DIY - How to Immersion Cool ANY Asic Miner like a Pro! S19, 1246, M30
HTML-код
- Опубликовано: 28 янв 2022
- This is a complete guide on immersion cooling my S19j 90th or Avalon 1246 85th. This system will work for any Asic Miner!
I’ve spent the past few months trying to perfect an immersion cooling system for my Asic miners. There’s limited information out there on the topic so I thought I would share with you my setup and what I’ve learned in the process.
1. I am a DIY’er - not an electrician, plumber, or HVAC professional. When doing any electrical work especially, always follow your local rules and regulations.
2. This video is for guidance and assistance only, I’m simply sharing what I’ve learned in the process and doing my absolute best to provide accurate information.
3. I am not affiliated to or promoting any products in any way shape or form. If your product appeared in the video, thats because its good quality product!
4. This is my first ever video, i have next to zero video editing experience. I welcome any constictive feedback you have in relation to the video or content. mistakes, tips, questions, future video requests, etc
I’ve endured many headaches and failed attempts in this building process…but that’s what learning is all about! This is the successful end result. I believe in using only high quality components and only putting out content that is informed and accurate.
Finally, shout to Anthony Laursen on Reddit, and the Immersion Cooling Reddit community for helping bring this project to life.
Thank you!

This is really well done! Thanks for posting. I am currently working on a 1 s19 miner immersion setup, so your information was super helpful to me! 👍
Hey Jordy, happy to follow you since weeks ;) You've done a nice job, let's become the Jedi of immersive cooling.
Thank you for the video. I have my own hybrid version and was running into some problems. This is a topic that good info is still really hard to find. I been experiencing problems along the lines of enough cooling for my miners. I was experiencing slightly better results then your calculations in one of the comments. This shows that my heat removal expectations were greater then reality. I may have to look into other avenues to pick up my slack. I hate having my miners throttle down or having to shut them off. Good luck with newer versions.
Wow man! You did an amazing job! i'm impressed.
You definitly should shout a step by step video tutorial with a part list.
Thanks! Glad you enjoyed, Sounds good I will explore that idea for future content
Best I ever saw on this topic. I was still not ready after all my research.
Thank you! Feel free to ask any questions you have. More videos to come.
Hey man, great setup! Thank you for your time on posting it and explaining all the way, helps a lot!!! I'm building a similar one myself, but using a fancoil to heat up my home by pulling fresh external air from outside. Regarding your issues with high temperatures: Heat exchange between two non mixing fluids depends on mainly three things: temperature delta (on both fluids), contact area surface and flow rate. Since you are using room temperature air to cool down, it just leaves flow rate as a controlled variable you can work upon without investing on a new cooler. That said, I'm quite sure your cooler is big enough for the application, but you are not moving enough fluid through it for it's maximum heat exchange rate to happen (200L/min for 8,8KW). Your pump says 2700GPH which is 171 L/min, probably less if you count hydraulic losses. Hope this helps!
Thanks! And I appreciate the information, Sounds like you are knowledgeable in this area. I’d love to discuss it more, feel free to reach out to me on Reddit! Thanks!

Awesome video and your build looks nice and clean great job overall! Also Good call on the more expensive pump I have a extremely cost-effective setup. However I would recommend anyone interested in building one to spend a bit more on the pump. My pump had a failure in the main housing then thermal runaway and pump melted. Luckily I am only running a S9i and a E9 Pro. I also opted to go with a Radiator and electric radiator fan instead (Cheap amazon Honda radiator and fan no more than $70) of a oil cooler which works quite well. I also had to put a power control/limiter/switch (cant recall name of item same as one he owns) I noticed that the slower you can pump the fluid through the radiator or oil cooler the better. Since oil isn't able to get rid of the heat it holds the longer you can keep the fluid in the radiator the better. obviously you don't want to have it going too slow. I also opted to keep the Power Supply elevated outside of the tank itself as they contribute to the heat quite a bit.
P.S. regarding a comment i read about PVC... From what I've noticed PVC seems to be fine at least in my case and I've been running for about a year or so with Mineral Oil as i cant afford Bitcool and like i stated my setup is a extremely cost effective version. as cheap as i believe you can make it without jerry rigging something or being afraid of serious issues.
Thank you! And thanks for the feedback on your setup the data is helpful, great to know about the pump. I will eventually build another setup and decrease my flow rate to the exact engineered fluid recommendations, as mine is overkill. Currently my setup is working nicely, so I’m not going to modify it anymore. I will however continue to modify and improve on future builds.
Jordy...you saved me so much hassle. I was looking at the same RISEN manufacturer and it's SO good to know that there cooling capacity charts are not accurate. I was looking at a model rated 5.8 KW cooling capacity for a single s19j I was going to overclock. Figured I'd have lots of headroom even if I hit 4500 watts on the OC. From what you're saying, I'm gonna have to probably beef that up to your model it sounds like. Sucks, but glad to know now and not have all the time and wait just to find it undersized at the end of the build. THANK YOU.
Also, now that i'm in a higher tier price point, I wonder if there are better all in one units to look at....
Awesome! I’m happy to hear it helped you out. Definitely size up. The majority of the cost is in shipping anyways, so play it safe. Fyi, my model is available by one seller on eBay, and the price is inclusive of shipping. However if you plan to overclock you may want to get into a 300L/min model.
I am looking to build a tank and your video is amazing 🤩 Thank you for sharing this..
Appreciate it! Best of luck!
Awesome, thank you for sharing!
Great setup. May I suggest you double each collar where screw is installed on opposites - this helps against potential leaks from the uneven surface under screw. Apply good pressure not high on screws as this can unevenly crimp or even break the collar - those type of collars are not that strong. 👍
Thank you! and you are absolutely right! It’s a great point. I have since doubled them up, as one connection was indeed sweating a little bit of fluid out. I Will add to my highlighted comment and into a follow-up video.
This is super helpful thank you!
this is amazing, thanks for posting this!
Thank you! More to come in the future👍🏼
Beautiful job!
This was great, thanks. I'm looking forward to doing something similar.
Thanks and that’s Awesome! I’ll be releasing an update on the system in a couple of days. Running well, but a Couple tweaks I would make: double up on hose clamps on connections if using poly. Use a 2 part epoxy for adhesive👍🏼
@@BackyardBitcoin Thanks Jordy, looking forward to it, great job on it!
Thanks for posting this. Love the video.
Thank you, I appreciate the feedback!Please ensure you check the updated versions for several build improvements and tips!
Love the set up. How did you calculate what size cooler you need for wattage being used?
Great video, thank you. Did you consider using a heat exchanger? Also it would be interesting to hear your thoughts on mineral oil v bitcool.
Thank you! I am currently using a heat exchanger, I believe there’s just many different names and variations out there. I did a little bit of searching into mineral oil and felt it was just too risky. Apparently component breakdown can occur over time….It was scary enough dipping into fluid engineered for the task!
To hit heat removal specification you also need to hit coolant flow rate. increasing flow rate will help increase cooling capacity from your system
You’re Correct. I’ve worked on that premise. I’ve doubled my flow rate 3 times and increased plumbing to 1” for the most flow I can get. I’m at the point now if I increase my flow rate any further it introduces air bubbles into the system, which decreases the fluid cooling properties. The rad is working super hard, it just cant throw anymore heat away, it’s just not that big of a rad.
I’m at 158L/min currently, in the upper threshold of the companies optimal flow chart
@@BackyardBitcoin i agree. i used a spa pump to move the coolant round my system. it caused major bubbles in the system to the point where i could not see the miner (i have an acrylic case). i had to use a valve to slow down the flow, which got rid of the bubbles
Nice. Thank you !!
This was an awesome video and very insightful as I plan out my GPU immersion loop. Any chance you could make a quick video on your waterfall flow plate design? Also, what was the pump make/model number you opted to use in your loop? Had a tough time making that out in the video. Thanks brotha!
Thanks! I have a link for pictures of current system in description, but yes I will make a video of this and other flow plate designs in the future. The pump is a sicce syncra ADV 10.0. It’s way overkill for what’s required. You could save money and externally mount a smaller pump. You only need 2-4L/min flow rate per kW.
@@BackyardBitcoin you’re the man! Appreciate you getting back so quickly. So with 12 gpu’s pulling around 2,600watts under load I would need around 12L/min pump? Would you say that more total volume of dielectric coolant (I.e greater spacing of equipment in the tank helps with thermals? Or is it better to compact the equipment?) - my main takeaway from your video was that you need to ensure pump and radiator are effective and high quality units. Would be awesome if you’re down to hop on discord to discuss/troubleshoot as I know I’m going to have some hurdles ahead. Thanks brotha!
temperature delta is a significant factor in heat transfer, it probably can remove 77,000 BTU/hr from 300 F hydraulic fluid (not an unusual temp for hardworking hydraulics to achieve), but not your 85 F dielectric coolant. If you moved the rad outside in the canadian winter cold, it would increase the delta-T and thus your BTU transfer rate.
Thank you for this excellent information! I may try this, perhaps closer to spring, as I will need a decent temperature to work in and also make some extensive modifications outside of my house to make it secure and look nice. It’s a tough call to make as currently it provides heat for my home. I need to try and design a system that works well for all seasons.
I can´t understand how people is not mining with a combined setup of sun/wind and ambient temperature cooling in Canada.
Great video. I bought the cooler like yours, but I don't know how to connect the wire to plug it into the socket.
FYI. if youre going to use acrylic. make it no less than 5mm thick. anything less with flex. i also had to reinforce the corners of the acrylic with corners
thank you for the vídeo, Very helpfull.
this pump handles the hot fluid?
and about the plastic of the pump with the coolant in long term?
thank you again for your help.
Yes, so far it’s been great. Another Reddit user has been using this brand and style of pump for approx 7 months with no issues. I can’t speak to the exact material of the casing of the pump, but the ceramic shaft of the pump is compatible with Bitcool.
Any updates on my system, whether negative or positive I will always add to my top comment on the video :)
Thanks for the question!
great project! Congrats. What do you use to simulate avalon fans? (NEVER MIND IT WAS ALL IN THE VIDEO THANKS!)
You will need the ATX 4 pin style spoofers. 4 of them. Check link below ⬇️

Amazing setup here!
What fan would you recommend for 2 S19j pro and how hot does it get? Does this method help with heat within the room or is it about the same with the machine running normally?
I’d recommend the 2431 model 450L/min.
The heat output will be the same, so ventilation in warm climates is a must. I’ll be venting outside in a month or so here as well.
Would you get that cooler again or would you opt for the bigger one? Did you buy on alibaba? You think this one would work for 2 s17s?
Thank you for making this amazing walk through video! I have a few questions about the actual liquid. How many litres/gallons did you use for the who system? Does t evaporate, i.e. do I need to top up that liquid occasionally?
Thanks! It really depends on how big of a tank you are using.I would suggest only using a tank that’s just slightly larger than the size of the miner. My tank has just under 80L total, intended for 2 Asics. If you are running just one miner you can use 40L of fluid with a tank half this size. There’s no benefit to having excess fluid. It does not evaporate, so you you will not need to top It up. Just keep it clean and it will last for years. Hope that helps!
@@BackyardBitcoin Thank you, I really appreciate your response. Looking forward to your future videos😎
What's up bro
I'm talking about Brazil and here we don't have DIY videos for this subject.
I'm impressed.
Three questions: Has the noise decreased much?
Why didn't you submerge the entire asic?
Do I need to do any preparation on the asic before diving into the oil? (in addition to removing the coolers).
Thank you very much!
Brazilian greetings!
Thank you! Greetings🇧🇷
1. Yes immersion cooling is completely silent, the only noise you will have is from your heat exchanger fan.
2. This is one of my earlier builds, I have since modified the hot/cold side divider to be a couple Inches higher to completely submerge both asics. This is actually very important for optimal heat dissipation. If it’s too short, the hot oil can pool up and cause poor flow.
3. You will need to remove the all of the fans and get fan spoofers to trick the asics into thinking the fans are running. You plug them into where the fans plug into.
I do have all of the supplies to build a another complete system if you are interested as well or I can send you the just the parts for a DIY build. I have another heat exchanger, pump, tank, fittings, etc.
Hope this helps out! Let me know if you have any more questions or need any parts for your builld.
Where did you get the pumps and are they compatible with the coolant
Hey, great video. How much liquid was needed to fill the radiator?
The rad itself of this size doesn’t take that much more than the tank allotment. Not sure of the exact amount, but i would factor in an extra few litres to be sure.
I’m trying to build a system that will run 10 miners (mixture of z15’s and L7’s). Can you help me and recommend a hydrolic cooler for this size that I would need?
What's the model number for the upgraded cooler you was going to order ?

Reach out to me on Reddit, and I’ll try to help you out there.
How about the kda asic for example kd6 it has a temp high and low problem
Did anyone try immersion cooling miners with hashing boards without heat sinks?
How bad is the static electricity from running oil over plastic? I'm currently doing something similar and during assembly, the static has been terrible. A bit worried about the miners, but perhaps that's a non-issue. Curious your experience
I haven’t had any issues at all with static electricity 👍🏼 Also if you are doing a custom build just make sure you use a rigid thickness of polycarbonate or acryllic. I should have went a little thicker, there’s a bit of flex in my divider.
I'm looking to recreate this for 2 L7s
I have a few questions:
1. What are the dimensions and thickness of your tank? and is it the same exact one that you linked in your video description, or did you make it yourself?
2. Would this setup accomodate 2 L7 miners?
Hey, so this setup will only support 1 x L7 you would have to find a larger hydraulic oil cooler, or equivalent.
And for the aquarium it’s the exact one linked in the description. I only made the flow plate and divider for it. The thicker the better. Check link below it might help if you aren’t using glass. If you can afford it the plexi materials are a safer choice⬇️

how you calculate the heat of each miner ???
which fan spoofer did you used for the avalon 1246? ive been looking for one much time and i didnt found nothing, do you have a link?
You will need 4 of these total. 1 for each of the 4 fans⬇️

Nice! what's the length of the pump chamber?
The total length is 18”, designed for 2 units. You could reduce in half for 1 unit to cut material and fluid costs.
I have 3 sj19 PRO what size Rad do I need or how did you calculate? I am in the south so the ambient temp is warm year around.
So I’ve been able to determine using this style of hydraulic oil cooler that you need approx 18,000k/cal cooling capacity per 3500watts. I would therefore recommend something of this size or equivalent for your 3 x S19 pro’s. ⬇️
Check out this product on Alibaba App Heat Exchanger Aluminum Plate and Fin Hydraulic Oil Cooler AH3818T 600L/min Hydraulic Oil radiator
Wasnt able to send exact link for some
Reason but this unit has a 50,000 kcal/h cooling capacity, should do the trick👍🏼
Your Eid was great, I wanted to know what water to use in the tank?
Thanks! The liquid is Bitcool 888 dialectric fluid
What kind of plugs are you using? I'm looking for an L630P that has double C13 like that.

And stay tuned I have two videos coming out within the next week on how to wire 220V and how to swap out these cable ends, if you require and help👍🏼
Hello everyone, do you know were I can find a kit ready to run for 6 ASICS: 3 x S19 and 3 x L7 ? I don’t have enough talents to build that .., But I really like it :)
Apologies I didn’t see this sooner. Search DCX immersion systems (Europe) they sell complete systems starting at 8 Asic’s. Alternatively, I know of 2 other smaller companies in North America, find me on the immersion cooling thread on Reddit, and I can direct you to them.
So the heat coming out of the rad is basically the same as how much heat air cooled would create?
Correct, the heat from liquid cooling creates the same amount as air cooling. The Bitcool 888 just does a much better job at absorbing the heat away from the heat sinks than the air does.
What if you just ran 2 of the same machines at once for the oil radiators? Would it be better than 1 larger unit?
It would work, but Would be a lot more plumbing. More connections, more risk of leaks, more maintenance etc. it’s better to use one properly sized rad for them
Хорошая работа!
Есть вопросы:
1. Сколько по времени работает ваша установка?
2. по Avalon 1246: в нем на чипах стоит термопаста или термопрокладки? Не происходит ли вымывания термопасты между радиаторами и чипами?
3. Какая марка блока питания стоит на 1246? Сколько его выходная мощность: общая и на каждую плату?
Are you able to translate this comment to English? I’m unable to read it
@@BackyardBitcoin Good work! I have questions: 1. How long does your installation last? 2. according to Avalon 1246: it has thermal paste or thermal pads on the chips? Is there a washout of thermal paste between the radiators and the chips? 3. What brand of power supply does the 1246 cost? How much power output does it have: total and per board? (Translation)
@@bharathkumar5418
1. the immersion system should be able to outlast the life of the miner given there is no problems with the pump or fan motor on the exchanger. You should never have to change the dielectric fluid if kept clean.
2. Ive only had the Avalon running a few times in immersion for short duration testing, so I’m unsure about the paste washout thus far.
3. Avalon PSU’s run around $650 usd, but come with the unit unless you need a replacement. The Avalon 1246’s run around $8,000 usd new. This model runs at 85 th/s or approximately 28.3 th/s per board in high performance mode and uses approximately 3400watts at the wall when running air.
very interesting and super helpful video for me who’s been thinking of making immersion cooling system, but did you know that Bitcool is not compatible with PVC? they only suggest CPVC or metal tubing.
Glad I could help! And Yes I had a Brain fart at the hardware store and picked up some pvc elbows 🤦🏼♂️. please see the highlighted comment I made under the video I acknowledged the mistake shortly after posting the video:)
Thank you for the Video. Do you use 220L/min radiator? (rate of Flow)
Yes, the 200L/min model works well for 1 high powered asic miner, I just added the link in the description👍🏼
@@BackyardBitcoin thank you very much dear for your answer. I want to try immersiony avalon 3300w using 60L/min, do you think this will work?

hi buddy. Please tell me what pump you are using . Thx alot.
I have just added the pump to the video description
Did you use simulator chips to replace the fan inputs?
Yes I did
You change the avallon firmware? If yes can you please let me know
No, only the S19
how loud is your radiator? 40 db or 60 db? what is about the fans from the PSU? Should i spoof them too?
I don’t have a unit of measurement for decibels at this time, but intend on picking one up soon!
I haven’t tried removing the fans from my PSU’s yet, perhaps a future video when I get it figured out👍🏼
You do not have to spoof fans from psu. In fact, some people dont even remove them. I removed some, unplugged others. Only need to spoof the 4 main fans. I did hear someone mention there is a firmware version you dont need to spoof at all, but I dont know if it is true.
I am currently looking into using bitcool888 where is the flow rate chart and is there a btu chart for antminers?
Engineered fluids recommends 2-4L/Min per kW for flow rate. To calculate BTU’s multiply your total asic wattage by 3.41
@@BackyardBitcoin Awsome thanks that will help to try to locate a cooler
Do you take out the PSU fans? Also, wondering how you get a water tight seal with the heat at 40+C Any redundancy in case of pump failure or leak? Does it shut-down the miner?
Yes you must take out the PSU fans. I’ve always been a little worried about my aquarium seals leaking with the temps, But so far it hasn’t been an issue. I have an Inkbird temp sensor in the coolant with a set high/low range that gives me notifications to my phone if something were to go wrong. Worst case I’m not around, the miners have auto overheat shutdowns built in..but of course you never want it to come to that.
@@BackyardBitcoinIm bouncing around between buying a DCX solution or DIY, your vid was great advice. Thanks
@@ronwatkins5775 thank you. you can make your own significantly cheaper if you are willing to put in the time and are a little bit handy. Roughly 1/3rd of the cost. If I were to do it again I would use a metal tank to ensure there’s no issues. A fabrication shop can weld one easily for you. Feel free to drop me an email jordyandrew@live.ca
I can save you a lot of time and help you avoid mistakes. I also already know the exact tank dimensions you’ll need to make it work. I also have a two spare pumps and another heat exchanger this size I can sell to you for cheap. It’s just taking up space in my garage. Im always willing to help out, reach out anytime.
@@BackyardBitcoinYes, im looking to house approx 8x KS3 miners (3.3kw) total, so about 33KW at 80%. I think I would go with a welded stainless tank. Im not sure I like the idea of pumping the oil through to the dry cooler though, I would prefer a local heat exchanger design to keep the oil side minimized with fewer potential pain points. Ive been investigating DCX and Fog hashing options. I think I would want some redundancy in my pump setup or at least a way to auto-shutdown the rigs if the temps are too high. My setup would have the dry cooler outside through a wall, similar to how mini-split AC's are setup.
@@ronwatkins5775 for sure. Stainless tank all the way. As long as you use yellow gas tape and pipe dope combined you’ll no leaking issues as all, not even a drop. If you do decide to go with something similar to mine or if you need anything let me know I’ll sell you the exchanger for $500. I also have one of the pumps that DCX uses as well and viton seals for use in a 1” threaded steel tank setup. No problem either way, best of luck with the build🤙🏻
Do you still have any extra pumps that you arent using?
I do actually have a couple extra pumps, hit me up on Reddit⬇️
s.reddit.com/c/19fpex1ziraf4?
Bitcool 888 users: **A couple changes I would make after review and feedback - I had a brain fart and used pvc elbows instead of poly elbow fittings when I switched to 1” plumbing. Play it safe and follow the compatibility guide.
UPDATE: *I emailed engineered fluids and received a reply Feb 08, 2022, they advised me the PVC Joints will be ok in the fluid. I wont have to change them.*
UPDATE #2: On Feb 15, 2022 I had one elbow connection start to micro leak. So I simply added a 2nd hose clamp to each connection and that solved the problem. I would highly Recommend doubling up on hose clamps on each connection if you chose to use poly plumbing lines.
UPDATE #3: March 7, 2022: The E6000 did not hold up in the Bitcool 888. it is not on the approved list. So please use a 2 part epoxy for longevity in the system. (See 2 month follow-up) My apologies for those mistakes in the video. See guide below 👇
www.engineeredfluids.com/material-compatibility
Cooling capacity of the AH-1470 model is 8kw (27,000 btu).
Giving some thought to why the Risen cooler isn't doing the job cooling both miners. Could it be that the pump flow rate may be moving the fluid too fast to remove the heat while passing thru the cooler before its returned to the heat source? The Sicca pump rating is 10,000:/hr-2700 GPH (45 GPM) which might be too much flow and is working against you. Just my thoughts.
It’s a great point you raise. In theory, the properties of Bitcool will indeed cool more efficiently by absorbing heat from the PCB’s as it passes through at a slower flow rate. However, I did try two additional pumps in the experimental phase. One with 1/2 and 1/4 power of my current one (thinking bigger was better initially) with little noticeable change to the temperatures. I focused more on reducing the ambient air temp and flow plate design which both had significant impacts on temperatures.
My future builds will a include the engineered fluids specified optimal flow rate.
@@BackyardBitcoin I went back to watch a DCX immersion system video again to compare. Their system is larger but I was curious about the sizing of components, like the pump. They mentioned their pump capacity was 45 GPM (@ 8m of head) so your pump GPM was identical to theirs. I'm wondering if the input/output temp differential would be better putting the dry cooler outside? The DSX system used a heat exchanger so it lowers the amount of Bitcool needed, especially for a long run to a dry cooler. Thanks for your info.
@@wayneo7220 awesome, they have some pretty slick systems. I’m going to have my exchanger outside for my revamped system soon and I’ll make a video on it.
Hopefully soon! It’s Tough with busy short summers here to get these projects completed.
@@BackyardBitcoin One other point I'd like to mention. I was listening to a Compass Mining video and one of the guests mentioned that the thermal conductivity of the dielectric fluid is about 25% that of water and is more viscus, so you have far poorer heat transfer with the fluid and will need to significantly compensate in sizing with a much larger exchanger. I never realized there was such a big difference.
Any tg you involve man? I need immersion group to look up to.

You are getting under performance on the oil cooler because oil coolers require high oil presure and high air flow rate, nice work btw! :)
How could I achieve this? Get a more powerful pump? And should i try to pressurize the cooler more? Maybe by semi closing a ball valve on the outflow? Or should i just try to get a higher flow rate period, and not so much worry on the pressure? Sry kind of trying to be most efficient
nice work!, so mine finally came in and wanted to know how you wired the 220 into the cooler (i understand the transformer bit) is there an extension or something because mine came with a threaded endcap piece?
Thanks! Ok so this type of plug is called a solenoid plug end, that’s the keyword to finding helpful info. Take a regular extension cord and cut off the female end then follow this video. It may not be exact but it’s vey close, and it will get the wheels turning for you. I have also included an imgur link with the wiring diagram for this exact plug. This should help! I’ve been there. Great question!⬇️

@@BackyardBitcoin awesome thank you ill give it a go
Doesn't the oil damage the miner over time
To the best of my knowledge, it’s actually quite the opposite. The miners come out in almost brand new condition. Running cooler and free of dust and debris throughout its life cycle. You may have to add some thermal paste if it’s been reduced, but that’s about it.
Did you have to spoof the PSU fans?
@@BackyardBitcoin Ahhh, ok thanks 👍. I have the main cooling fans removed and replaced with spoofers, just wasn't sure if I had to get more spoofers for the power supply fans.
My apologies! I missed PSU in my first response, I was a half asleep. You do Not need to remove the PSU fans. They can stay in and don’t need to be spoofed.
@@BackyardBitcoin Gotcha, thanks man!
the oil Specific Heat Capacity？it is what fraction of water? i want to use Silicone oil as heat transfer oil。thank you。
Approx 1/4 of water
@@BackyardBitcoin Thanks for your reply。silicone 1/3 of water. i think use silicone will be better in the same situation（AH1470）.
@@BackyardBitcoin I consulted Bitcool specific heat: 2.054 Kj/kg·℃（40℃），Approx 1/2 of water。I hope to help others
Would love to have a full parts list and maybe even a schematic. I am looking at creating this myself!!
Ok, I will soon update the description, or make a follow-up video👍🏼
Very interested in this as well. Would love more info on how the tank was build especially! Great video btw
use one of those cold air hose on the rad
I did actually try that a couple of different times, but directly on the fluid got me better temperatures
the pipe are pvc or special pvc?
@@pierrelacraberie5542 pvc, but that’s short term use only. I’d recommend doing copper or a higher quality pvc to ensure no leaks
Great work but can you take a step back so we can actually see it instead of holding the camera 1 foot away. Would be a lot better for the video aspect of it
Thanks for the feedback. I will make the change for future videos, was my first one
@@BackyardBitcoin Great work though. It's really impressive
@@holyshitcantfindname thank you, I really appreciate that
That pump is not rated to use with bitcool and you cannot use regular pvc. It has to be CPVC schedule 80 or hydronic tubing. Nice setup otherwise
Thanks, and I agree. I do recommend using cpvc or copper in my videos. I’m using poly for short term use as it’s easy to work with. I’m currently building a new and improved setup which will use an external pump with viton seals. My current setup is simply a concept for the community to build on, I appreciate the feedback.
Please have experience with cleaning Avalon 1246 before immersion in oil?
I didn't succeed in the Avalon 1246 oil immersion project and I have a few questions for you.
Can you help me please? Or Can you contact me on email or other communication network. Than you very much
No problem, on Reddit go to “ r/Immersion_Cooling” then look for this video posted. you can find me there to help👍🏼
