case of connecting only the inner fan, the high RAM modules can be installed in all slots. But in the case of the second fan on the right side of cooler, the overclocker memory can be established only in the last slot.

SilentiumPC Grandis XE1236 V2

Complete system looks very harmonious. Do note that for easier building it is better to use extra screwdriver with length of 15 cm.

As for compatibility with the nearby expansion slot and the high radiators around the CPU socket, the novelty has no complaints: connector for expansion cards is not overlapped, and the radiators are at a sufficient distance from the CPU cooler.
