The future of liquid cooling? Wieland impresses with pumpless CPU cooler prototype

This prototype CPU cooler could be a game-changer for fans of quiet PCs

In his latest video, the renowned PC enthusiast/overclocker der8auer has tested an interesting new prototype CPU cooler from a German company called Wieland. This in-development CPU cooler uses a pumpless design that allows it to be much quieter than competing liquid coolers. This custom CPU cooler uses thermosiphon technology, which allows temperature differences to enable coolant flow.

The key aspect of this cooler design from Wieland is that it lacks a pump. This removes a potential point of failure from this new all-in-one (AIO) CPU cooler design. It also removes a source of noise, which is great news for PC builders who want the quietest possible systems.

In his testing, der8auer found that his AIO ran around 8-degrees hotter than a traditional 240mm AIO when using an AMD Ryzen 9 7950X under Cinebench R23. This thermal difference caused AMD’s Ryzen 9 7950X to run at slightly lower clock speeds on the Wieland CPU cooler prototype during the benchmark. This prototype CPU cooler currently supports AMD AM5 and Intel LGA1700 processors.

As der8auer points out in this video, there are many clear ways that Wieland can improve their pumpless CPU cooler prototype. For starters, the radiator section of this AIO can have its fan area better sealed to increase radiator airflow. Additionally, the CPU block could be made of a more conductive material.

Personally, I would love to see a version of this CPU cooling prototype hit the market. This cooling technology has the potential to make closed-loop CPU liquid coolers quieter and more affordable. Let’s just hope that Wieland can improve on their prototype to create something even more impressive.
