After a Fera HE1224 v2 offering an excellent performance / price ratio (test here) SilentiumPC returns to Conseil Config with the “dual tower” version, the Grandis XE1236! You may not be familiar with SilentiumPC, and that’s okay! Polish company founded in 2007 in Warsaw specializing in silent products (as its name suggests!) While having a quality / performance / price ratio, the products will soon arrive in France, and if the bet is successful they are likely to do very wrong! SilentiumPC offers boxes, power supplies, fans and coolers. The XE1236 is equipped with 2 fans of 12cm, classic so far but it will be offered around 40 €, which may interest more than one, let’s see it all more closely!


The box of the Grandis XE1236 is like that of the Fera HE1224 v2, namely very sober, white with a photo of the product on the front side accompanied by the model and the brand. Once again the marketing has not struck here and there is no point saying that it is the best cooler in the world, it is very appreciable! At the back we find a listing of the strengths of the cooler (“dual tower”, 6 calloducs, “small” size etc.) as well as a QR code leading directly to the manufacturer’s site which offers a detailed video of the assembly and a photo of the bundle, which is really useful information!


On the side we find the technical data of the beast, dimensions, weight, number of fans, sound level, RPM etc.


When you open the box you come across the manual placed on the accessories box.


Inside we find the cooler equipped with a fan in 2 plastic molds and a box containing the second fan.


The bundle consists of:

  • 1 Grandis XE1236 radiator
  • 2 fans 12cm (max 1500RPM)
  • 6 clips for 3 fans
  • 1 adapter 2 x 4-pin -> 1 x 4-pin
  • 1 AMD and Intel compatible backplate
  • AMD and Intel mounting bars
  • 1 tube of thermal paste
  • The necessary screws
  • 1 installation manual

As we can see the bundle is quite sufficient to install the cooler, a tube of thermal paste as well as 6 fasteners to install the 2 fans included plus a third if the heart tells you, we really can not ask for much. more at this price!


Here is the radiator! Composed of 2 turns of 47 aluminum fins (including 1 black at the top) and 6 copper calloducts, the build quality is rather good even if we do not reach the level of a Noctua (but the price is divided here by 2!)


As for the Fera 2 silentiumPC which has attention to detail and look added 2 black aluminum fins engraved with the brand’s logo so as not to leave out people with a case with a window, it’s always nice!


The 6 copper callpipes will offer very good performance, we can see that the base is also made of copper. On the other hand for a nickel-plated finish here, it is necessary to make concessions to keep such a low price.


The base also does not benefit from any particular treatment, a copper plate and that’s it! Some will protest against this but in the end performance should not suffer greatly.


We can see it better here, traces of machining are present and the base does not offer a mirror finish.


The black fan has the SilentiumPC logo in its center, the build quality is once again very correct, we can see on the back that the wires are all black, proof once again that the brand is committed to its design, but this is not finished because the cable is also sheathed!


The fan cable is also sheathed, a little extra that might not be present once again considering the price of the beast.


Here is the beast with the fans installed.

The least we can say is that for a “dual tower” cooler the Grandis XE1236 is rather compact, indeed with only 15.8 cm high it can be installed in the vast majority of boxes on the market, its width of 13 cm will also most certainly not encroach on the first PCIe slot, which is a very good thing! Logically its weight is also very contained for a cooler of this type with 965g on the scale with the 2 fans.

SilentiumPC has however not skimped on the cooling with 6 copper callpipes and 2 fans supplied as standard, with the possibility of putting another fan as an option (with the clips supplied). The fans are 12 cm models rotating at a maximum speed of 1500 RPM for 500 RPM at least for a maximum consumption of 1.44 Watt and a sound level ranging from 8.9 to 21 dB which should ensure a very appreciable silence while being able to ventilate well if the need arises.

The main strong point of the Grandis XE1236, however, is undoubtedly its price of around 40 € which is about half the price of high-end “dual towers” such as the NH-D15 at Noctua and Dark Rock Pro 3 at be quiet !, let’s see what’s in his stomach!

Videos are available on the manufacturer’s website to help buyers, that doesn’t mean I won’t detail the steps, but here they are anyway!

To start we will tackle the back plate of the motherboard, it is worth taking the 4 square head screws as well as the plastic clips below:


Then you have to put the screws in the holes corresponding to the socket of the motherboard, 1156 in my case therefore the middle hole and slide the plastic clips over the metal tab, like this:


Once the 4 screws are installed in the 4 corners, just place everything under the motherboard and we end up with this:


Then you have to put the 4 black plastic spacers on the screws, like this:


The 2 fixing bars are placed on the spacers, 2 orientations are possible either with the fan which blows towards the top of the case or towards the rear.


Once installed, all you have to do is screw them:


Do not forget to put a grain of thermal paste rice on the processor, especially do not put too much!


Finally, you have to put the radiator (without the fans) on the processor and screw it, nothing could be simpler! All you have to do is fix the supplied fans, plug them into the 2 x 4-pin -> 1 x 4-pin adapter and plug it into the PWM connector of the processor!


And There you go! The SilentiumPC Grandis XE1236 is now ready to do battle!

Memory / PCIe compatibility

The dual radiator coolers are often problematic for the choice of memory and the blocking of the first PCIe port, let’s see what this gives:


As we can see the Grandis XE1236 goes far beyond the memory slots, it will be necessary to pay attention to the type of memories installed, even if the fan can be shifted upwards to leave a little margin.


The first PCIe port on the other hand is quite usable, and it’s really a very good point for this type of cooler!

The test platform

The SilentiumPC Grandis XE1236 has been tested on the configuration below:

  • Processor : Intel Core i7 875K @ 3.2 Ghz
  • Motherboard : Asus P7P55D
  • Mémoire: Kingston HyperX 4 x 2 Go 1600Mhz
  • Disque dur: WD Raptor 150 Go
  • Graphics card : Sapphire Toxic 5850
  • Power supply : Seasonic X650

The test protocol

The core i7 875K has been slightly overclocked to 3.2Ghz. The temperatures under load are an average of all the cores for 3 tests of 30 minutes on OCCT, the temperatures at rest were taken after 15mins on the desk (still an average of the 4 cores).

The cooler has been tested against:

  • be quiet! Pure Rock (tested here)
  • be quiet! Dark Rock 3 (tested here)
  • be quiet! Dark Rock Pro 3 (tested here)
  • Noctua NH-U12S (tested here)
  • Noctua NH-U14S (tested here)
  • Noctua NH-D15 (tested here)
  • Scythe Mugen 4 PCGH (tested here)
  • SilentiumPC Hera 2 HE1224 v2 (test ici)

The temperatures


The double radiator cooler from SilentiumPC is really a very good surprise, the temperatures are really excellent! In 5V it manages to keep the processor at 61 °, in PWM 53 ° and once fully down we even go down to 51 °! It clearly does not stand out against the other coolers in the comparison by being a few degrees from the twice more expensive coolers such as the NH-D15 and Dark Rock Pro 3, it goes without saying that the performance / price ratio is clearly at the bottom. advantage of the Grandis XE1236 from SilentiumPC. Let’s see what this gives in terms of noise pollution.

Noise pollution

Warning: Part to be taken with a grain of salt, unfortunately not having access to the appropriate equipment and using an android application to take the readings The measurements below are only indicative! The readings were taken 15cm from the cooler.


Nerf of war and main objective of SilentiumPC the noise pollution is really very good, in 5V it is inaudible except really a very slight engine noise when you stick your ear to the fan. In 12V it is heard but there is no parasitic noise, only the noise of the air flow is present which is not very annoying, especially when the cooler is in a box. The best understood remains as usual the PWM mode which, in my test configuration only reached 38dB at full load, there is no need to say SilentiumPC worked really very well at this level, especially once again by seeing the price of the product.


Here we are at the end of this test, what about the SilentiumPC Grandis XE1236?
SilentiumPC makes it a point of honor to offer products with an excellent performance / price / noise ratio and it is clear that the Grandis XE1236 fulfills the contract perfectly. The build quality is good, and even though SilentiumPC goes all the way to keep costs down they don’t give up the look with black aluminum plates on top, sheathed cables and even an adapter for sheathed fans, little details. who could very well have been excused if they had not been present given the sale price.

The performance is very good, placing the XE1236 a few degrees from the biggest coolers on the market, it will have no difficulty in cooling the processors, even overclocked. Regarding noise pollution and as the name of the brand indicates, the cooler is really very discreet, in 5V and in PWM mode at rest it will simply be inaudible to be very discreet in load (in PWM) but unfortunately enough noisy in 12V.

Offered at a price of around 40 € the Grandis XE1236 will really be an excellent choice for anyone looking for a cooler going straight to the point and having one of the best performance / price / silence on the market, perhaps the next cooler in your config. gamer?


  • Price!
  • Quiet
  • Look for an entry-level product
  • Performances
  • Does not block the first PCIe port.


  • .. but “low profile” memory require

A big thank you to Marcin from SilentiumPC who allowed me to do this test.
