A neglected commercial slushie machine becomes an unexpectedly ambitious cooling system once its four freezing cylinders, twin compressors, and beverage plumbing are redirected toward PC hardware. The premise is wonderfully excessive, but there is enough actual engineering involved to keep the project from becoming a simple novelty stunt. Years of accumulated syrup, leaks, inaccessible configuration menus, and the machine’s pressurized design all create genuine obstacles before a computer even enters the equation.
Understanding how the machine works becomes an important part of the build. The explanation of syrup, water, CO2, freezing cylinders, refrigerant jackets, and rotating augers gives useful context for why tapping into the system is harder than simply attaching some tubing. Drilling and tapping the cylinder hardware for standard G1/4 fittings is a clever compromise after the team determines that the double-walled refrigerant construction and pressurized hoppers make other approaches impractical. The restoration also gives the project a satisfying sense of progression, although much of the year-long process is understandably condensed.
The cooling loop itself contains the most interesting experimentation. A custom low-restriction copper GPU block is considered because actual slush needs to pass through the system, only for testing to show that a peristaltic medical pump can push the mixture through conventional commercial blocks. Explaining how the pump squeezes flexible tubing rather than using an impeller makes the unusual component choice easy to understand. Food-safe tubing and new fittings also show some consideration for the fact that the coolant is supposed to remain drinkable, though the broader food-safety implications of circulating a beverage through PC cooling hardware are not explored in much depth.
Crucially, the project does not work cleanly on the first attempt. The mixture freezes solid inside the cooling block, flow nearly stops, the GPU block begins frosting, and CPU temperatures briefly climb alarmingly high as the team tries to generate enough heat to restore circulation. Those failures are more informative than an effortless success would have been, demonstrating the difficulty of balancing a mixture cold enough to remain slushy with one fluid enough to travel through restrictive water blocks. The admission that they lack the refractometer normally used to set the syrup concentration also helps explain why so much adjustment is being done by observation.
Condensation is the largest technical caveat. The team immediately recognizes that the sub-zero coolant can cause frosting and notes that proper insulation would be necessary for prolonged operation, but the experiment proceeds without it. Likewise, the presenter explicitly says the commercial machine was not designed for a continuous computer heat load and does not recommend this arrangement for long-term operation. Those qualifications appropriately limit what the successful demonstration proves: this is an extravagant short-term experiment rather than evidence for a sensible alternative PC cooling architecture.
Eventually getting Black Myth: Wukong running at 4K provides the payoff the entire build has been chasing. With frame generation switched off, the reported performance lands around 75–85 FPS while the displayed CPU and GPU temperatures reach roughly 33°C and 25°C respectively. Those numbers demonstrate that the system can cool the hardware while gaming, but they are not presented as a rigorous thermal benchmark, and the earlier circulation problems make sustained stability an unanswered question. As spectacle, though, playing a demanding game while simultaneously dispensing slushies from the cooling apparatus is exactly the ridiculous conclusion the concept deserves.
Pros
- Converting a commercial frozen-beverage machine into a functioning PC cooling loop is an inventive and unusually elaborate project.
- Explanations of the freezing cylinders, refrigerant construction, augers, syrup system, and peristaltic pump add worthwhile technical substance.
- Failed circulation, frozen blocks, mixture adjustments, and other problems are shown rather than hidden.
- The team clearly acknowledges that condensation and continuous heat loading make the setup unsuitable for casual long-term use.
- Successfully gaming while reporting low component temperatures provides a satisfying practical demonstration of the finished system.
Cons
- The year-long restoration and troubleshooting process is heavily condensed, leaving some potentially interesting technical work unexplored.
- Food safety receives less detailed examination than the unusual beverage-through-PC-hardware arrangement warrants.
- Running sub-zero coolant without insulating the hardware introduces an obvious condensation risk that limits the experiment.
- Temperature and performance results are brief rather than controlled benchmarks, with little evidence about sustained operation.
- The incorrect slush consistency initially freezes inside the cooling blocks and nearly defeats the experiment altogether.
Turning a commercial slushie dispenser into simultaneous beverage service and PC cooling is absurd enough to be entertaining, but the troubleshooting and unconventional engineering give the project considerably more substance than the premise suggests. The final gaming demonstration proves the concept can work temporarily, while frozen coolant, condensation concerns, and limited testing make its impracticality equally clear.
