The model is Antminer S19j Pro 104TH/s, 3.2kW, bought from ebay from a guy in Croatia. I should've bought the avalon Q indeed, once i complete my setup i might get it
What do you mean by bitmain miners are failing a lot? What is meant by failing?

Also how do you handle the sound from these miners? Do you just keep them away from where you live or is there some nice methods to isolate them but also keep the air flow good so they dont overheat?
Do you use thermostats or any other monitoring methods for the temperature. I just saw a video in youtube of a guy dismantling a bitmain, removing the fans and setting up hydro cooling system.. however the sound didn't change as much as i would like to (heard it in the video)

cost of miner and Electricity costs?

I reccomend you sell it and use the proceeds to buy avalon Q.

3200W give you 104Thash gives you 30.8J whereas Q gives you 1674W at 90T+5% at 18.6.

My miner mini 3 does not make any sound. It is silent. nano 3 makes a lot of sound.

If you want to reduce noise then you would have to reduce power.
