AIO Without Pump: Enermax Presents the Future of Liquid Cooling Together with Daikin

At the Enermax stand during Computex 2026, we observed some notably interesting solutions, starting with a pump-free liquid cooling system. At the heart of this new lineup of devices, designed for workstations and data centers, is a special phase change fluid developed by Daikin, the same manufacturer of environmental air conditioners.

The new generation of devices does not yet have a specific name and is characterized by what Enermax calls PFA technology (Pump-Free AIO). The system completely eliminates the mechanical pump and allows fluid circulation to occur through phase change: when heated, the liquid turns into gas and deposits on the radiator walls, which dissipates heat so that it can return to a liquid state and flow within the loop. From the image, it is interesting to note that, given the absence of a pump forcing circulation, the radiator must be installed at a specific angle to facilitate the flow.

The main advantages of this solution are essentially two: an almost absolute quietness of the system and increased longevity, as mechanical and electronic components subject to wear and tear, and thus breakage, are reduced.

As previously mentioned, the system utilizes a liquid developed by Daikin that evaporates at around 49 °C, therefore with a very low boiling point compared to water or traditional liquids. This should ensure faster and more effective heat dissipation. In this regard, we also saw a fully submersible cooling configuration utilizing the aforementioned liquid. However, it seems that the cost of the systems is far from accessible, even for the industrial segment they are aimed at, precisely due to the high cost of the liquid.

ENERMAX also presented the new Mariner WST series, specifically developed for workstation platforms and high-core processors (Intel Xeon and AMD Ryzen Threadripper). The coolers support Intel LGA4677/LGA4710 and AMD sTR5/SP6 sockets, with a structure designed to fully cover the IHS of large professional processors.

The company proposes two different versions. The Mariner WST360-E model integrates a slim 27 mm radiator and is designed for processors exceeding 600W thermal load. The more advanced Mariner WST360-P instead uses a 38 mm radiator and can handle a thermal load of over 730W.

Both variants adopt three 120 mm fans optimized for radiator use. The fans utilize dual-ball bearings, a solution aimed at increasing reliability and operational lifespan even in continuous use scenarios like rendering, simulations, and AI development.

The new line also includes the PF-II 120 fans, characterized by a thick 28 mm aluminum alloy frame, LCP (Liquid Crystal Polymer) blades, and a six-pole three-phase motor. According to ENERMAX, this configuration improves stability, structural resistance, and operational fluidity at high rotation speeds.

Finally, we saw the new Photon power supply series, particularly the 3,200 W model. Lower-rated models will also be available, but all above 1,000 W. The series features ATX 3.1 and PCIe 5.1 supports and an 80+ Platinum certification.

In conclusion, following market trends, Enermax is also focusing its energies on the industrial sector in light of a declining consumer demand. This choice is shared by many hardware manufacturers in view of a true explosion in the AI sector.
