The case allows for easy mounting of either SFX or SFX-L power supplies. The PSU is located in the front of the chassis. With the CE declaration a company guarantee, that there product conforms all laws for this type of product. This means the EU had specified a ton of guidelines for every product. Every component is able to cool itself by getting fresh air directly from the outside. Hot air in the case will move to the top and then outside without the need of an extra fan. This principle works perfect and results in an amazing cooling efficiency compare to other cases. The front USB type C port delivers power on my ASUS ROG Strix B550-I with its USB 3.2 Gen 1 connector, but does not transfer data at all. My Oculus Quest 2 stays dead. But I can charge my phone. Great.

If there is one small form factor (SFF) case that has defined the growth in popularity of the SFF movement, it has to be the Dancase A4-SFX. This mini-ITX case has shown it is possible to build highly capable, enthusiast-grade machines that not only are super compact, but also look drop-dead gorgeous. Rightly so, it has been featured as one of our best SFF cases to build with in 2019.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. We believe SFF computers are the future for PC builders – whether you like it or not – and expect to see more and more PC builders turn to the mini-ITX form factor from ATX and look to build smaller, compact systems with equal performance to ATX systems. 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 result is a unique product that is much smaller than all competing cases. This case is perfect for SFF (Small Form Factor) enthusiasts, those who need a highly portable system, developers who require a case with a smaller footprint due to limited desk space, and gamers who want a high-end PC experience in their living room. 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 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.Without trying to patronise, silicon temperature isn't related to how much heat is dumped into your case by the CPU, it's the power draw in Watts. A 15W CPU can run at 95C and a a 230W CPU can run at 60C and yet the hotter 15W chip will result in far, far lower case temperatures because it's only the Watts that are transferred out of the heatsink. If anything, a CPU operating at much higher temperatures is able to extract greater efficiency from the cooler because the larger temperature delta between the air and the heatsink results in a faster energy transfer from hot metal to cool air. In other words, more energy is extracted by the cooler for the same amount of fan RPM and noise.I'm not worried about heat dumped into the case. My point is that with less surface area, you need a more capable cooler with more airflow to keep your silicon temperature low. 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.

In a reversed setup, where the AIO moves to the GPU side next to a conventional SFX form factor power supply. This reduces the length of the graphics card to 173 mm and the height of the AIO including fan to 42mm. Those who can do without two SSDs have room for 92mm AIOs on the ground, such as the 545LC from Asetek. To effectively protect all vents from dust, DEMCiflex provides optional DAN Cases A4-SFX Dust Filters. 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.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)
