You can do the same with mineral oil, I believe.
However, unlike Fluorinert,
mineral oil isn't a great heat carrier and may actually be less effective
than air in some cases (especially if you don't have a system to rotate it
out to a radiator).
Obviously then, the answer is to provide a hydrogen atmosphere for
cooling (although helium would be nearly as effective). I imagine that
leakproofing would be a real problem.
