The one where HashRaptor performs a variety of mineral oil tests on GPU's. We test an unmodified GPU in open air, an unmodified GPU immersed in Mineral Oil, a GPU with no heatsink in mineral oil, a GPU with a heatsink but no thermal paste in mineral oil, and a GPU with a processor foil and heatsink immersed in mineral oil. Let's compare them all and see how they do. And yeah, there is a lot going on in this one. It was tough to edit and we have more to do, so stay tuned for part 4 coming sooner rather than later ;).
Thanks so much for watching Raptors!

💡 Collected Best Practices:
✅ Do not use Rubber in Mineral Oil as it will degrade.
✅ Do not operate the Mineral Oil above 50C as it may damage the tank and other components
✅ Cooler Fins should be aligned Vertically to effectively circulate the oil through the cool.
✅ Fans will spin at a much lower RPM, but will not burn out. They do help circulate the oil.
✅ Check the Tank for any clear plastics that are difficult to detect
✅ Rubber suction cups turned rigid after 1 week in extremely high mineral oil temperatures (with no active cooling radiator).
✅ Use discarded / extra mineral oil for cleaning GPU's
✅ Build your frame first if possible

When you put the GPU in the oil without fans, the fins were horizontal. If you put the fins vertically, it will create natural convection of the oil. Hot oil will rise and cooler oil drawn in.

Nice work there . I have like 48 gtx 1080ti gpus emerged in 250kg of liquid . Some suggestion /to try : 1. Test putting 2 indium foil on the die . I think will improve conductivity and better dissipation . 2. Definitely make that the liquid flow correctly trough the radiator fins of the gpus .(place them vertically). Liquid should circulate from the bottom to the top) 3. Fans or any other plastic/foam should be removed or they will dissolve . 4. Try to attack and plates exchanger water/water . Try to bring the water on half of the exchanger to -0 degree . 5. Thermal pads will dissolve in that oil , need to be removed . 6. To easily clear the gpus (with less mess ), use pure 99.99% isopropyl alcohol , not mineral oil . Waiting for your part 4

I experimented with submerged systems back in the early 2000s. It's definitely a cool project but I always questioned whether it's really viable for production systems. As you said, I don't feel it is viable for most people, considering it makes maintenance such a pain on top of not REAAAAALLY cooling all that well compared to how much effort goes into the system. These days, I'd go after traditional watercooling loop first for a mining rig. Kudos to you for sticking with it! A great watch.

It’s so abstract on first sight but such a great idea actually! Thanks a lot for sharing with the community!!! The thermal paste plus fan looks like the most promising and doable when it comes to prepping the card itself. Maybe some more clever improvements on the build itself in the future (less of the mess with handling in the oil tank as you mentioned yourself) and this might be a really good option.

@boxhead6510 3 жыл бұрын

This has been fun to watch but try mounting the cards vertical so as the oil heats up, it follows along the heat sink. Your external radiator will not cut it once you load up the tank with 4-6 GPU's. Try a car radiator with a fan and shroud (greater surface area and slower fan speed) and pump the oil in the top of the tank (hot) through the radiator and return to the bottom of the tank (cold)

Hola, saludos desde Misiones, Argentina. Si no trabajas en el enfrentamiento del aceite no te va a funcionar. El objetivo principal de usar un medio líquido es para reducir a nada el ruido y mejorar la temperatura de las gráficas para que aumente el MH proba enfriar el aceite por un mecanismo similar a una chopera de cerveza o por un freezer y entonces la temperatura de las tarjetas gráficas se clava en 35° y te aumenta el mh de trabajo. Tenés que sacarle todos los coolers y la pasta , limpiarlas tal como hiciste, pero tenés que tener en cuenta que la salida del aceite caliente está arriba y el ingreso del aceite frío tiene que estar debajo. NO USAR VENTILADORES DE ASIC . NO AL RUIDO. saludos, seguí esperimentando !!

Just a quick update on Part 4 - I get asked a lot :). Part 4 is halfway shot. The custom frame is being built at a fellow miner's workshop. All the parts are there for sizing purposes. We worked on it last weekend, and then the saw blade got damaged and we had to shut down. I should get back over there within days and finish up that frame. As soon as I do, I'll bring it back and complete the last round of testing to finish out part 4. I have a feeling we will still have to tweak and place in the farm in a part 5 to complete the series.

Great series thank you for the production. I believe your problem is the coolant flow paths. The flow of coolant needs to be across the GPU. As a first test turn the boards 90degs so their long length is aligned with the point to point path from radiator outlet hose to inlet hose. It would be interesting to be able to inject a tiny amount of food coloring at the outlet to be able to visualize the flow.

The one in the oil with fans was cooler because the fans are forcing fluid across the heatsink. You *NEED* the fluid to be moved directly through the fins to stop heat build-up. Best bet would be to get pumps to direct a jet of oil directly across each of the fin-stacks

The fans are providing a greater circulation of oil around the video card(s) to those who have them attached. The way that the cards were setup, when all 5 were submerged, was keeping the heated oil in one location. 10-1... GPU3 is that GPU in the middle at the end of your video.

I am loving this series. Curious if the chiller can keep up with 4 GPUs, have you tried increasing the flow rate with a pump? If the one with the fan has the best results it is clearly benefiting from the fan pushing heat away, you might be able to get similar results by simply increasing flow. An option to look at is the Vortec pumps, aquarium shops carry them.

Suggestion!!!! Because of the viscosity of the menial oil heat stay on the same point area. I would suggest you have another tank of mineral oil and secure submersible pump so the you may have circulation of liquid or mineral oil and have movement from and to the other tank. This will serve as you heat exchanger. This process is likely what they use in oil refinary company. You may also use small industrial chiller to cool down the oil As the extra tank to control the temperature at a certain certain point. This process is being use in semiconductor manufacture plant where I work before to cut the IC WAFFER in a high speed cutting machine the brand is DISCO cutting machine.

You got to have a heat sink on it. I haven't finished the video but as soon as I saw you were moving the heat sink I knew it was going to fail. you don't want that heat concentrated. The oil could never keep up. What essentially happens is a vapor barrier is created over the very top of the GPU processor and it will rise really quick and temperature. If you don't want to use a fan and option is to use just a fin heat sink to help pull that heat out and disperse it to allow the oil to do its job

Looks like the wattage is really low? One of the reasons for the temp difference within the tank is the location of the card relative to the flow to/from the pump and rad.

@nilnaelil 2 жыл бұрын

There is an important thing about Indium foil. (which I assume is the foil you are using here) It requires a certain pressure for it to deform properly and plasticly flow into any surface defects of the cooler/gpu. It's around 100 psi I think. With proper mounting pressure it should be far superior to any thermal paste. It's highly unlikely that your gpu mounting comes close to making the proper pressure. There are products on the market with perforated indium foil that requires less pressure. It has perhaps half the thermal conductivity but it is still higher than any thermal paste.

@miked3723 3 жыл бұрын

Did you have the pump and radiator running for the final test? My thoughts are that the the card with the fan and heatsink are coolest because its able to move the warm oil away better. The card next to it was the next coolest and probably benefiting from the oil movement as well. The warmest card was just the furthest away from any oil circulation so it wasnt able to pull away the warmed oil as quickly. If the pump was on then its just not moving the oil around the tank enough so id either use another pump just to circulate the oil in the tank, or keep the fans on the GPUs and it will do the same thing. I see no reason not to use the fans thought, whats the benefit?

@dallasuhlmann5233 2 жыл бұрын

@MartinGonzalez-dk6ff 2 жыл бұрын

At first the temperatures will be low because the oil is at room temperature, when they start to heat the GPUs it will heat the oil little by little, so what you are doing is accumulating the heat in the oil, if you do not cool the oil, a at which point the temperatures will reach 75ºC and the GPUS will turn off. It works fine in the beginning but if the heat is not removed somehow in the end everything will heat up. What you need to do is cool the oil in some way, for which everything will become even more laborious than simply placing an industrial fan in mid-gear that blows over the GPUs arranged in a row and making sure you have an air intake from below and an exit from above in the room or place where you have the RIG.

Have you considered using the permanent thermal pass? It becomes hard and attacks the heatsink very well, it should have no contraindication to be used with mineral oil.

Hey man, I hop you can reply to this... I took a bum 1080 hybrid and removed the water block (no heat sink included) and decided to try a small mineral oil bath to see if I could get this over heating card to run. Sadly the gpu still over heats very quickly and I wonder if the GPU might just be toast. What do you think? I tried using a bubbler and that didn't help. Oil is cool to touch but gpu cooking! It should at least be cool for a bit you'd think? It's in 3 liters of oil with around 2 inches of oil above the pcb.... Maybe the guy sold me a broken gpu? I'm stumped. Figured an oil bath would at least get it working

i tried with 1 x 1070 + psu submerged together. temp 45-48c. then added 2 x 3060. the 3060 temp around 55c (fan glitch trick so the temp is higher). because i added the psu, the oil now flows from gpu to the pump. that seem to help with the temp. and i think if add a seperate cooling reservoir would lower the mineral oil temp further and most likely the gpu along with it. and i really agreed, this immersion project is messy.....

I might be late to the game but. the fans/radiators are pulling heat from the processor so it doesn't overheat / shut down. Have you considered creating a much higher turbulent flow (pump or mineral oil mixer) for the whole tank so the mineral oil will pull the heat away from the processor(s)? This might allow you to eliminate the radiators/fans.

HashRaptor - make your own Indium, its likely going to be better than the crap sold online these days, should be able to find plenty of google examples on how to, this also allows you to get a better thickness in a single sheet rather than layering two sheets so you get the necessary psi for the heat transfer to perform well... beware of using graphite pads (first they perform poorly due to extreme pressure requirements to get any performance) but most have rough edges that can flake off in moving liquids, and thats not something you want floating around electrical devices.

I have a quick question! Is there a lot of heat radiating from the tank into the room? I’m just curious if using submersion keeps the room the rig is in cooler than having a standard rig. Thanks for showing this process!

If anything runs cooler that means more heat is being expelled in to the room. If you put the rad to cool the miniral oil out side the room the room will be cooler. Same goes for watercooling the room will be warmer. Now if your using the tank as a thermal battery and just gaming for like a hour the room temp wont be as hot but the tank will release heat well after your gaming session.

Yep, should heat room same exact amount, will just cool the cards better in theory. Energy not created or destroyed, just exhausting is in a different way. Cool way to do this could be simply putting the rad outside to expel a lot of the heat there

hi there, great video, really want to try it. Can you please suggest, instead of "Food Grade Mineral Oil" any kind of engine/motor/edible oil can be used?

@ethanvalentine4299 3 жыл бұрын

best stuff to use i think was mentioned in part 1 or 2 but its a 3M NOVEC fluid made specifically for this purpose REALLY expensive stuff though definitely not worth buying just for an experiment.... However would be interesting to see a final version using that fluid and see if that makes any major difference in temps. I would not recommend trying this with anything other than Food grade mineral oil or a specifically designed fluid for this purpose as other oils may have additional properties that could make them electrically conductive...

Try turning the gpus so that the oil can circulate off the hot heat sink, stand it up on its tail or head, the way they are situated right now there can't be much thermal movement because the fins restrict the upwards flow of hot oil. Oh and you might want to move the pump to the top of the pool to suck in the heated oil rather than sucking in from the bottom where the cold oil is.
