Submerged mineral oil PC - but EE what would say on it? Finally...

Bud:
Nothing can beat an old good air cooler.

rrinker:
 Funny thing about that one is it looks like there will be a big hole in the air flow right about where the CPU is. Fromt he huge hub of the fan.

Old topic, but since I am with EEVBlog for years I will refresh the subject.

We have tested silicone oils/mineral oils 5 years ago. They do work but they are not good products for long time.

We can provide You best, fully synthetic liquid on the market: https://flameit.io/immersion-cooling/liquid

6 cSt @ 40oC with 0,14 W/mK thermal conductivity and best material compatibility list available.

Not only we have liquid for immersion cooling but also line of own immersion cooling ready pumps. With parts that were not compatible with our liquid replaced at factory

https://flameit.io/immersion-cooling/pumps

We are also designing and manufacturing own tanks for every project that needs tailor-made solutions.

If you have any question do not hesitate asking. I am also on EEVBlog Discord server [felixd#3276]
if You want You can also join our https://discord.flameit.io

Many oil cooled power distribution and transmission transformers 10 kW..1 MW since  over a century have shown a few tips....

1/ Oil used in cooling needs moisture and resistance monitoring.

2/ The post PCB oils are rather costly. Some are hygroscopic and need drying or other treatment.

3/ The transformer is baked out prior to filling with oil to remove all moisture trapped.

4/ Oil is circulated thru coolers by a pump or natural thermal circulation (convection)

5/ The airgap above the oil may have flammable vapors.


My take is that the risk/cost benefits of this scheme should be reevaluated.

The great reduction in die area and power dissipation  on modern GPU and CPU have generally  reduced the need for overclock/water cooling

Finally, beware of fire hazard, leaks and void of warranty of critical parts eg CPU/MoBo, GPU.

SiliconWizard:
Nice necro.

It's rather obvious to anyone sane that doing this is just fine for entertaining purposes and making views on Youtube, but makes absolutely no sense for anyone else.
