Cooling GPus with mineral oil?

[RentGPU]

I was thinking of trying this idea and decrease A/C cooling costs any idea about it? , i would like to hear that you guys used this cooling technique (mineral oil) submerging , maybe you could share advantages and disadvantages

one obvious  disadvantage is replacing the parts if sonthing goes wrong

Well I heard about long time ago, even read some posts in computer magazines, usually this cooling  method are used for some server equipment, but I've never heard miner using it. So if will start using it, you would be the first one.

I have found some youtube videos for miners already used it with thier rigs , but they only talk about how to do it , i know how to do it but i want to know the effect on the long run

Don't you think that this kind of setup requires more space and attention? I have never been into liquid cooling but it seems to be a good idea, especially if it might be cheaper than air conditioning. Your mining equipment should last longer due to lower heat. I'm still not sure whether or not it is worth the hassle (checking oil, being careful not to damage anything etc.).

I have researched into this previously and found there were a few concerns.

If you ever want to RMA or sell the parts that you submerged, you may need to strip the component for cleaning, or leave it to drip dry, a process that could possibly take weeks or months.

Mineral oil may be difficult to obtain in large quantities at a low price in some countries, so a possible alternative was found in cooking oil. This works well, but as cooking oil is organic in nature, it will turn rancid and will need replacement ever so often. However, cooking oil is much cheaper than mineral oil.

Using distilled water is possible for a short period of time until the metal contaminants start to dissolve into the water and render it conductive. This will then cause short circuits to happen.

Due to the law of conservation of energy, the heat from the GPU is not lost. It is only transferred to the mineral oil. You will still need to find a way to cool the oil if you are generating a large amount of heat.

Wratholix did this a few years back with a 6990 rig which is still running till this day afaik with a couple of card replacements.
It's extremely effective but not from a cost perspective unless you've got very solid case building skills. I think he ended up spending around 2.5k RMB on getting a custom heavy perspex case built.
He set up an aquarium pump and a custom built radiator outside for cooling costing another bomb on top of the case etc. However, it was under his desk in his home office running quietly.

i remembered terraminer already using mineral cooling for asic devices. its pretty acceptable for asics but i have no idea for gpu cooling.

I've seen it done before but there is a lot of prep work to do it from my understanding and not very cheap.
Basically scratch it off as voiding all warranties when using it.

[NobodyIsHome]

It can be done but seems like way too much work for anything that needs regular maintenance.

Thx to all , i have access to very cheap parraffin oil (medical) but i don't know if it's good for the job , i think i can try first on an old rig or so for couple of months until summer if all ok i can consider it for all the farm cooling

Immersion cooling with 3M Novec Engineered Fluids is a better option , but probably cost more ...

"What are benefits of Novec over mineral oil?
Many factors should be evaluated when selecting a working fluid. 3M Novec Engineered Fluids have a number of significant advantages versus other classes of dielectric fluids, including mineral oil. In addition to being non-flammable and non-combustible, Novec fluids have the boiling points and thermal stability needed for two-phase immersion cooling operations. Servicing and maintenance are made easy, since the electronics come out of Novec fluid clean and dry."

One of the most important thing in mining is to take heat out of the room and not try to cool it. No mater if you don't have to pay the electric bill.
Install a fan or two and if you don't have windows in that room just install hose for air fans and drive that hot air out.
