GPUs Practice Reviews Watercooling

Aqua Computer kryographics NEXT review – perfect tailored suit for the GeForce RTX 2080 Ti | igorsLAB

What lasts for a long time must probably just be good. After a long wait, the time has finally come and the Aqua Computer kryographics NEXT 2080 Ti, announced at the end of 2018, completed my test run at the weekend and passed with flying colours. Without wanting to spoil: the patience was really worth it! Even if a few trivialities still signal a need for clarification - the cooler cools as if there is no tomorrow and fits like a one...

What lasts for a long time must probably just be good. After a long wait, the time has finally come and the Aqua Computer kryographics NEXT 2080 Ti, announced at the end of 2018, completed my test run at the weekend and passed with flying colours. Without wanting to spoil: the patience was really worth it! Even if a few trivialities still signal a need for clarification – the cooler cools as if there is no tomorrow and fits like a one. But always beautiful in turn…

In my two articles "GeForce RTX 2080 Ti – Why water cooling is more important than manual overclocking and this does not bring much" and especially "Nvidia GeForce RTX 2080 Ti Founders Edition water-cooled? Forget it, here's the much faster alternative!" I used to go into very detailed detail about the cooling problem and the advantages of a potent water cooling system.

In addition, with the EK Waterblocks EK RTX 2080 Ti RGB, the Phanteks Glacier G2080Ti and the Watercool Heatkiller IV Fullcover, I already had three more coolers in the test, all of which were not failures. Especially the Watercool Heatkiller IV has set the bar for the current test fizzy high and it will be interesting to see how these two copper giants, each weighing 1250 grams, will beat each other in a direct duel.

Since the Otto Normal customer can check the GPU temperatures with selection tools at most, I offer in this article a usual elaborate infrared test with the video of the heat flow and the temperature development, because at the latest with the memory and the There are sometimes extreme differences in voltage converters, which are difficult to determine with normal tests. Testing is always carried out with a maximum power consumption of just under 380 watts for the board of the graphics card and a constant water temperature of 20°C, as well as a room temperature of 22°C and the same Witcher 3 gaming loop in Ultra HD.

All the companies requested have also delivered test samples so far, even if it sometimes took a little longer. Unfortunately, Bitspower has so far, in contrast, and despite direct contact to Asia, completely refused to test. The cooler offered should work equally for all RTX models with reference board, which would have been quite interesting. However, it can at least be assumed that due to such a wide range of supported layouts, the performance may have fallen a bit by the wayside. Perhaps this is also the reason why sampling was not carried out in the end.


Unboxing, scope of delivery and assembly

The completely assembled water block, screws, three 0.5 mm thermal guide pads, as well as two plugs and (far too little) thermal conductive paste are supplied. THE RGB lighting is integrated in the acrylic cover. Unfortunately, RGBpx is a gadget-to-address RGB port that can be connected to Aqua Computer CONTROL units, but not directly to every motherboard with RGB control, which is a great pity.

At least an adapter to the most common 12V ports shouldn't fail. In the accessories you only get the RGBpx cable and a connection to another RGBpx device.  Some Asus motherboards now have such a connection, including various products from Corsair, NZXT or InWin. But a backward-compatible option would be really nice. Perhaps the manufacturer still has an insight? (Update: Upon request, Aqua Computer announced that it would offer a solution in the foreseeable future)

What is missing in the accessories, however, are an H6 hexagonal key for the plugs and sufficient thermal paste. Because a special feature of the kryographics NEXT is the otherwise very pleasing circumstance, that one has placed particular emphasis on the exact dimensions, as well as the fit accuracy. This makes it possible to thermally connect the GPU and the memory directly to the cooling block using thermal paste. From a cooling performance point of view, this is a significant increase in quality, but it is also not always so easy to implement. And who can do it or who often does not trust the end user, because it is not quite so without it (DAU-Alarm).

The one from approx. 1.8 kg of raw material in Germany CNC-milled solid copper cooling block is nickel-plated and, as already mentioned, weighs approx. 1250 grams. the spacers are fit tight enough and are not as easy to turn out as the EK RTX 2080 Ti from EK Water Blocks. The included small Phillips screws are ok, but the head could have been a little bigger.

The manufacturer attaches a mini-tube of a Thermal-Grizzly product with a spatula, which is sufficient for the GPU. What the total of 11 memory modules are to be coated with is somehow in the stars. The supplied paste left a shared impression on me. It is much firmer (viscous) than the usual cryonaut (which also pulls the famous "threads" when pulling away), which suggests either a different composition or a certain aging. Since you don't get far with this paste anyway, you should order a proper portion anyway.

The thin thermal pads logically have a lower thermal resistance than the 1 mm pads, which are unfortunately used so often, but require a very tailor-made production. Any tolerance violation would therefore be punished immediately during assembly. But here, too, the pads have to contend with a certain "breadiness" that I don't really know about the blue pads.

The removal of the two protective foils was the thinner foil for a game of patience with ripping surfaces. The performance should not suffer, but one has to be unusually careful to work. But I suspect, to the rescue of the manufacturer, that my pre-delivered copy was accidentally enclosed with an accessory bag from the farthest corner of the warehouse.

One looks at the board the now more than 10 carried out montages unfortunately a bit, because I have tested various other prototypes in between. If a complete basic cleaning for the optical overkill were to be carried out each time, the protective varnish on the board would already be off. However, if you don't want to be a smudge in private, you can glue the whole edges with the paste with insulating tape or Tesa film or apply the paste to the heat sink straight away.

With reasonably good skills, you've done everything in less than 30 minutes. Also the connection to the terminal and the RGB output of the motherboard are not a witch's work, but with the latter you would have to resort to an Asus model, which my test system unfortunately does not give. That's why the cooler stays dark for the night. But it also has its charm.

Finally, there is now another front and rear view of the screwed-together cooler as a picture gallery:

In the manual I discovered a small error, because the yellow marked areas should actually be green. The rest, however, is accustomed to self-explanatory
