ENDORFY Arx 700 Air Test

The former SilentiumPC brand is hidden behind the ENDORFY brand. It was founded in Warsaw, Poland in 2007 and initially focused only on PC components in the field of cases and cooling. However, since the portfolio has since been expanded to include various computer accessories of different categories (mouse, keyboard, headsets, etc.), the manufacturer has made the decision to change the name from SilentiumPC to ENDORFY. However, the main focus in the development of new products remains unchanged: good value, good features and solid workmanship. Today we have the new ENDORFY Arx 700 Air for you to test.

Unlike the Ventum, Signum and Regnum series, the Arx 700 is a completely new development. The Arx 700 is sold in the variants "Air" and "ARGB". The Air has five pre-installed but non-illuminated fans, while ENDORFY gives the ARGB four illuminated ARGB fans instead. Regardless of the version, the manufacturer only installs 140 mm fans, which are supposed to provide a high airflow. In addition, ENDORFY advertises a particularly spacious interior and the resulting high hardware compatibility. Whether the ENDORFY Arx 700 Air can convince us, you can read here.

Typical of ENDORFY, the packaging does without an elaborate design. The cardboard box remains brown and was printed with black and blue paint. Two schematic drawings of the midi tower can be seen, as well as a table with all the technical data and a list of the most important features. Inside the box, ENDORFY wraps the Arx 700 in two conventional styrofoam blocks as well as a plastic film. In addition, a 25 millimeter thick foam mat has been placed in front of the side window. Of course, the obligatory protective film on the tempered glass shouldn't be missing either.

The manufacturer stows the accessories in a plastic bag, which is fastened behind the motherboard tray with a cable tie. It contains all necessary mounting screws and rubber decouplers for hard disk mounting. Furthermore, the scope of delivery includes five 140 mm fans including a PWM control board as well as a mesh dust filter and a short installation guide. What is missing in the accessories, however, are the mounting screws for the power supply. ENDORFY explicitly points out in the manual that these are usually included with the power supply.

In terms of its dimensions, the Arx 700 is Endorfy's largest case to date. With 228 mm (W) x 486 mm (H) x 472 mm (D) and a weight of 8.5 kilograms, it can no longer necessarily be called handy, but it offers a lot of space for hardware as a result. Visually, the manufacturer leaves it at a rather simple design, which puts the main focus on a high airflow.

Thus, the front panel consists of a rather thin plastic frame, in which a large mesh grille has been incorporated, which in turn is attached via a magnet and can be easily removed to the front. This grid is also supposed to serve as a dust filter and has the manufacturer's logo on the lower area. The frame also has additional ventilation grilles on the sides. If you pull the panel off via the recessed grip in the lower area, you can discover the three pre-installed 140mm fans behind it. The rails used for mounting are modular and can be moved inwards, for example to mount a 360mm radiator.

The lid of the Arx 700 Air has a similar look. Thus, this mainly consists of a modular steel plate, in which small, round ventilation openings have also been incorporated, which are also supposed to serve as dust filters. If you loosen the knurled screw on the back, the plate can be removed, revealing three mounting rails for fans or radiators. ENDORFY also provides the Arx 700 Air with a pre-installed 140 mm fan.

The I/O panel was oriented upwards and elongated on the right side of the body. It has three USB ports (1x USB-C 3.2, 2x USB-A 3.0) as well as two jacks for headphones and microphone. There are also two buttons for power and reset. Except for the last end of the HD audio connection, all cables of the I/O panel inside the case are kept black.

The left side panel of the Arx 700 Air is made of a four millimeter Tempered Glass, which is glued to a steel frame and connected to the body by two thumbscrews. The right side panel is made of a 0.75 millimeter thick steel and also has two thumbscrews for attachment. In addition, ENDORFY has equipped both side parts with practical recessed grips at the rear end.

The back shows a typical appearance for a modern midi tower. Thus, the power supply is placed on the bottom and has a modular mounting frame, which is also attached with thumbscrews. Above it, seven reusable PCI slot bezels can be seen, as well as a magnetic cover cap. Finally, in the upper area you can find the fifth pre-installed 140mm fan as well as the nameplate and serial number.

The bottom of the Arx 700 Air is dominated by a large vent for the power supply and mounting points for a hard drive can be seen in the front area. On the bottom we also find the only dust filter of the midi tower. It is made of mesh and has magnets. With their help, the filter mat can be pushed into the corresponding steel holders. Four stable feet made of black plastic, each covered with a layer of foam rubber to protect the surface, ensure a secure stand.

Removing both side panels reveals a very spacious interior. The mainboard tray offers space for mainboards with a width of up to 280 millimeters and even has three additional holes for corresponding spacers. Around the mainboard tray, the manufacturer also equips the Arx 700 with five rubberized openings for cables. In the front and upper area, there is also a large amount of space for fans and radiators, which can transport fresh air into the interior unhindered. Lastly, it should be mentioned that ENDORFY has equipped the motherboard tray in the lower right corner with mounting rails. This is where you could mount a water pump, for example.

If you lower your gaze, you’ll come across an interestingly designed power supply cover. It is partly closed, but at the same time has a mounting place for a 120 mm fan and two large cable openings. Furthermore, the cover is not continuous but leaves room for a radiator up to 65 millimeters deep in the front area. The end piece of the mesh partition tunnel is additionally perforated so that the bottom fan doesn't have to blow against a wall.

Below the PSU cover, things continue in a spacious manner. Since ENDORFY does without a full HDD cage ex works, there is plenty of space for the PSU here first. It has to be pushed into the PSU channel from behind and rests on two elongated strips of foam rubber for decoupling. Optionally, a hard disk can be installed in front of the PSU.

The back of the motherboard tray is convincing with 20 to 35 millimeters of space. This should make it very easy to stow away all cables. Especially the cable channel on the left side and the numerous Velcro cable ties should be particularly helpful. If that's not enough, there are also conventional eyelets for cable ties. Last but not least, the mainboard tray naturally also has the obligatory cutout for installing CPU coolers with backplates.

In the upper left corner ENDORFY has attached the PWM control board for the five pre-installed case fans. Unfortunately, it is not possible to connect additional fans and the board also does not have an additional power connector. Before connecting it to the mainboard, you should check if the fan connector has the necessary specifications.

In terms of storage media, the Arx 700 offers more space than usual. A 3.5″ or 2.5″ HDD can be stored under the power supply cover. The mounting is decoupled via long screws and rubber rings. An identical mounting system is also used for the four 2.5″ SSDs, which can be attached to the back of the motherboard tray or above the PSU cover. Two additional 2.5″ data carriers can be directly connected to the mainboard tray via screws. Of course, there is no decoupling here then.

Looking at the exterior as well as interior workmanship of the ENDORFY Arx 700, there is basically nothing to complain about. The quality of the materials as well as its paintwork appear solid and sharp corners and edges are not to be found. The majority of the materials used also look stable and correspond to the price range. However, the front panel's plastic frame and the right side panel could have been a bit more stable. Overall, the workmanship is okay, but not outstanding. On the other hand, the implementation of many tool-free assembly techniques as well as the function and feel of the modular case elements, such as the lid or front, are praiseworthy. In this context, it can also be mentioned that the side panels can be attached to the body without any problems.

Now we come to the system installation in the ENDORFY Arx 700 Air test. For hardware, we’re using a AMD Ryzen 5 1400 on a ASUS TUF Gaming B550M-Plus with 16GB Crucial Ballistix Sport LT gray DDR4-2666. The Ryzen is cooled by an Alpenföhn Brocken 4 and is overclocked to 3.8 GHz (1.175 V). A GTX 1060 6GB from Gigabyte AORUS is responsible for the image output. The power supply is handled by the fully modular LC-Power LC550 V2.31 Platinum.

As previously suspected, the space available in the Arx 700 Air greatly simplifies the installation of all components. All components were quickly installed and wired. The pre-installed spacers and the stand-off with locking function were also useful for this. Furthermore, all cable management openings were placed sensibly and the reusable cable ties on the back of the motherboard tray are worth their weight in gold. If the used PSU is not modular, then the PSU compartment offers more than enough space to store the superfluous cables there. The complete system looks very appealing and tidy. It also offers enough space for much larger components.

The generous amount of space is also reflected in the hardware compatibility. A considerable 179 and 410 millimeters are available for CPU coolers and graphics cards, respectively. Accordingly, there is currently no component to buy that doesn't fit in the Arx 700. There is also plenty of room for the power supply, which can be between 200 and 340 millimeters long. Radiators can also be easily accommodated in this midi tower. Depending on the depth, a maximum of two 360 mm radiators fit inside at the same time.

Ex works, the ENDORFY Arx 700 Air comes with five pre-installed case fans. These are all of the Stratus 140 PWM type and thus have a frame width of 140 millimeters and a speed range of 240 to 1230 rpm. With their black frame and nine black fan blades, the fans blend easily into the sleek overall look of the midi tower. Each of the fans has a power consumption of 3 watts (12V at max. 0.25A).

Lastly, we come to the temperatures reached in the ENDORFY Arx 700 Air test. During the stress test, Prime95 and FurMark were run for 15 minutes at a room temperature of 20 °C. Furthermore, the test was performed with three different fan speeds.

In terms of cooling performance, the ENDORFY Arx 700 Air definitely knows how to impress. At full speed, the five pre-installed fans make a decent amount of wind and can cool our test system without any problems. In return, fans are clearly audible from the case at a speed of 1230 rpm. However, the background noise mainly consists of fan noise and no high-frequency whirring or whirring. Thus, the fans are less annoying than expected even at full speed.

If you reduce the speed to about 750 rpm, the audible fan noise decreases significantly and the maximum temperatures remain within a green range. The fans are no longer audible at minimum speed, but the CPU temperature in particular then increases very strongly. With an adjusted fan curve, you should still be able to implement a silent system in the ENDORFY Arx 700 Air without any problems.

Now we come to the final conclusion to the test of the ENDORFY Arx 700 Air. In the previous chapters, the midi tower could convince us in many areas. Especially the spacious interior and the five good 140 mm fans were convincing. The latter provide enormous cooling for the hardware and offer enough potential for high-end components. In addition, there are easily removable case elements and the generally very good equipment, consisting of a modern I/O panel, a PWM control board, rubberized cable grommets and reusable cable ties. Finally, the Arx 700 can fit more than usual with a total of seven data carriers.

The Arx 700 doesn't make any particularly big mistakes. Nevertheless, we noticed a few negative aspects. First of all, the thickness of the plastic frame on the front panel and a somewhat too thin side panel are to be criticized. In addition, the manual could definitely be a bit more detailed, or the pictures could simply be larger and have a higher resolution. The missing dust filters for the front and lid are a double-edged sword. Their absence has been proven to improve the airflow, but the interior will get dusty a bit faster. Finally, the lack of power supply screws in the scope of delivery is incomprehensible to us.

With a price of €109 (RRP), the ENDORFY Arx 700 Air is in a very competitive area, where some well-known manufacturers and particularly popular cases are doing their thing. However, the Arx 700 Air does not have to hide from this competition with its overall package. Especially the five pre-installed fans would cost €40 in retail alone. If you can live with the mentioned shortcomings, you will get a very spacious and airy midi tower, which should also be a good basis for high-end components.

With the ENDORFY Arx 700 Air, you get a very spacious and airy midi tower that can convince with a high hardware compatibility and, due to the five pre-installed fans, with a high cooling performance. Minor shortcomings only slightly tarnish the overall result.
