Computex 2024: Noctua shows an unusual thermosiphon-based LWR prototype
By ForGeeks Noctua unveiled a prototype of a unique liquid cooling system at Computex 2024. Noctua has taken a completely different approach to liquid cooling by eliminating the usual pump.
This is a two-phase thermosiphon that works by heating a liquid, causing it to vaporize and allowing it to circulate due to density differences. The resulting vapor moves through a vapor tube to a condenser where it cools and returns to liquid form. This liquid is then returned to the evaporator, and the whole cycle repeats.
The vapor is then transferred to the condenser, where it is cooled and returned to liquid form.
Noctua collaborated with Calyos, a company specializing in aviation cooling systems, to develop its prototype LLWR. The manufacturer’s main goal was to create a cooler without disadvantages such as pump noise, vibration, or risk of breakage.
The thermosiphon as part of an AWS relies on gravity, so the radiator must be mounted on top of the chassis. With the fans still attached to the radiator. Such an LWR can effectively absorb large amounts of heat before evaporating, making it suitable for cooling power-hungry processors.
Noctua notes that this is a long-term project in the early stages of development. So it’s too early to say when it will be released and how much it will cost.
