Wieland AIO cooler based on thermosyphon heat exchange

A German company called Wieland has designed a prototype cooler for a CPU. The cooler uses something called a thermosyphon principle to cool the CPU, instead of a pump like a traditional AIO (All-in-One) cooler. The video review from a known overclocker and tech reviewer der8auer compares the performance of the Wieland prototype cooler to a traditional Corsair AIO cooler.
The cooler does not need a pump because it is based on a different heat exchange method compared to traditional AIO coolers. This method is commonly used in heat pumps, water heaters, boilers or solar water heaters. Needless to say, it is a very commonly used method of heat exchange which requires no mechanical pump to move the liquid inside.

Worth adding, that the current version is just a prototype, so design wise it may look entirely different once (and if) it launches on the market. De8auer replaced the fans that were put on the prototype with something he has on the Corsair cooler to maintain the same characteristics for his review. According to der8auer, the cooler currently supports modern Intel and AMD sockets like LGA1700 or AM5.

The Wieland cooler was able to keep the CPU at a similar temperature to the Corsair AIO cooler during gaming loads, but in Cinebench R23 stress test results were more in Corsair’s favor. In this particular test, the Wieland cooler reached a maximum temperature of around 78°C, while the Corsair AO cooler reached a maximum temperature of 70°C. Overall, the thermosyphon design seems to be 8 °C less efficient, which leads to lower Ryzen 9 7950X clocks and lower power use:

The Wieland cooler has the potential to be a suitable alternative to traditional AIO coolers, but there are some areas where it can be improved. For example, the cooler could be made more efficient by closing off the gaps on the sides of the radiator and by using a copper cold plate instead of an aluminum cold plate. Der8uaer also believes that the cooler could be improved visually.
Wieland’s biggest advantage is the lack of mechanical parts, so less change of failure as well as lower noise level, as the there is no pump to generate any noise, the only noise would be generated by the fans. There are some areas where it can be improved before it is ready for the market. For now, it is just a prototype that is not commercially available, but one can be sure Der8auer will keep a close eye on the development of this cooling solution.
