Are ASIC miners very noisy? I would like to buy...

[digitalcitizen]

I would love to buy a couple of second hand miners, BitMain or another one, Avalon?  I am not sure what the best ones are, but I gather they are quite noisy aside from being electricity suckers, but I have a source of electricity elsewhere, and to keep them cool.

Does anyone have any advice on the less noisy miners and what the best second hand ones are to buy for a new miner?

I'm buying GekkoScience sticks for home, but the ASIC for the farm elsewhere.

Thank you

Buying second hand ASIC have some risks, but i'm sure you know that.

But, rather than looking for second hand miners based on noise, you should look for efficient ASIC and ways to reduce it's noise.
There are few threads about reduce noise such as I need quiet in my house! Sound control techniques for S9 miners? and Hobby Techno's Soundproof Box for Antminer

The antminer ltc 3+ is not too loud if you downclock a bit and lower fans.

But this is btc section.  The Avalon a841 is not real loud with a downclock look for my review on it in hardware section of btc.

Do you have a source of cheap electricity? That is a huge factor in what gear I'd suggest.

If your looking for a ball park for Asic noise levels between 55-75 DB is a pretty good range to use for an idea.

Like Phil said the Avalons offer a lot of flexibility in downclocks to reduce noise/power, some models also had a recent release of efficient firmware. The 841 for example with this upgrade is on par for Canaan most efficient gear and can be found for a decent price.

Again depending on your setup, we could probably offer more direct advice or suggestions.

There are some ASIC miner with less noise or noiseless miner I don't think if you can buy them in second hand but if you have enough budget you can directly buy hydro s9 which is noiseless miner from Bitmain.

Another Bitcoin miner(sha256 algo) with less noise is 8 Nano 44TH from ASICminer according to AsicMinerValue from here  the noise level of this miner is around 47db which is pretty low noise compared to antminer s9.

Another low noise ASIC miner that I know is Zeon 180K but this miner is for equihash algo but still, this miner is one of the top profitable miner these days much more if you can get a free electricity source.

You want a quiet miner with decent speed, think used Avalon A71's. When undervolted/under clocked using --avalon7-voltage-level 9 --avalon7-freq 525 --avalon7-fan 10-30 they make perfect home & office heater pulling around 750w from the wall. Most of the time the PSU is louder and speed is still over 5THs. Find a super quiet ATX PSU and could even be used in the bedroom.

Could use a high end desktop psu with 1200w if looking for quiet psu for in home for 1000w or less. There isn't much that is "competitive" anymore for in home mining that is quiet though, imho. Just older hardware.

the nano miner is a scam  do not purchase it

Thanks everyone!

I really appreciate the advice, and I'll go ahead and do some more research.

I'm not expecting massive hash rates, just a place to put some miners where they won't be too noisy.  I can handle the electricity.

What I want to do is just place them somewhere and handle the electricity costs, which aren't much because there's a lot of solar out there where I'm putting them, and run them 24/7 or just when I want to for periods of time, and rent out a modest hashrate on NiceHash.


One of the miners will be to contribute to a new pool.  But first the miners and quiet PSU.  I will see what I can find based on the advice.  Thanks again.

By the way, what sort of Internet connectivity do I need or other device so I can control them remotely?  Connect them to a router of some sort, and allow my IP in so I can SSH to a control panel of some sort, if the router is made for connecting the miners?  Otherwise I suppose I would need a desktop there, router with some ports, if they plug into ethernet ports, and keep the desktop going so I can SSH in and control them from where I am.

That's a basic intro to mining thread that may help a bit.

As far as access to your miners if they are in your same home network you can access them.

If you set them up in a location further away that can not access your home network, then I think you have the right idea of having a PC, maybe even a pi set up so you can remote access in.

There are also some mine management programs you can use, I think this allows you to bypass the need for a pc/hmi  set up at the farm, but you do pay a bit for them.

I have not had to run a remote farm so this is not my forte.

Hi, thank you.  That thread has been very helpful especially in terms of electricity and pulling amps.  I will have to check that out further, but I'm good so far for one or two miners as a little hobby project until I can scale up a bit, and run them every now and then for a day or so.

I've chosen some GekkoScience sticks to order early next week, just so I can watch them and see them working.  And an Avalon to begin with, I will start small and steady with the other parts I need and try to make it as quiet as possible.

Thanks again, that thread was very informative, I may have found out the hard way.

Cheers

These fine gentlemen gave you a few options of a lower noise miners, but make no mistake those options are just generally less noisy than the others but they are no where near quite/silent !

depending on where you going to place them and how sensitive you are to noises during sleep and such, but in general asic miners are just noisy. reducing the noise will result into either lower hashrate or some expensive silence tools which will extend the period of ROI which is already too much nowadays.

my advise if you are going to buy asics then noise should be the least of your problems, look for ROI in the first place. if you have cheap power source then you could buy some S9s, they are liquidated and selling for about or under 200$ including PSUs.

do more research as mining is a risky business, it is not easy as it seems. invest more time learning and reading about it and invest wisely.

Good luck.

Wow, blockforge have a sale on Avalon miners.  They also have BitMains.

And they have a couple of presumably decent second hand ones.  I will have to look into that further.  

Thanks also mikeywith, the miners are actually going to be right down the end of a homestead, where nobody goes except to walk in and out of a door here and there.  So even though the noise I understand will be high, I can try this out with one miner and I am sure it will be fine.

The noise is unlikely to reach the part of the house where everyone lives and sleeps, there have been plenty of noisy and annoying things to try out and confirm some preliminary results.  Just in terms of noise so far.  I will probably look for a ROI a little later on, I probably have a steep learning curve.  So I will absorb the costs and such for a short while and reconsider my position for ROI.

Thanks so much everyone.
