Under oil to keep it cool?

This is pretty crazy, see for yourself! (prototype tank test with hair dryer)

I've seen oil submersion before, but not with a pump and external heat exchanger.   I'm not sure how necessary that is, as the exterior of the tank has a fairly large surface area, and would radiate out a lot of heat anyway.  Something that could be calculated.

[brogramer]

Actually an external heat exchange would be really good cuz then you could have a sealed system and not have to worry about the oil going rancid or getting stuff in it...

Ideally you could vacuum seal it in a container and just have the external radiator.

not so crazy, it is just a simulation before real put in. Today, I have contacted with 3M to check if there is a not so messy method to maintain the desired as noise is the major problem. If the spent can reduce the chance to get diseased, then good.

Dude, you're not supposed to use cooking oil.

I was playing with the idea of an oil tank for blades, but it is completely unnecessary.

I had the resources to create a prototype of it (actually 2), but things move so quick in the BTC world you would regret any additional expense to your mining operation.

Oil submerging is quite good though in terms of cooling, but have some downsides too:

1.) A tank filled with oil and HW is very heavy so not convenient to move if needed. (my prototype weights around 30kgs+ filled up, including pumps and all the other HW)

2.) Maintenance can be quite messy

3.) It's expensive.

4.) If a pump fails the HW can literally fry and get damaged due to no circulation.

Oil is not so expensive as you use cooking oil instead of Mineral one.
If using Intel(R), overheat can be down, can be up after temperature decreases.

P.S
There is a more efficient method which has been using for decades, Fluoride solution by 3M. Started from military Radars to a known supercomputer then trimmed called Novec 7100. I have contacted with 3M, a key person has asked me if I am ready, the desired wattage, I said Ready, Like to cooldown 1300W being for Multi-purpose (Including bitcoin). Although the Novec solution can be more expensive than Oil Cooling, the messy cleaning is completely eliminated, no need to care about the Pump and radiators.

Cooking oil is a very bad idea. It won't last long when exposed to heat not to mention the smell. Mineral oil is the only way to go. The 3M solution is even more expensive than mineral oil.

Mineral oil is better if you can find it at a reasonable price, but its not because its cooking oil that you need to cook it. When pumping it through a radiator it should be easy to keep the oil below ~40C or so, and at those temps and properly sealed vegetable oil should last longer than your asic will be profitable. Even if it goes rancid at some point, it costs next to nothing to replace it. You could probably even "recycle" it by putting it in your diesel car.

[demonmaestro]

you can find Mineral oil at your local drug store. Although the counter clerk may give you an odd look due to i think that stuff is used to "clean you out"...

[jeffhuys]

One of my friends has his pc submerged in oil. Took all the fans out and it works like a charm, never reaching more than 40 degrees centigrade.

[noncecents]

I did a lot of research on this a while back.

You can actually buy mineral oil cooling rigs online.

The problem with cooling with oil is that oil doesn't absorb heat as readily as water or the cooling liquid specifically designed for PC cooling.

Also, it takes a very strong pump to circulate oil through a heat exchanger -- you can't just use a pump designed for water, or if you are able to the pump will have a very short useful life.

Next to cryogenic cooling, oil cooling is probably the most expensive and troublesome type of cooling you can use.

True but nor does it need to. You keep the heatsinks on and you have a very much bigger surface ocntact than your typical waterblock.

Also, it takes a very strong pump to circulate oil through a heat exchanger -- you can't just use a pump designed for water, or if you are able to the pump will have a very short useful life.

OIl is thick, so you will need to buy a much stronger pump than you would think if it were water, but if anything, it may live forever. If you submerge the pump it will be well cooled and perfectly lubricated all the time. You also dont need a high flow rate.

I got very good results with a laing d5. It's not too expensive but very strong (50eur).

Smell can be problem but the property is almost same, perhaps the fat causes that. Additionally , Although the 3M solution is more expensive, no much maintenance needed keeping the same effects.

This depends what you have put in. If motherboard, then it can be quite messy. But not These miners as miners are trimmed being to speed up the harvest. If broken, then you can just replace a new ones.

I don't get the whole oil thing. It's impossible to clean up when you remove it from the oil, so it destroys any resale value to $0. I'd rather not just throw away my money.

I have built a mineral oil submerged desktop before, and I can tell you one thing. Mineral oil is VERY leaky. I kept finding puddles of mineral oil on my desk until I realized that it was wicking up the wires and out of the tank. Also, if you can find a bulk supply at a vet's office then do that. It may sound weirder, but the looks are a lot less weird when you're buying  enough intestinal lubricant for a horse instead of 20-30 1-pint bottles for yourself...

Indeed, I have purchased several bottles at Walmart before to insulate some very high voltage transformers (upwards of 100KV). You can get some odd looks if you ask the pharmacy guy if they have more since they usually only keep like 2-3 bottles on the shelf and he sees you already carrying several bottles
