Quick look at Octotank12 and 2 whatsminer 30s+

I’ve got an Octotank12 and two Whatsminer 30s+ on the way. No pics or videos yet since the Whatsminers are expected to arrive in about 10 days. The Octotank12 should show up in roughly a month. Big shoutout to mikeywith for hooking me up with two Whatsminer 30s+. And thanks to redpanda for a $50 discount on the Octotank12. I paid 1500 + 543 50, so that totals to 1993. For the two Whatsminers, I dropped 3203. Not sure how import taxes will hit me, but so far I’m at 5196 total cost and expecting to hit 196 TH. I’ll keep this thread locked until the equipment gets here.

This looks to be ideal for the home miner with use in someone's garage or basement. Not to sure I would put this in the living room however. Wish that my residential power was cheaper, I'd be a buyer if it was!

It has a lot of options. It can hook up to your pool in the summer. It may be able to heat hot water tanks. Our mine has 100kwatts of spare power. if a tank pulls 6kwatts we could do at least 12 maybe 15 tanks. Thus 12 x 200 = 2.4ph And if we use m50s++ 12 x 250 = 3.0ph

Hong Kong so maybe I get it by 12 noon. this will be 2 x 98 = 196 th the cooler will come late feb or early march

gear is here. I will dry air test these in my garage. First one is powered up on normal. 96 th as you can see the middle board is a bit low. but not running for a long time. I will give it a 3 hour run on normal then test low and high speeds. My thanks to mikeywith for helping me to get this

That looks cool!  I'm very intrigued at this minimalist immersion cooling setup.  It's what I've been wanting for a long time possibly.  I'm looking forward to reading more about the experience and your take on it.  I wonder how this compares to a liquid cooled Antminer.  I see that it can operate in 104 degree environments which leaves it just out of reach for being outside in the summer where I live, but I think for people living in most places this might be a decent outside option.  Nice find.  Now to wait for some pictures.

Glad they arrived, you can not test the high with air cooling, low will work fine and cool, also you can download whatsminer tools and set power limit for each miner, like 3000w it runs a lot cooler with reduced hashrate.

I will likely set them to 2800 watts as the cooler is supposed to do 6000 watts max. update. I set to normal speed and used the whatsminer's tool to lower watts to 3100 or less.  results below: So I save 300 watts and drop from 96.0 to 93.8. 2 at this setting would likely be to hot for the cooler. but I do know that setting on low does 88.1 and 2850 watts which would be good for the cooler as 2x2850 = 5700 which is under the coolers 6000 watt spec.

Keep in mind the low power mode will tune every miner differently, also, inside the tank temps will be a lot lower and thus the tuning might go higher because it does use temp as a measure of how low/high the frequency goes. Long story short, using the power limit is safer when you really want an exact watt per miner.

Okay this below is 'normal' with a 3050 watt cap total of 6100 watts which would be too much for the  cooler if it can do 6000 advertised number.

Yes, you want to keep the power mode on normal when setting a power limit on the miner, it's almost impossible to bring the miner to an exact figure, so your 3050w limit will usually be slightly less, a few watts here and there, also, the power consumption on the tool isn't 100% accurate, so make sure you use a wattmeter to get the exact correct number. I would also look for a different tank, 6kw is too much for Antminer and a bit on the low side for 2*Whatsminer, but at the end of the day, the lower you go on these Whatsminer the more efficiency you gain overall. Also if the project kicks in and you want to sell the package as a 200th miner you would want to get the M50, they range between 25w/th to 28w/th, the lower the more expensive of course. The M50s 110th 28W would be a good pick, it should do 110th at 3080w default, so if you want it to stay at 2900w (to not go above 5800w for the tank) it will do 103th or a total of 206th for the tank. Meanwhile, keep in mind that you will remove fans in the tank, the reading on the wattmeter will take the fan readings too, the fans in the pics you posted are running close to full, they consume about 85w each at full speed (7k rpm), so the reading on Whatsminer tool will be a lot more accurate when the miners run in the tank.

I don't mind if I am short of 200th and end up selling a 180th machine burning 5800 watts.   The key with the unit I am using is it is a 2 whatminers piece. The cooler has the ability to heat in the winter and warm a pool in the summer. My partner "buysolar" has been doing solar setups in New Jersey for 20 years. We may work the angle a few ways. Also we may do a single whatsminer m50s+ overclocked if they supply a proper psu to do that. https://www.whatsminer.com/src/views/product_details?id=15&name=WhatsMiner%20M50S+ what matters down the road  is how good the cooler is. It could be a bust.  which is why we got the m30s+ to test it just in case we don't like it. what I have found interesting is: 'normal' and 3100 watts = good 'normal' and 3050 watts = good 'normal' and 3025 watts = testing now>>>> edit :  now doing: unit 1 >>  92.509 th 32.56 watts a th and 3011 total watts unit 2 >>  92.490 th 32.62 watts a th and 3017 total watts 'normal' and 2950 watts = fail 'normal' and 2900 watts = fail this is not to complain but may mean the cooler will struggle with 2 m30+ on normal and 6100 watts. Typical designed just a bit wrong and yet they push 2 whatsminers as a fit with the cooler. Likely need a quart more liquid and a little bit bigger radiator to be perfect now on low setting I did 88 and 2875 watts which is 32.67 and 2 of them would be about 5750 watts. so low setting may be needed for the coolers. I will post back to see if I can play with settings a bit more. Maybe with a day of burn in I can set lower than 3025 watts on normal.

Where does it fail when you set these numbers? Also, looking at the tank you posted it says 12kw cooling capacity, no mention of the 6kw, which means it can safely run two MicroBT even overclocked, unless I am missing something.

you are correct misread it. SALE! NEW PRODUCT OCTOTANK 12 LIQUID IMMERSION COOLING SYSTEM 🔍 "OCTOTANK 12 $1,399.00 - $1,499.00 Miners Supported 2x MicroBT Whatsminer or 1x Antminer Input Power 180-277 VAC Maximum Input Current 60A (MAX COOLING CAPACITY 12KW ) Networking RJ45 Port (POSSIBLE TO UPGRADE TO WIFI) Security LOCKABLE TOP (SPECIAL BOLT KEY) Operating Min/Max Temp -30C TO +40C / -22f TO 104f External Dimensions 40x40x120CM / 15.7 X 15.7 x 47.2IN / 85KG Additional Features IP54 WEATHERPROOF. SAFE TO USE ALL YEAR ROUND Internal Tank Dimensions 321 x 244 x 580 mm 12.6 in x 9.6 in x 22.8 in" please note info  in "..." is from octminer's website good then this is better than I thought. It will cool 2 m30s+ with ease. Even if I run them at high speed.

That is good news then, you will be limited by the PSU's max limit which I believe is 3800W, so for your two M30s+ you should get anywhere between 110th to 115th without going past 3700W on each, so that be a total of 7400w which is slightly above 50% of the tank, and 220th-230th. For a medium sized house, with the correct engineering, those 25k BTU hour should keep the house warm in the winter, while generating nearly 500$ monthly, not sure how much folks there spend on heat during the winter, you are going to have to run a lot of maths.

Can the real whatsminer website please stand up? Im looking at joining you in this adventure,  2x whatsminer in the octo tank! https://microbt-whatsminer.com/product/whatsminer-m50s-plus/ Is this legit site?
