IcetopeTv, I am the system builder and the unit is using Novec 7000, the CPU is bare which means it only has it's intergrated copper top. The CPU is also under 100% load in the videos as well. Outside of that you are right the concenpt is not new it's just that no one has done a system to the level we have, in regards to the consumer market.
They aren't using Novec 7000, I think it's more likely 7100 or 7200 as the CPU temperatures are too high for 7000.
This isn't a new concept, it was done in the Cray II using Fluorinert in the 80's. Novec is the successor to Fluorinert.
Novec is used in a server cooling product called Iceotope, it encapsulates electronics and Novec 7300 inside of a pipe that channels heat into a water jacket.
They are using Novec 7000 and it is boiling near 34C. The CPU temperatures are high because there is no boiling enhancement coating on the CPU lid. There is a BEC on the GPU lid, you should look at those temperatures as representative of what is possible – its remarkable considering these GPUs are built with grease between the chip and the lid. Maybe Eztek would show us some numbers?
BTW – Cray never did passive evaporative immersion. The old Cray machines (Cray 2, T90, etc.) used Fluorinert for immersion cooling but the fluid had a 100C boiling point and never changed phase as it was pumped around. A later machine used evaporative spray cooling which was complex. IBM nearly commercialized a passive 2-phase system called the LEM in the 70s. No one has attempted since but there is certainly renewed interest now that modern packages allow the use of a BEC.
@slannmage - They don't have to waterproof anything, it's a high dielectric fluid and doesn't cause anything to short out. You can just put electronic components right in it with no problem.
This is almost like vapor compression cycle refrigeration. The liquid under low pressure absorbs thermal energy; cooling the components, and as a result, boils into a vapor. The vapor releases the energy it gained when it recondenses; heating the ambient air. Pretty cool to see it working exposed. Temperatures are a little high though, be interesting to see with heatsinks on those chips
It's a special fluid. It boils off the components and there is a radiator at the top to re-condense the vapors. Read the legitreview, or check out vaporphaze's website.
Sorry, IceotopeTV I did not spell your handle correctly.

The liquid Zotac are using in that system is a non-conductive engineering fluid 3M™ Novec™ 7000

If someone is interested, it's boiling point is 34°C.

Could you ask what's that liquid exactly?
Is it top-secret info, which cannot be disclosed?

@slannmage Im guessing they have to water proof the PSU
