Nox infinity sigma review in Spanish (full analysis)

The entry-level chassis market is increasingly competitive. Reflection of this is this Nox Infinity Sigma, in our opinion a direct evolution of Nox Infinity Atom with the implementation of features that go further up its level such as the RGB device with subtle lines that we see in other models of the brand, or the possibility of control the speed of the fans. And of course, quality materials such as a large tempered glass window and capacity for top-of-the-range hardware make this chassis a serious option even for the best gaming equipment.

We have put the glove on this chassis to squeeze it and see what it can offer us in this complete review. Let's start!

We thank Nox for the trust in our team to transfer their product to us for this analysis.

Nox Infinity Sigma technical features

Unboxing and design

What do you do when a package arrives? Well logically open it, Nox Infinity Sigma comes accommodated inside a neutral cardboard box with the black silkscreen and the representation of a sketch of the chassis and its main characteristics.

Inside, the only thing we find is the chassis covered by a translucent plastic bag and two large corks of expanded polystyrene for protection. This will prevent any unwanted contact and bumps during your transfer.

We extract the candy from the packaging to go in search of the screws and elements that we will need to carry out the assembly. All of them are found within the same chassis so it has been necessary to remove the left side plate to access them. Say that as usual, tempered glass is protected on both sides by transparent vinyls perfectly glued on it.

And also as it is tradition in the brand we do not have an instruction book, you always have to scratch where you can. Anyway, we must say that on your website we have detailed information on the characteristics of this semi-tower, so you only have to go to it to be properly informed.

Going into detail, Nox Infinity Sigma is built in 0.6mm SPCC steel, thickness used in all brand chassis due to its good balance between quality and weight. On its side, it installs a 4mm thick tempered glass panel that reveals its entire interior. In all its periphery it is tinted black so as not to expose the metal frame of the chassis. In addition, this panel is attached to the chassis by means of four manual extraction screws and fixed by means of rubber couplings to protect it from both metal contact and vibrations.

The chassis is completely black except its front, which we will see in detail below.

The measurements of Nox Infinity Sigma are quite permissive when it comes to space, we are 465 mm deep, 218 mm wide by 472 mm high, and its weight is 6.2 Kg, making it a semi-tower type. We will obtain good possibilities in terms of the installation of components, since it offers characteristics more typical of large chassis than some of these prices, something that is greatly appreciated for users with few resources.

We now turn to see the front of Nox Infinity Sigma. This is presented in a gray color that appropriately breaks with the dynamics of the typical completely dark chassis. The design is a completely smooth panel with the manufacturer's mark on the bottom and oblique finishes on its sides where the ventilation air flow will enter or exit.

To separate both regions we have a strip with RGB lighting synchronized to the ventilation inside that will be controlled by a button on the I / O panel.

At the bottom, and out of sight, we find a hole to easily remove this front, since it has enough space to install the fans on the outside of this chassis, as we can see in the images. of detail.

We can also see that the ventilation grids do not have a finer particle filter for greater protection, so it will gradually be necessary to manually clean these components.

In our opinion, these gaps are large enough to allow a good air flow for both the inlet and the outlet in case of installing refrigeration. Definitely a plus for this Nox Infinity Sigma.

The I / O panel of this chassis is also found on this front, although if we pay attention, the power button and the RESET button are right at the top in each corner. In this panel we will have the following elements and connections:

2x USB 3.0 Ports 2x USB 2.0 Ports Audio and Microphone Jack input and output Fan speed control RGB Control On / off button (top) RESET button (top)

It is undoubtedly a panel with enough connectivity and a well-distributed design.

We go to the top of this Nox Infinity Sigma to highlight its large ventilation grille that occupies practically the entire useful space. This is protected by a magnetic dust filter for easy removal and cleaning.

The right side panel is made of smooth SPCC sheet steel and is black in color like all the metallic elements of the chassis. This is in charge of protecting the compartment for cable management, which in this case is 28 mm and a fairly remarkable space that surely allows a fairly clean and orderly installation. This panel is fixed at the rear by means of manual thread screws.

We now turn to see the butt of this Nox Infinity Sigma. We will have a compartment for the installation of the power supply located at the bottom of the chassis.

Right above us we have 7 expansion slots provided with metal grilles that are removable with screws and perforated to allow air flow. At the same time we have a side plate for a better fixing of the expansion cards. The plate is also fixed by a manual thread screw.

We move to the top to find a ventilation hole with a pre-installed 120mm RGB Rainbow fan

At the bottom we have a large hole for the introduction of air into the PSU protected by a removable but non-magnetic anti-dust mesh. The floor support is made up of four rectangular rubber feet and large dimensions that allow good air flow under the chassis.

To finish we also see a small ventilation hole in the front, thus expanding the two sides.

Interior and assembly

We now turn to see the interior of this chassis removing both side elements. We will have compatibility for the installation of ATX, Micro ATX and ITX boards. The fairing for the installation of the PSU and mechanical hard drives is completely closed to prevent the flow of hot air from it to the main compartment.

There are plenty of holes for wiring to the board (bottom, right side, and top) and for installing the CPU cooler without removing the board. We consider that they will make the final result a little ugly as they are so visible and do not have rubber plugs.

Based on some images of the assembly, Nox Infinity Sigma allows us to install CPU coolers up to 179 mm and graphics cards up to 370 mm long. No problem, therefore, for the Premium range models.

As far as ventilation is concerned, this chassis will allow us many possibilities due to its size and the distribution of elements. Let's see both the ventilation and liquid cooling section for Nox Infinity Sigma:

Fan configuration:

Front: 120mm x3 / 140mm x2 Rear: 120mm x1 (included) Top: 120mm x2 / 140mm x2

This makes a total of 6 fans of 120 mm and 5 of 140 mm, which is in most cases the maximum allowable. The flow is guaranteed in all three spaces since the front will allow a significant flow of air at the entrance and exit.

Liquid refrigeration:

Front: 240mm / 280mm Rear: 120mm / 140mm

In this sense, the only handicap we have is that at the top we will not be able to install cooling systems with an exchanger and block fans. We do see it possible to install an exchanger without forced ventilation, both 240 and 280 mm.

To finish we must do the storage section and see the capacity of this Nox Infinity Sigma. We will be able to install two 3.2-inch hard drives in the power supply compartment fixed directly to the metal and another two 2.5-inch drives or SSDs on the side of the chassis.

These two would have preferred that they were located in the horizontal area of the fairing of the PSU to take advantage of this part to expand hardware. Also, the result would be very good with better access to SSD drives.

In this back we have a microcontroller to manage the synchronization of the RGB section of the chassis, as well as to allow the different lighting modes and the speed of the fans connected to it. It has a capacity for 8 fans and 4 LED lighting strips, all synchronized.

To finish we leave you with a few photos of the final result with the chassis assembled and in operation. the mount looks clean and very quiet among other things because it only comes with a pre-installed fan.

Final words and conclusion about Nox Infinity Signa

Nox Infinity Sigma is a chassis with very good features for its price, a very elegant and minimalist design along with a good presentation thanks to the RGB section with discreet lighting forms a very successful set. The final finishing touch is its tempered glass window, already practically obligatory in absolutely all gaming chassis on the market.

We highlight its complete front panel with 4 USB ports and the possibility of controlling both fans and lighting directly from it. The cable management is good, since we have enough space, although it could be better if you had elements to route the cables.

The assembly that we have made has high-end hardware such as an AMD Ryzen 2700X, AMD RX Venga 56 graphics card, 16 GB DDR4 and 80Plus Platinum power supply

We also recommend our article on the best chassis of the moment

And it is that we have to put ourselves demanding, due to the strong competition in this sector of the chassis, more and more benefits at a more adjusted price.

In the refrigeration section we miss for example greater protection against dust at the front entrance and it would also be very useful to have another 120 mm fan pre-installed, even if it was basic.

Also not having the possibility of installing liquid cooling on top due to lack of 2 cm is something to consider. Of course, we can install fans in the gap between the front and the interior, something that we value very positively from each to the final finish of the set.

To finish we must talk about the economic section, Nox Infinity Sigma is available in the market for a recommended price of 60 euros, waiting for more stores to publish their price, we believe that it is quite successful, due to the benefits we obtain, although 5 Euros less would clarify the ideas more.
