Famed overclocker Der8auer and Berlin-based online retailer CaseKing showed off a prototype phase change cooler at Computex 2018. The new cooler is a pressurized and closed system that places a block over the processor and uses a vertical tube to connect to a holding tank and a condenser that is cooled by a copper fin stack and two 90mm fans. While phase change cooling is nothing new, what is interesting about this prototype is that the team plans to bring what they call a Phase Shift Cooler to market as a commercial product like an AIO liquid cooler sometime before the end of the year.
The system uses a 3M Novec-like fluid (it is not Novec, however, according to Gamer's Nexus in speaking with CaseKing at Computex) with a low boiling point. The system is pressurized, and the boiling point can be changed by adjusting the pressure of the cooling “loop”. As the processor heats up, the liquid begins boiling off and gas rises up the tube to the condenser where it cools and changes back into a liquid which then flows back into the CPU block with the help of gravity (which does limit placement of the condenser to vertical case orientations above the CPU. The copper fins of the condenser plate are cooled using two fans that do not need to spin at high RPMs.
According to Gamer’s Nexus, Der8auer and CaseKing plan to reduce the size of the cooler and hydralic tubing to make it more in line with a typical 240mm or 360mm AIO liquid cooler and it would be comparable in performance with them without the need for a pump and its associated noise, size, and risk of failure. The Phase Shift Cooler should also be quieter as well, with the planned cooler moving from 90mm to 120mm fans on the final product and the fans not needing to spin up as fast as those high-pressure fans used with water cooling radiators. I have to say that it is an interesting proposition and I am looking forward to more information on this cooler as it progresses!

You may have noticed that extreme overclockers, like those at MSI's Master Overclocking Event in Las Vegas, spend a goodly amount of time trying to insulate their components against condensation that forms when your CPU or GPUs temperature drops well below 0C. NinjaLane has posted an article that shares the basic ideas about protecting your components from frost, though in their case it is a liquid cooling setup with a phase change device in place of a radiator. If -20C isn't cool enough for you they also advise you what changes to make for an LN setup.
"Any time you expose the atmosphere to something cold you run the risk that water in the air will begin to condense. Common forms of condensation would be an icy windshield, water on a cold can of Pepsi, and even the frost in your freezer. The only way to prevent condensation is to insulate against it."
