We have made the decision to get into mining and looking for honest and unbiased thoughts.
We have between 8000-9000watts of available and free electricity from 8:00am to 4:00pm consistently everyday of the entire year, however it is unclear if mining for only 8 hours a day is reasonable?
The Seal Miner A2 pro Hydro is very interesting and would be our first choice. Would operating 5x Canaan Avalon Q be a waste of time compared to the Seal Miner A2?
You just need to consider things like network difficulty change, which will affect your ROI time if that’s something you care about. How’s your grid rates? Would you consider buying 2 X 198T Bitmain S19 miners and paying a little bit from the grid? You’d be getting 396T a day instead of 500T and it would cost you under $3k instead of $8k. Or you could underclock them using third party firmware to achieve your 8000W but you wouldn’t get as much hashrate, as a guess probably 300-350T. Just something to think about
@ShredZ , Thank you for your suggestions and I like the way you do your math. The noise is an issue and that was my motivation for the water cooled version. @krypto1369 informed me the sealminer A2 pro requires 3 phase current which is a deal breaker as this building is on split phase and 50hz. (not 60hz). Thank you both for your comments.
You can get single phase miners converted with water cooling plates. Keep in mind that water cooling radiators can be loud depending on the power consumption going through it. Mine has an automatic temperature control so when it gets hotter the fans go faster. If you’re running a 3kw miner through a 12kw radiator on a 20 degree Celsius day then it’s super quiet, but if you’re running 6kw on a 35 degree Celsius day then the fans will still be loud.
Take a look at water cooling plates here, you can put them on yourself or if you’re not sure you can pay someone like east coast asic to do it, he did one for me when I didn’t know how to. Antminer water cooling plate for sale | Zeus Mining
Also keep in mind all these miners that aren’t 3 phase are 240v and will run on 50hz
I have learned that the Canaan Q is a “good for now” miner and might not be worth using after the next having. This means if the Q is only mining for 8 hours a day (my maximum) I would barley break even before it is outdated.
Soon I will have the opinion of an electrician regarding the split phase conversion to 3 phase. This looks like my only available option for mining quietly and with a miner that will be usable after the next halving.
If I have miss understood anything or I have collected incorrect info please let me know.
I have something similar going on with my power, if I’m reading it right off peak is literally $0.03 which is crazy cheap so I’m thinking about getting some S19’s or maybe even a single T17 to test it, but I guess that’s not an option for you, as you have a noise constraint right?
With custom firmware, if you set a power target of say 1500 watts the miner will be quiet because fans will be running 20-30%. Not quiet enough to put in your living room but quiet enough to put in your garage and not know it’s there. Not sure if anything has changed but S19 95T miners are going for $180 usd I believe I saw. But while saying that with the one I had I believe it wouldn’t let me change hashboard frequency or voltage. So not sure if they can be underclocked, but right now after power bill on an 95T you’d make $1 a day running it for 8 hours a day. These miners are made for people with cheap power
The DG Home 1 are low wattage and can be over clock, you can. Plug right into your wall outlets and they are very quite a ceiling fan is louder than them, I have 6 running in my house on power pool getting paid out in other coins if my choice they offer. These miners can be ran without any infrastructure upgrades which keeps costs down on you
@Budgetminer , yes noise is a big concern. @ShredZ , Thank you again for sharing your info and data. @MrMike1992 Thanks for your suggestions.
I will post next week once I hear from the electrician
You can also pull all the fans off and use a Njord board with an AC Infinity inline fan. That will let you run higher clocks and still be fairly quiet. I’m very disillusioned with the speed of miner releases currently causing things to be uneconomic to run way too fast. So efficiency is everything. Go to MiniingNow.com, pick a coin, sort by efficiency. You can probably get an S19 into low 20s with underclocking. @ShredZ would know. If the power is free but noise is a problem, and you don’t want to modify anything, then I would get a bunch of quiet Doge miners like Fluminer L1 or Volcminer D1 mini which are all really quiet and the power to profit ratio is good. Put them on Mining-Dutch and convert to BTC.
If you want to mine BTC direct but still be quiet, I’d get S19’s and underclock with the AC Infinity fan mod.
Then work out what to do with all the heat…
