Bitfury is starting 40MW immersion cooled farm.

This 3M and Allied Control solution needs closed cabinet and also a condenser.

Are there home miners using immersion cooling?

Ofcourse there is https://www.youtube.com/watch?v=gcb9TyQP5ZA    ;D

It's highly  unpractical to use for mining at home. A small demo tank can be easily made.
You can find a lot of YouTube videos about it.
But avoiding leakage is not an easy task, and the Novec is really expensive, like 70$ per liter (sold by the weight).

^Mineral oil is much cheaper, but of course it is messy, and after mineral oil bath, your miner's resale value is 0  ;D

From what I read, that Novec can actually be used to wash hardware so it would not be problem, but with that, one would need airsealed tank and condenser loop.

Mineral oil bath can apparantely run with passive cooling, though I don't know, if passive cooling is enough for mining hardware.

Mineral oil cooling is a single phase cooling method. The oil has to be pumped and in the case of dense hardware quite rigorously. 21 Inc used mineral oil already in 2014.

What makes the Novec/3M boiling approach so efficient is the phase change from fluid to vapor and then back to fluid. The fluid circulates passively (without spending energy on this circulation).
