Initial thought was to build a high end computer for rendering as well as gaming on the side. But I was never the kind to go for something "normal".

After much googling I came to the idea of oil submerged PCs. Something I could never find was anyone doing this with "modern" parts and so this was kind of an experiment too if mineral oil could handle the heat.

Started out using fish tank materials that I had lying around at home since my beta fish died and gunpla models from my plastic model collection. Oil is SKYDD wood treatment oil bought from IKEA.

After some time though I swapped the water pump for a EKWB model since the water pump was not strong enough to pump oil fast enough through my beast of a radiator. Also removed my gunpla models to make space for my HDD as 1tb was not enough for caching my renders.

Temperature wise, I would say mineral oil cooling is not capable of handling the heat generated by my system. Temperatures will still hit 66.8 Degrees Celsius which is 1.2 degrees short of max temp for my CPU under full load but weirdly does not thermal throttle. After changing to EKWD pump, oil temperature rises to 51.6 degrees max after 4 hours on full load and remains at that temperature.

Note for those who wish to venture into oil cooling, be ready to clean up oil spills until you sort up all the placements and modifications to your build. There will surely be leaks as long as you have wires going into the oil due to oil wicking.
