Cooling GPUs Hardware Practice Reviews Watercooling

Alphacool Ice Block GPX-N Plexi Light M02 for the RTX 2080 Ti, RTX 2080 and RTX 2070 in 380-Watt Hardness Test | igorsLAB

New revision, new happiness? Let's see what Alphacool made of the ice block GPX, because there is now a new model M02, which is compatible with both the GeForce RTX 2080 Ti, RTX 2080, and the RTX 2070. Today's test has to show how well all this performs and where you can classify the cooler in direct comparison to your competitors.

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 , the Watercool Heatkiller IV Fullcover and the Aqua Computer Kryographcs Next 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 fully assembled water block, a backplate, screws, sufficient 1 mm thermal guide pads for the water block and 3 mm pads for the backplate, two plugs, thermal paste, manual and an inner hexagon tool (H2,5) are supplied. THE RGB lighting is already integrated in the acrylic cover. One relies on an addressable RGB connector and a usable adapter for one of the common 12V connections. Positive.

A 7 mm copper block serves as the starting point, which should be sufficient. 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 supplied hexagon screws are grippy and very stable and at the same time also partially hold the backplate. Here, a look at the manual helps if you want to know which screw is meant for what.

The cooler design is new and universal for the RTX 2080 (Ti) FE. This, of course, entails certain cuts and compromises in order to remain as universal as possible. However, the quality of the workmanship is only a useful mediocrity and one has to be careful against some sharp edge. Even the slight ripple on large, deeper milled surfaces is not really plump now. But it is not so pronounced that the functionality would suffer.

The design is based on the cooling of the memory modules and voltage converters by means of 1 mm pads and only the GPU has direct contact via thermal conductive paste to the heat sink. I find the 1mm pads quite thick and therefore unfortunately also inefficient, which could be revenge later on in the performance. In addition, the coils and flat capacitors are not cooled. For example, EKWB has this error by attaching the matching pads right away.

The manual also gives a puzzle, because you should remove a non-existent protective film from the GPU heatsink. Simpler minds might now try to scratch around because one mistakenly suspects a thin foil (which does not exist at all). On the other hand, it is positive that Alphacool followed my recommendation and moved the pad assembly to the back in the manual.

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 20 minutes. Also the connection to the terminal and the RGB output of the motherboard are not a witchcraft, if necessary just with the 12V adapter.
