One of the more interesting exhibits at CloudFest in Rust, Germany, were four mineral oil cooled Seamicro based systems being displayed by Asperitas and Boston and described by The Register.  The improved thermal characteristics oils, synthetic or otherwise, offers over air cooling were used to create four very interesting servers.  The CLOUDzone242 houses numerous EPYC 7000 series processors for a total core count of 1,536, 48TB of memory and 960TB of storage while the CLOUDzone241 contains with 96 EPYC CPUs for 3,072 Zen cores, along with 96TB of memory and 768TB of storage. 

Intel fans might prefer the CLOUDzone244 with enough Xeons, to provide 1,056 cores, 48TB of memory and 960TB of storage on board while finally the CLOUDzone243 adds 331,776 CUDA cores across 72 NVIDIA HPC to the specs of the CLOUDzone244.

*Ken not included as it is technically a synthetic oil from condensed gasses.

"Dutch liquid cooling specialist Asperitas and British systems integrator Boston have linked arms on a range of server systems based on "immersion cooling" – with the hardware submerged in giant tubs of mineral oil, a dielectric compound very similar to Vaseline or baby oil."
