Valaki az antminer s9 ről írta

My overall rating is a 3.5 since these don’t deserve a 4. These are great miners that can replace about 3 s7s. However, the miner gets way too hot over the s7s. I can easily run my 5 s7s in my garage in florida at 55% (which I have to because any higher and they make a loud whinny noise) while these are kept at 100% and still get too hot. I can easily keep these at 100% with no whinny noise issue and are more quiet than the s7. If you do want to use the s9s then they will have to be in a much better controlled environment(which I will have to come up with) if you want to keep these lasting longer.
