AIO and Oil

[fightingfi]

isnt Mineral Oil i think better for cooling stuff instead of the coolant they use in AIO's?

Thermal conductivity for mineral oil is terrible about 3x less then water. Its only really useful when you need to submerge electronics in it.

There are better coolants but water (mixed with stuff) works pretty well

Plus all the extra drag through viscosity on the pump etc. Some watches are oil filled but over the years they found they had to use thinner and thinner oils as they caused drag on the hands and movement.

Mineral was and still is used to totally submerge an entire system which is/was fully operational see https://www.pugetsystems.com/submerged.php
but I don't recall it being all that wonderful especially after heat transfer occurs.
It was never intended as a loop coolant fulid.

Water + Water Wetter will give you the best cooling.

Mercury works pretty well too

Intriguing idea.... but would totally suck if your system ever sprung as leak or you wanted to change your setup.
