3M engineer demonstrates in videos a compact system with CPU submerged in liquid

3M engineer Conny Larsson posted a video on YouTube demonstrating a more compact, sealed design for a CPU being submerged and cooled in 3M Novec dielectric fluids.

A report from HardOCP.com explained, “At least some of the previous demos used 3M Novec 7200 or 7100 fluid, which have boiling points well below 100C. When under a stressful workload, the CPU's IHS boils the volatile liquid, which is re-condensed and cooled by what appears to be a 360mm radiator. Like the previous demo, the entire system is sealed, but it seems that 3M hopes manufacturers will make such cooling systems more accessible in the future.”

 

TechSpot.com added, “The smaller size of the most recent build does make it more suitable for home use, though it’s not exactly what you’d call practical. But it’s still very cool, in both senses of the word, and an impressive feat of engineering.”

 

A full series of videos showing the demo being built can be viewed at https://www.youtube.com/watch?v=tvsIoPkBXnU.
