Computer Utilizing Hot Coffee as Cooling Fluid
A coffee cooling system was unveiled at Supercon 2023, showcasing a unique and creative experiment in PC cooling. Proposed by Doug MacDowell, this system replaces traditional water in a PC's liquid cooling loop with fresh-brewed coffee [1][2].
The system works by circulating coffee from a coffee maker to the CPU water block and radiators, where it dissipates heat [1][2]. Initially, the coffee is quite hot, reaching temperatures of around 90°C, which could potentially cause the PC to crash [1][2]. However, after about 75 minutes of circulation, both the coffee and CPU temperatures reach an equilibrium near 33°C, indicating that the coffee can cool the CPU moderately well over time [1][2][3].
However, the coffee cooling system has its drawbacks. For one, the coffee itself is not drinkable, as typical PC cooling components are not food safe [1][2]. Furthermore, mold buildup can become a problem with prolonged use [1][2]. The system is more of a novelty or hack, demonstrating the possibility rather than a practical or recommended cooling solution.
It's important to note that this method should not be used for extended periods due to potential mold issues. The coffee is pumped through two radiators on top of the PC, and the system is not designed for regular consumption of the coffee [1][3]. Despite its limitations, the coffee cooling system offers an intriguing exploration in DIY PC cooling, albeit not an efficient or scalable cooling method [1][3].

This unconventional coffee cooling system, demonstrated at Supercon 2023, is a creative experiment in PC cooling that employs technology, as it utilizes data-and-cloud-computing to analyze the system's efficiency over time. Despite its intriguing exploration in DIY PC cooling, the coffee cooling system, comprising gadgets like coffee makers and radiators, is not recommended for extended periods due to potential mold issues, making it more of a novelty or hack, not a practical or scalable cooling method.
