This time we are going to analyze the NZXT Kraken X63 RGB in its White / white variant, an ideal model for those looking for a polished aesthetic with ARGB and the performance of high-end RL like the Kraken Z series.

This color will be great for most NZXT chassis and plates, setting up a setup with a homogeneous and minimalist aesthetic.

This system is available in 240mm and 360mm variants, but it will be the 280mm that typically offers the most versatility in performance and mounting space for ATX chassis. Behind it we have quality components from Asetek, silent NZXT AER 2 fans and management from the Cam software.

Before we begin, we thank NZXT for their trust in us for giving us this RL system for analysis.

NZXT Kraken X63 RGB white technical characteristics

Unboxing

The NZXT Kraken X63 RGB will arrive in a delivery consisting of a rigid cardboard box of compact dimensions with a case-type opening. An image of the system in its black version is provided on the main face, so we were pleasantly surprised when we opened it and discovered that it is the white version. On the back we have the result once assembled, while on the side will be the specification table.

So we opened the box to find the system divided into components, each one placed on a common rigid cardboard mold. Plastic bags in each element will prevent them from collecting dirt.

The bundle will include the following elements:

In this case, the thermal paste will already be pre-applied on the cold plate, not including any type of syringe or extra compound. The bracket for the Threadripper platform is not included either, since it will already be included with the CPU.

System design and features

Until now we could only find the NZXT Kraken X63 RGB system and its siblings in black, but it finally seems that the brand has decided to take the plunge and also make them in white. It makes all the sense in the world for a manufacturer like NZXT, since a large part of their arsenal is presented in this color, and it will be the best way to combine a chassis with RL and plate and even more elements.

For construction and design purposes, the system will be exactly the same regardless of colour, available in this 280mm format, as well as 240 and 360mm. We already evaluated the performance of the Kraken Z63 version some time ago, although with another CPU, showing that this format will be the most versatile of all as long as our tower supports 280mm fans.

As always, the brand teams up with Asetek to ensure maximum compatibility and quality in critical components such as the water pump. In fact, we have a total of 6 years of warranty, one of the highest in this sector.

280mm white radiator

The usual will be 27mm radiators, but in this case, the NZXT Kraken X63 RGB slightly increases the thickness to 30mm. This increase does not seem to occur in the exchanger itself, but in the reinforcement frame for fan installation. We see how it is somewhat more separated than usual with respect to the radiator, and it is also thicker.

Although it does not mean an increase in the surface area of ​​the fluid tubes, it does imply an improvement in the rigidity and quality of the assembly, since it will better withstand handling and anchoring. The side protections are anchored to the block by means of pins, taking advantage of the side edge to silkscreen the logo and name of the brand, although I know little as it is also white. In the construction, it can be seen that the end chambers are not reinforced with the frame, with a typical Asetek finish in the form of curved corners.

The block is entirely made of aluminium, and as such it has a low weight and good rigidity. The good conductivity and malleability of this metal allows for a dense wavy finning that will unite the 14 longitudinal ducts through which the fluid travels, 7 going and 7 back.

Lastly, the tube connections are made by sockets welded to the radiator and plastic sleeves that hold the tube under pressure. It is a fairly simple shot of little thickness, always in the main color of the system. The tubes used have an external diameter of 11 mm, being made of anti-evaporation rubber and with a length of 400 mm. Although they are a bit thin, they have an outer mesh of thread very similar to Corsair's AIOs, obtaining good length for large chassis and any type of mounting.

RGB Bomb Block

The regular X Series pump block already featured RGB, and this NZXT Kraken X63 RGB will be no exception. Technically they will be the same elements in both series, consisting of a cylindrical design of 80 mm in diameter and 55 mm in total height. This remains painted white like the rest of the system.

The construction of the outer casings will be made of rigid plastic, although internally it has elements in brass and of course copper for the cold plate. The RGB lighting system is implemented in the glass head, which generates an infinite light effect on the outer edge and in turn illuminates the central NZXT logo. To ensure its correct orientation, this head allows 360^o rotation in steps of 30^o. In principle, it can rotate infinitely to both sides as it is independent of light.

We go down to the lower half of the cylinder where we find only the power and USB connections of the system. In the first case, it is a header that includes general power through SATA, a PWM header for connecting the pump to the board, and an NZXT RGB header also for synchronization with the board. On the part of the Micro-USB, it will be the interface in charge of connecting the RL to the operating system to be controlled directly from NZXT CAM. Keep in mind that fan management will be done from the motherboard in this case, and not from the pump controller.

Regarding the technical characteristics of the pump, the manufacturer reports an operating range between 800 and 2800 RPM under PWM control of 12V @0.3A. Quite little information is made available to us, but we do know that it is a 7th generation pump built by Asetek that we also find in more RL systems from Asus or MSI for example, so its quality is beyond doubt.

Concluding with the lower area of ​​this block, we find a polished copper cold plate in a circular format with the thermal paste already applied at the factory. The union is made by means of Torx head screws to the plastic frame where the installation bracket will be fixed. The system will be exactly the same as in other Asetek assemblies, by quick half-turn coupling, easy and admitting any orientation of the head on the plate.

NZXT AER RGB 2 Fans

Now we continue with the study of this NZXT Kraken X63 RGB, stopping at its fans, a white variant of the 2nd generation NZXT AER RGB. These will be self-made, always with the brand's characteristic design of straight and smooth propellers that are quite vertical to ensure a great flow of air.

This time they are characterized by having a translucent plastic outer ring with integrated RGB lighting. Its power will be spectacular, and it provides the ability to manage LED by LED in a fixed mode of effects and colors from the brand's software. The light dispersion will also be better as it is a white system, generating a very striking final result.

Even when turned off, they are aesthetically pleasing units, as their corners are quite original with rubber pads on the screw holes and a black plastic surface around them. The core of rotation is quite small to expand the swept area of ​​the blades, with 4 rear grip points.

Only the 4-pin power cable comes out of them, since in two side corners we will have the input and output header of the lighting. This means that, when installing them, we can link all the fans discreetly with small male-female extensions as we see on the screen, reducing the amount of cables getting in the way.

As for the specifications of these units, we have a range of rotation between 500 and 1500 RPM with 4-pin headers and PWM control. Being slightly less powerful than the non-RGB versions, they will also generate less noise of 33 dBA at maximum speed. They will reach a maximum air flow of 91.19 CFM and a static pressure of 1.52 mmH2O, quite good figures not only for use in radiators, but also in chassis as they are models derived from these.

Mounting system

After seeing each of the components, it's time to assemble the NZXT Kraken X63 RGB on our usual AMD platform.

Remembering the compatibility with the processors we have:

Nothing is mentioned about the LGA 1700 socket that Intel will launch in the next generation, but everything indicates that we will need a somewhat different kit for coupling to the CPU. Without anticipating events, we will have support for the AMD Threadripper platform, although the installation bracket has not been included in the package as it already comes with the CPU.

Asetek's installation system has little to say that we don't already know after a great deal of analysis with this same mounting kit system. For AMD it will be even easier since all motherboards have a backplate, needing only 4 fixing screws and the quick assembly frame on the pump head. In the case of Intel, we will need the backplate that is included.

As for the system connection, we'll use the AIO PUMP header on the board to power the pump, as well as any other header for the fans. These support PWM control, so from the BIOS or from NZXT CAM if we have an NZXT board we can control its RPM. As for the lighting, we will opt for the USB connection as we do not have a brand plate, in which case we would opt for the optional proprietary 4-pin headers.

Management software

We installed NZXT CAM in Windows to be able to manage the NZXT Kraken X63 RGB system both at the RPM level of the pump and its lighting. So that all the elements are detected, we will daisy-chain the RGB header of the pump with the two fans using their side headers.

The good thing about NZXT technology is that it supports LED addressing to individual LEDs, or together by applying effects. It is quite a versatile system, although it does not yet support layers such as Corsair.

Since it is a software that also receives telemetry from the board, we will be able to customize the operation profile of the pump and, ultimately, of the fans if we connect them to a brand controller or board. We will be able to monitor our hardware temperatures, and many other aspects such as Overclocking or noise.

Performance testing

We proceed to carry out the temperature tests with this NZXT Kraken X63 RGB installed on an AMD Ryzen 7 2700X. The test will be carried out with Prime95 in Blend mode for a total of 24 h, monitoring the temperatures with HWiNFO. The ambient temperature of the enclosure will be approximately 23^oC.

< noscript>

As expected, the temperatures are nominal and consistent with a high performance system like this. It supports a 105W TDP CPU with a large margin, so it will do the same with current top-of-the-range CPUs and surely the Intel Core X series and AMD Threadripper are many problems.

Final words and conclusion about the NZXT Kraken X63 RGB

NZXT's AIO RL systems are usually the best in quality and aesthetics, and surely this white version was something that many users were waiting for for your full NZXT setup.

In addition, with the ever-important A-RGB content it will be perfect for gaming rigs and illuminated chassis. It supports synchronization with NZXT boards and management from the CAM software with any board, so we're covered at the customization level. The connection system integrated in the fans reduces the cables and improves the cleanliness of the assembly, which is always a plus.

We recommend reading the best heatsinks on the market

In terms of performance, it leaves no doubt that it is the most versatile size of all, performing almost as well as the 360 ​​versions and even better than some of its rivals. The Asetek components such as the pump and assembly kit make it clear why they are the most used, adding the manufacturer 6 years of guarantee.

The NZXT Kraken X63 RGB will be available for €179.99, which means it's quite expensive, at least more than many of its RGB rivals. This is not new to the brand, and it is true that there are RL systems with a screen and RGB at a similar cost, although it is the price that NZXT puts on its design, quality and performance. Surely we will find it a little cheaper in online stores, it is a matter of searching.
