Be quiet! Silent Base 802 Review

Be quiet! Silent Base 802 wants to usher in a new era in its own product portfolio. As a fundamentally revised ATX case, it now not only offers an extremely high level of flexibility ex-works but is now the next case after the Pure Base DX that fully relies on airflow in the chassis. However, this is not directly pre-installed, but can be converted if necessary – the manufacturer includes the appropriate means. We were excited about the (cooling) performance.

The case series itself can look back on a very long “era”, represented the basic concept or the basic structure be a quiet entry into the case area ( with the Silent Base 800 ). Over the years, optical, functional, and thermal adjustments and improvements ( Silent Base 801 ) to the chassis structure followed. As most of you will have noticed, Airflow has been the benchmark for all assessment bases in the last few months, so it is not surprising that be quiet! has also taken this path, not least with the Pure Base 500 DX. To bring the little history lesson to a close, let’s move on to the latest product.

This now only follows two optical specifications, either completely black or completely white. There are no longer any color accents. You will also continue to rely on insulation elements that are just under 10mm thick. It goes without saying that the housing will also be available in the window and non-window versions. The Silent Base 802 can also be inverted and converted as required. The biggest novelty is more or less hidden in the accessories, because thanks to the supplied replacement front or top cover, the housing can be converted into an Airflow derivative within seconds. The RRP prices for both versions are set at 159 euros for the non-window version and 169 euros for the window version.

But before we go to the detailed view of the latest case offspring, we should take a quick look at the current portfolio, which is available in white. Because with the be quiet! Pure Base 500, the Pure Base 500 DX, and the Silent Base 802 three ATX cases. The three named are chronologically enumerated, last presented chassis of the German company. The Pure Base DX in particular was clearly convincing in the area of ​​the newly created Airflow variant. Let’s see what the Silent Base 802 can do now …

Impressions outside

If you know the Silent Base 801, you will also know the revised version from the outside. Because the Silent Base 802 is not really a fundamentally new development, but rather a healthy evolution of the known and tried and tested. Let’s start with the general one – at the beginning, the different front and cover elements were mentioned, which fortunately are included directly in the scope of delivery. The respective concepts are designed once for a closed and once for an airflow concept. Those components are really easy to change and can either be removed using the sliding mechanism or from the magnetic holder. In any case, this happens within seconds and without tools. The clear design in terms of color is also striking. In the future, the SB802 will be available in black or, as shown, in white without any color applications. This “change” suits the housing.

Let’s come back briefly to the covers in the top area, they are of high quality, reveal very well-balanced gaps, and sit perfectly with attached magnets. The path of sound absorption has also been consistently continued here, at least on the larger of the two elements. The IO panel now also offers other innovations. How to find a full-fledged USB 3.2. Gen 2 connection (10 Gbit / s) with Type-C connector. The two Type-A ports are classified as USB 3.2 Gen. 1 (5 Gbit / s). You are now also up to date in this area. We also find the 3-stage fan control again that acts using a small extra circuit board and the fans are connected there. More on this on the next page (…) The illuminated power button and the jack plug as well as status LEDs complete the picture in this area. Let’s take a look directly at the front. As already mentioned, a second version optimized for Airflow is directly attached to the housing. As with the predecessor, these can be removed, exchanged, or simply removed for the assembly of the hardware. The dust protection grids (front and bottom) are still available in the known design and can also be removed or cleaned very easily.

What one should also mention at this point is that the plastic structures behind the covers have been simplified and the aim was to make it easier for the airflow to access the body. You can see that behind the black mesh cover on the side slits. The proven unlocking of the side panels has remained unchanged. The lock is released by simply pressing a button and the side panels can be folded away and removed. As simple and functional as it can be – very good!

To stay with the side parts – in my opinion, this was implemented very well in terms of feel and value. Certainly, you don’t get polished aluminum, but very solidly manufactured side parts are convincing in terms of quality. In the glass version, one of the two is covered with thick sound insulation; in the non-window version of the housing, it is logically both sidewalls.

The housing stands using both inserted plastic feet (…) Something about the color has to be said again at this point. The white looks very good in its entirety and it will probably be possible to build stylish and interesting systems with it in the future. The word should have got around by now that it is difficult to match the exact color with plastic. Unfortunately, the Silent Base 802 also has to struggle with this “problem”, so that you can see slightly different color differences on various components. Anyone who wants white as a color will (have to) live with this flaw for better or for worse or not even notice it.

Impressions inside

Let’s get to the inside, which basically corresponds exactly to what we already know from the Silent Base 801 and is by no means badly rated. On the contrary, there is more than enough space to install even the largest components. The CPU cooler has a total height of 185mm and the graphics card length should also fit a new GeForce RTX 3090 (313mm) into the SB802, as a maximum of 432mm space is available. Even with the HDD frame installed, it is still 287mm. But it is also gratifying that it can even accommodate E-ATX mainboards.

The entire interior is still very tidy, clearly structured, and offers a lot of space to unfold. The color accents have also been removed here. The rubber grommets are probably still attributed to the original tooling. In this case, the plastic covers are only of a cosmetic nature. If you remove this, HDD frames can be mounted there. Another is included, whoever needs more can reorder the appropriate ones.

The PSU shroud remains flexible. Not only can the top covers be removed individually, but also those on the front. Above all, this has advantages during assembly, so that you can get there better, but of course also in practice. In this way, the airflow is channeled and forwarded as intended. The HDD cage and the mounting space for the power supply unit are hidden underneath. By the way, this can be up to 288mm long – so enough space in this area.

The topic of cable management is unfortunately not as sophisticated with the SB802 as it is with the newer models Pure Base 500 and Pure Base 500 DX, but as already mentioned, this is due to the actual development status of the chassis. There are known and no further developments here. Be quiet! but includes enough Velco-Stripes for the assembly or the cables, so that enough fixings are possible. In general, however, you still have many small slots for laying the cables and are not tied to a “channel”. We have written more about this on the next page. A small distribution board is ultimately responsible for the central fan control if this is what you want. A dedicated SATA power supply and a PWM connection for the mainboard lead from there. In our test, we did without this function and connected the fans directly to the mainboard and, as always, regulated them directly via the speed in the BIOS. More than in the practical part of this article.

The 2.5-inch drives can be screwed onto mounting plates and then attached to the chassis without tools. With 3.5 HDDs, the drive is screwed directly to the bracket and then fixed to the housing frame with knurled screws. If you need more space, you can leave it out entirely, so the entire lower chamber is then free to use – for example, Wakü components. Overall, this area is completely convincing, even if a little dust is already hanging on the mechanisms. Because annoying initial loosening with a screwdriver could not be made out here. Sometimes, subtly, it’s like a VW Golf, you get in and know what to expect.

It is also nice to see that the front openings have been matched to the dust grille. This is to avoid unnecessary air turbulence (noise, less efficiency). A direct comparison also reveals the differences between the two supplied fronts.

The number of fan installation spaces is neat, a total of up to seven pieces (no matter whether 120 or 140mm) can be installed. The same interplay then logically takes place with the radiators or all-in-one solutions. For the assembly of a radiator, there is again the well-known holding frame in the top area, which can also be found in the Dark Base 900 and Dark Base 700, among others. It can be removed so that everything can be prepared externally. There are more details on this on the next page.

The three pre-installed fans are quiet! Pure Wings 2 – 140mm versions that can come up with a maximum speed of 1000 revolutions per minute. We have already presented in a detailed individual test what these fans can do.

Hardware installation

If you look at the assembled result, you will notice the straight lines conveyed by the housing. In the black color, there is even more understatement. You don’t get a tinted window, but all (ugly) slots are covered and a clean look is created. The assembly itself ran without any real problems and was very easy, probably thanks to a large amount of space in the housing.

Unfortunately, the MSI RX 5700 XT is already sagging badly, but this can be seen as a peculiarity of the graphics card. Otherwise, you can’t say much in connection with the housing and the fully assembled system, except that everything could be installed in a very clean, structured, and uncompromising way and there would be plenty of space for additional components.

There is around 30mm of space available on the back, so the cable bundle can sometimes be a bit thicker which you want to fix. Unfortunately, the housing does not yet have a dedicated “control system” which would simplify laying, but this fact is compensated for with enough free space. Overall, the built-in test system was very easy to accommodate. It should also be mentioned in any case that you can easily invert the structure with the supplied means and/or install it on the other side. Hence the removable face of the PSU shroud. Speaking of which, like almost from be quiet! As usual, you can attach the power supply to a dedicated frame and then slide it in from the back.

I already described the assembly in the HDD cage below in the course of the article. All in all, this is also comfortable and does not represent a hurdle. Let’s move on to water cooling compatibility (…)

Water cooling compatibility

As already known from the Dark Base 900 and the Dark Base 700, the 800 series also uses a separate holding frame. With this, you can easily mount your heat exchanger or fan outside the housing and save yourself from annoying fiddling. The whole thing is then pushed into the chassis and fixed with two screws. The fans or radiators are not tied to a fixed placement pattern and can also be moved.

Especially if you want to run an Aio in the top, the new mesh cover is ideal for this and the cooling does not die from the heat. Basically, one can say that the Silent Base 802 supports all common radiator sizes (up to 420mm). With the last one, however, you have to make sure that a 25mm (thickness) is installed here – and that is only possible in the front. As we have shown schematically, accommodating two 360mm heat exchangers at the same time is also no problem. However, it will still take a little brainwash on the circulatory system.

Test system presented

Our case tests are carried out according to a standardized principle. How we test can be read as usual in our case test system. In this way, it is possible to compare all test reports in the area of ​​housings.

Temperature measurement

To show the thermal capabilities of housing, we have documented two load scenarios or rather two ways of looking at them. Basically, the combination of Furmark (@ 1024 x 768px – nonfullscreen) + Prime95 “Custom” (with 8 threads, see screenshot) is used simultaneously, which in turn represents a very good mix of system utilization and practical relevance.

  • Measurement 1: Maximum speed
  • Measurement 2: 800 rpm (the value is set in the mainboard BIOS)

This process will now run for 20 minutes. Once we record the Average value (AVG) over the 20 minutes and in a separate process the Delta T value, i.e. the difference between the measured value and the room temperature. After completing the measurement process, the values ​​are read from AIDA 64. The unit of measurement is logically set to degrees Celsius. Of course, the method used is not immune to measurement tolerances, which means that fluctuations in the range of 0.5 degrees Celsius in the measured temperatures are possible.


Volume measurement

A ” PCE 318 ” sound level meter is used for measurement. This is screwed onto a tripod and records the volume 50cm away from the left side of the housing. The measuring room we use is below 30 decibels base volume and is subjectively assessed, to be described with absolute silence. To have a starting point, the values ​​of the open structure were measured at the beginning, i.e. on a bench table. These will follow later in the first reports and will remain permanently in the overview.

Overall rating

The overall rating is a summary of all temperatures and measured values. In total, this results in a performance indicator about the cooling capacity of each housing. We are currently endeavoring to fill in the basis of comparison so that all values ​​determined are also about one another.

In the local rating, the case is mostly in the middle of the field due to the adjusted fan speed. If you now adjust the revolutions of the fans, in our case to maximum speed, then the thermal impression rotates completely and peak values ​​are achieved. On top of that, it must also be said that the airflow adjustments also tease a few degrees out of the housing. The goals were completely achieved thanks to the new or optional components.

Volume measurement

The volume is measured from a distance of 50cm, aiming at the center of the left side panel. Basically, nothing more needs to be said about the volume measurement, the values ​​speak absolute volumes and cause a bit of positive astonishment. If you turn down the fan and adjust the other components of the system, this is de facto no longer audible. Really good.

The issue of volume is fully taken up by the company name because this is the program here. If you turn the fan down to 800 revolutions, which, as documented below, still brings with it quite good temperatures, you really get an absolutely silent case. Amazingly, I have to say that the sound optimizations are also measurable in a positive sense.


Temperature measurement 800 rpm

Admittedly, at the beginning of the test, I was a bit worried that the temperature values ​​for the individual components would end up in the red limit areas. However, this did not happen under any circumstances, even with reduced fan speed everything stays in the green area and can sometimes achieve top results. A very surprising twist, if you also consider that additional fans could provide a significant increase in cooling performance.

The average values ​​reflect what has been described even more clearly and also show a positive picture when it comes to running the installed PC parts cool and efficiently.

Temperature measurement max. rpm

In terms of temperatures, however, it gets really interesting when the fans work properly. As our overview shows very well, with the Silent Base 802 you get a real airflow monster at your hand, which, apart from the modified CPU cooler, brings massive improvements and top values ​​with it. But it is also noticeable that the CPU values ​​drop so sharply. An additional fan in the top should provide even more improvements, as we did with the be quiet! Pure Base 500 DX.



It is often the case that a facelift is only supposed to be money-making, as it is mostly known from the automotive industry. What you can do with the be quiet! Silent Base 802 is all the more commendable and contradicts this theory, even if the product costs more in the end. But one after the other (…) The manufacturer took up his own existing project and improved it in a really sensible way, even adding a lot of flexibility to the whole. You can say that there really are “games, fun and excitement” in the box – or rather two types of housing in one.

The flexible front and top covers have proven to be extremely useful and easy to use in practical tests. Fortunately, these are not only of a cosmetic nature, no, even measured, there are in places a temperature difference of up to 7 ° C (GPU, CPU), which can be classified as considerable. But not only in this area adjustments have been made, but cosmetic issues have also been “cleaned up” a little. In the future, there will no longer be any color accents in this model series, but really only white or black, if you want it very simple. The case has to accept a bit of criticism in the color matching of some plastic parts, which are not perfectly matched to one another, which unfortunately can happen due to manufacturing. This is not the case with the black version.

All in all, the user gets a really well-made, well-thought-out, and flexible (also invertible again, by the way) housing that has been significantly improved in sensible nuances and these adjustments are also measurable. The only downer from the customer’s point of view is the increased price. For the window version, 169 euros (RRP), and for the non-window version 159 euros (RRP). Experience shows that we can say that the prices on the market will give way a little. But for the extra charge, you get real added value. From our side, there is a full buy recommendation.
