The AiO kits of watercooling could soon be made obsolete by gas flow cooling technology.
In the world of CPU cooling, there are generally two schools: fans of coolers and fans of watercooling. There are more and more of them thanks to the simplification of technology.
Thus, the so-called AiO kits have made water cooling easier, less risky, but they have not solved the “problem” of the pump, often the main source of noise pollution… especially after a few years.
Liquid flow vs. gas flow
To remedy this, the German company Wieland has imagined a new cooling system which, in appearance at least, looks very similar to these AiO kits dedicated to watercooling.
In appearance only, because the “Thermosyphon” designed by its engineers ultimately takes a very different direction. In fact, Wieland completely does without a pump since it is no longer even a question of circulating liquid in the pipes, but a gas. This gas flow is moved using heat, as in certain boilers or heat pumps.
As we said in the introduction, there is no question of a finalized model yet, Wieland has only presented a prototype. Der8auer, a famous German overclocker, was however able to get his hands on a model.
Optimizations still possible
In order to get an idea of the performance of the technology implemented, Der8auer wanted to compare this prototype to a Corsair watercooling AiO of the same dimensions (240 mm), the H150i.
To make the comparison a little more precise, Der8auer swapped the original fans for Noctua with characteristics close to those of Corsair… and the results are not bad at all. On an AMD Ryzen 9 7950X, the Wieland system holds temperatures equivalent to that of Corsair on video game tests.
On the Cinebench R23 stress test, things turn more clearly in favor of the H150i. While on the Wieland the Ryzen reaches 78°C, it is 8°C cooler with the Corsair AiO. However, the gap is not catastrophic knowing that the Wieland is still only a prototype and that, as Der8auer points out, optimizations can be made.
This includes reducing air leaks from the radiator and swapping the aluminum cold plate for a copper model. Der8auer therefore considers that the technique has potential, especially since the silence objective seems to have been achieved. We will keep an eye on these types of products.
