Antminer S9+ Immersion Cooling on a Budget

- Learn from my mistakes of trying to do cheap immersion cooling of an Antminer S9+. It cost me an extra $200 to learn the hard way what does and doesn't work. I spent the money getting it wrong to help you get it right the first time.

Here are the links to the products that I talk about in the video (I received no promotional compensation for these products. This is just what I used, and where I got it.)

UPDATE: The fuel pump failed in short order and has been moved to the NOT work list. However, the new pump I purchased is AMAZING and highly recommended. I included the link below.

Oh my gosh this video was so entertaining and informative at the same time. Your presentation style is so comedic. Fantastic work and cheers to your perseverance and learning ability with this ambitious project.
Solid video, I'm copying the design by space design warehouse
Great Video, thanks for making it. Im starting my build and am using some of the same components. One quick question, How did you power the Fuel pump???
I used a "run of the mill" AC adapter that I had lying around. I suspect, however, that the internals on that pump were plastic and it quit pumping after a few weeks. I've added an updated, cast iron, pump to the recommended list and it runs on AC so you can just plug it in.
I can see in your last result that autotuning was still on. What's your hashrate now that it's stable?
Did you even bother to read the 85 page primer from Engineered Fluids, or their material compatibility list, or even their extensive FAQ? When in doubt DON'T CHEAP OUT!!
I found that Engineered Fluids' hardware is prohibitively expensive when you attempt to use a single miner. The savings come from scaling up AND running your miners in excess of 110%...not being satisfied with sub 100%. However, to be fair to Engineered Fluids, they provide all of the information to build your own equipment.
Some issues to consider is material incompatibility, for one. That black stuff is probably the rubber hose that is dissolving over time. The flow rate of a pump is highly dependent upon the tubing and elevation of your pump, along with the type of pump chosen. For example, when you added the second radiator, you dramatically added more friction to the system that your tiny fuel pump wasn't designed to handle. Also, a car's fuel pump isn't designed to operate 100% of the time. They operate in a stop-start-stop way, which allows their duty cycle time to cool the windings when shut down.
The cat litter containers are clearly incompatible from a material AND ability to withstand high Temps perspective. The copper tubing needs to be closer to 1/2" OD for a Single miner, preferably closer to 1" OD as you begin adding miners. AND, you need enough fluid. so it has a chance to cool properly. Otherwise, you're adding more heat over time than your "system" can remove. And, over time, you find yourself spending more time and money attempting to fix problems, while not giving your miners the ability to perform at the 150% hashrate they'd be capable of, had you just followed the guidelines from the beginning.
My recommendation, going forward, is to heed and read the advisory info from the manufacturer of the fluid, before you set out on an expensive waste of time, money, energy and operating you rig at less than designed efficiency for the sole purpose of peace & quiet along with a patchwork solution for heat removal.
IF you're gonna add miners, then doing what your doing and expecting different results is a disaster waiting to happen. Doubling what you did may cause a quadrupling of negative effects.
Therefore, if you can't Weld and you can't engineer anything, then go onto UA-cam and see look up how to Weld a sheet metal box. If for no other reason then to point to what's involved. Then, look for 12ga to 14ga cold rolled steel sheet. Bring it to a welding shop and ask them to Weld you a box, which follows the guidelines given in the 85 page primer. Make sure to allow about 3/4" between the miner and the side of the box AND about 3" to 4" from the top of the miners to where you want the fluid to be removed. Again, not the optimal solution, but good enough. Just make sure to drop your wider copper tubing between BOTH miners, or else one will be running hot all of the time.
Make sure, if you're gonna use a radiator designed for an automobile, that the tubing on each pass is at least 3/8", preferably 1/2". You might do better using a hvac chilled water style radiator. Except, instead of chilled water, you just use air being sucked at a high enough cfm to provide adequate cooling. Also, building a shroud, which forces the air to flow around the tubes and fins rather than willy nilly goes a LOT further than using a box fan.
Finally, don't use anything rubber. There's a special material they call out, which is readily available and can take the heat the ASICS will be dumping into your fluid. And, I would recommend, at the least, a glass thermometer, which you can leave in the fluid, so you can cycle the fan on manually to keep the Temps low in the hotter months.
IF you were trying to make an entertaining video on what not to do, then you definitely succeeded. If you were serious about creating an educational video, which helps others, then you didn't provide the correct info on what works.
I apologize. But there aren't enough videos on how to properly build an immersion set-up as it is. Your video, while entertaining, doesn't help. Again, I'm sorry.
DJ Hal, you've reinforced my points. Yes, the video was meant to be entertaining, and yes, it was an attempt to warn others about the mistakes that I made, which you pointed out in a far less entertaining fashion. This video isn't targeted at "serious" Bitcoin miners, they'll just drop the coin and buy everything they need. UA-cam is FULL of videos for those guys. My target audience is the guys like me, a dude, doing it for fun, in their garage, and learning a little something along the way. (And, no, I didn't read their 85 page manual, instead I emailed them with the list of materials I wanted to use, and they emailed back that they were fine. It was so much quicker and easier.)
