The next step is to do the test that is described in the norms. You have to do only the test that is necessary. You need special test equipment to do some of the test: For example let fall a standardized iron ball on you case or do a fire test and so on. I think it is impossible to do the test by your own if you aren’t a larger company, but there are accredit companies in every country that can help you to do the test. In Germany for example TÜV Süd, Tüv Rheinland. It will cost between 2000-5000€ that they will do the tests for you. The clever cooling design of the case is similarly spartan in outlook. A separate fan is not needed as the case takes advantage of the integrated cooling of the installed hardware, thus saving valuable space here as well. To ensure that all components are exposed to fresh air the two side panels and the top of the A4-SFX V4.1 have been provided with round air holes over a large surface area along with elongated holes on the bottom to ensure a continuous supply of fresh air. The DAN A4-SFX V3has an extremely compact chassis, measuring a mere 112 x 205 x 327 mm with a volume of just 7.2 litres, that's roughly the size of a shoe box. Through excellent engineering the interior space has been perfectly laid out so that essential hardware only takes up the minimum space required. You should be worried about the heat dumped into the case if you're running a tiny cramped mITX shoebox with restricted case airflow. That heat gets absorbed by every other component in your PC and is directly related to how noisy your case fans will need to be. mITX builds are most often vanity builds that sit right up on the desk next to the user, so noise levels are even more critical than in an ATX desktop where it's further from the user and more of the noise is bouncing around and being absorbed under the desk.

Now you must search form the DIN/EN norms that tell you how to test your product so that it fulfill the guidelines. So for a case that should fulfill 2014/35/EU and 2011/65/EU the norms are: My Dan A4 H2O can still handle high end hardware (not the i9 without an undervolt/power limits :D ), and a big GPU is still going to perform better here than a small one. The sides and top panels are perforated, there's holes everywhere...but there's literally a single RTX 4090 SKU that will fit (the ventus). The FE are a no go because the flow through design could only work with a 4-slots design layout. (There's an offset system for the Two slot FE)On the software side, the test setup includes Windows 10 Pro with Furmark and Prime95 both running at the same time to put the maximum load on both the processor and the graphics card. As I know many of the products that sell by startup over crowdfunding aren’t registered and have real CE declaration with test report, because they think we aren’t located in the EU so what could happen or they don't know these laws. But this could be a problem and destroy your company faster as you can look if a person will be hurt by your product, a bigger company like Silverstone, Lian Li see you as a competitor or a lawyer wan’t to earn money by serve a notice to you. I can only recommand deal with the laws of the countries where you like to export, because every succesfull company do this. Other than that, I agree - configurable TDP is probably the greatest invention in modern CPU technology. You shouldn't be worried about your silicon temperature because that's what the boost algorithm and silicon health agent are for; Unless you have an excess of cooling, they will get the maximum performance out of the available cooling while keeping the roasty-toasty silicon at a safe temperature for its long-term health.

This case is still unique and awesome many years after the first revision. It's a work of art and design. Great quality too. Made me a LL fan as well. Really the best small form factor case money can buy. Whilst expensive the Dan Case proves you do not to spend 300 for a ghost s1 or similar. My case was constructed to a very high standard with no sharp edges, everything aligned perfectly and it was a dream to build in. Worth mentioning the case itself is relatively light which means transporting my final build has been a breeze. Well worth it. The case has been optimised for cooling, with both side panels, as well as the roof of the case have been designed with large air vents. These ensure that all other components are supplied with consistent airflow and that heat is efficiently exhausted. The bottom of the case has been specially designed with elongated air vents to ensure optimal airflow. New for the third revision is the option to mount an AIO panel so that the CPU can be water cooled. To protect all air vents from dust, DEMCiflex provides optional DAN Cases A4-SFX Dust FiltersThe A4-SFX case is a one-man project with the goal of creating the smallest case possible while still using high-end standardized components, such as Core i7 processors and powerful full-length GPUs such as the GeForce GTX 980 Ti.

In spite of the diminutive size of the case, there is sufficient room to install a full size graphics card. The graphics card is installed parallel behind the mini-ITX motherboard in a separate chamber and this means that virtually every single square centimetre of space inside the DAN Cases A4-SFX is intelligently used. A number of creative ideas were needed to create the case. Using a PCIe extender allowed for the most prominent design feature of this case, which is the location of the GPU behind the motherboard. The A4-SFX will come with the highest quality PCIe extender on the market, made by 3M, which allows for PCIe Gen3 and Gen4 support.They folded the rinser cable like so that you cannot fit a 14mm case fan under it. According to the specs the case even holds a 15mm fan. Folding a super expensive rinser cable is no fun. Inside, on the right side, a Mini-ITX format motherboard can be accommodated, on which a CPU with a maximum48 mm high processor cooler can be installed. Flat top-down blower coolers are completely sufficient for cooling due to the ever decreasing TDP of processors. A riser adapter redirects the PCI-Express x16 slot of the motherboard to the left side of the case, where up to 295mm long graphics cards can be installed. The riser adapter is from 3M.

While Real Temp offers excellent and repeatable temperature results, we employ a REED Instruments SD-947 Data Logging Thermometer with four K-Type sensors that have been placed as closely as possible to the benchmarked areas of the CPU, GPU, M.2 SSD, and motherboard chipset. A fifth sensor is used to monitor the room temperature for an accurate delta T result.Daniel put considerable thought into the installation process, which means that unlike most other mini-cases, installing components is straightforward and simple. A Rzyen 7 7800X3D and compact, dual-slot 4070 is about the most I'd want to try and shoehorn into an mITX box. By the time you're adding triple-slot GPUs to an mITX board, there's enough wasted space under the GPU that you didn't need to compromise on mITX in the first place; There's almost enough room for a micro-ATX board - at least in this perpendicular GPU layout. dyonoctisVRM wise Buildzoid was pretty satisfied with the current offering, if you are going high-end you get 10 phases at the minimum, and the mid-range got 8 phases.Buildzoid's VRM analysis of the various mITX boards was indeed reassuring.
