Reader’s test of two GPU water blocks: Alphacoool Eisblock Aurora Acetal GPX-A vs. Aquacomputer Kryographics Next | Community

Alphacool vs. aquacomputer? Today there is a reader review by Elmo from our community that deals with exactly this question of GPU water blocks. Since I find the test, the methodology and the technology used extremely exciting, I once summarized the whole thing as a correct article and, with the consent of the author, changed it slightly so that it fits into the article format. So it’s not an article of mine, but a user review with a lot of potential. In the course of the test, I like to let the author continue to write in the first person, because it’s his test, not mine 🙂

I once cheekily turned the overall view of the complete system to landscape format, otherwise a whole page would have gone on just for the picture:

Original reader test from Elmo from the community

This is my first user review, so I would ask for some indulgence in the wording. The following values ​​were all determined in the same system, with the same settings under the same conditions, in order to compare the two water coolers from Alphacool and Aquacomputer with each other. First of all, I would just like to mention that I don’t have the options like a chiller or a thermal imaging camera, so I can only rely on the temperature sensors in my system and the graphics card. A direct comparison of the test with another system or another test is therefore only possible to a limited extent.

The test system is composed as follows:

Test methodology and implementation

First of all, I bought the Alphacool cooling block in the acetal version, due to the good results in the IgorsLab test, and integrated it into my system. As mentioned in the IgorsLab test, the Alphacool cooling block reduces the flow rate relatively strongly, so that my D5 next can reach a maximum of 95 L / h at 100% performance, which has thus become the comparison value in the tests. In the test, I ran the Timespy several times, because the graphics card exhausted its maximum performance through the test and thus the graphics card could heat up accordingly.

After the test run, the maximum value of the sensors was always read out and noted – the values ​​are given as delta (° K) to the input temperature. The test was carried out accordingly with the aquacomputer kryographics NEXT RX 6800 / RX 6900 nickel-plated version with an active backplate. Various settings were selected in the graphics card driver and with the MorePowerTool; these are specified in front of the data. Both water coolers were installed in the test with Thermal Grizzly Kryonaut to ensure a better comparison of the pure cooling performance of the block.
