Noctua is a brand known for its air coolers, but it looks like the German cooling manufacturer is finally dipping its toe into alternative cooling solutions. Noctua showed off a prototype of an AIO-esque liquid cooler at Computex, built in collaboration with Calyos, that uses dual-phase thermosiphon cooling to dissipate heat from a CPU.
The prototype has three primary components: a heat spreader, tubes, and a radiator — in this case it is also known as a condenser — all filled with evaporative coolant. Heat from the CPU causes a chemical reaction within the liquid that transforms it into a hot evaporative fluid, causing it to rise to the condenser, which then cools the vapor, turning it back into a liquid. Gravity finishes the cycle by pulling the cooled-off liquid back down to the heat spreader, which is connected to the heat-generating CPU.
