Wow, I had no idea you could get such a turnkey kit today! I seriously doubt I'll ever have a need for an immersion-cooled machine, but I will definitely dream of the cool setups that could be built in this case.

I really doubt that the fan motors in typical PC components, designed to move air, were made to endure the relatively extreme viscosity of oil.

  At this point you are running thousands of dollars of sensitive electronics outside their design and testing whilst voiding your warrenty. Wearing out a few fans is probably tolerable.

  The authors of the article report that the fans ran just fine in oil, contrary to that same assumption.

  Try it out and see has worked for a lot of people. Not all fans are engineered with no wiggle room, and likely most would fail sooner, but on the other hand, an immersed computer is more likely to run continuously, and startup is harder than continuous running. The oil likelu provides better heat disipation for all parts of the fan as well, which could also prolong life. Otherwise, with better disipation, you can probably remove fans from many components, possibly swapping heatsinks in some cases.

3M has a whole paper [0] on their use of NOVEC for whole datacenter cooling and had a really cool demo [1] of it a decade ago [0] https://multimedia.3m.com/mws/media/1838765O/3m-fluids-for-data-center-immersion-cooling-faq.pdf https://multimedia.3m.com/mws/media/1838765O/3m-fluids-for-d...

  Unfortunately, while the Novec family had ideal properties for immersion cooling applications (and have been fairly widely used in these applications), they are also PFAS. Many of their "advantages" relative to mineral oil fluids come from a handling perspective (e.g. no smell, no obvious residue on immersed items, not flammable), but any handling just means you're unknowingly spreading PFAS around your working area. If you have to treat (appropriately) immersion-cooled systems using Novec as containing persistent environmental contaminants, the handling "advantages" aren't so clear.
