Topic: HELP - JUST BOUGHT 3x Bitmain S9's - Fan Mod for Noise/Heat and/or Underclock? (Read 2445 times)

Internet shouldn't be an issue for miners, as they require virtually no internet; latency has a slight impact on accepted shares, but it's usually no big deal, although i recommend 1mbps per ~10 miners. You can buy an ethernet adapter on your laptop and link miners up to it; that's the only way to attach it to a pc easily. Splitters should also work well if you do need them.

I want to set up a new mining center in India through BITMAIN AntMiner S9. I am totally new to all these stuff. Shall I have each and every information about the best mining hardware and all it's like stuffs PSU and other things.
I have many questions for this. I am non-technical person.

I will be thank full to you for assisting me regarding me. Any other specialist in touch with you, also you can suggest to ask him or her such guarding questions.

Your every help for this setup will be counted.

My questions are:

what type of internet connection needed to mine through S9? How much 1MBPS connection speed enough or need rather more for this? I want to install multi S9 Hardware and i am totally new to this thing.

Does this S9 Hardware available on Amazon contain any display system? or it is needed to attach computer or laptop?

At present Own i5 5200 CPU Lenovo laptop. Does S9 have Computer attached in built?
 
Can you send me pictures of your setup to my email?

My email is [email protected]

I will be very much thank full to everyone answering my questions.

What else thing needed with S9 Hardware along with PSU?
 

Wait so what would be the extreme circumstances under which S9's could catch fire? There'd have to be no ventilation at all? Or would some airflow with a duct going out the window (exhaust) along with vented intake be okay?

1. Undervolt? What does that exactly mean? I thought you weren't supposed to underpower the S9's...
2. Are you serious?! I'm not keeping them completely isolated - there is airflow - or else the boards would overheat, but an actual fire before the S9's auto-shutoff at 80C? Is that possible? What if I get some fireproof material to cover the S9's (around the material that was suggested earlier that I already ordered) in a dual layer "tent"?

You should just undervolt your S7 not underclock them and it'll reduce the heat/noise. If you keep them under your bed, make sure they don't have any trapped heat which might start a fire.

It can also wrap around duct pipes and duct work.

If you use it with silver tape and staple guns along with down clock if your s9 allows for down clock.

The sound will be reduced quite a bit.

Thanks for replying to both threads! I see what you did... I guess I could get a small shelf and do basically what you did on a smaller scale. Would I wrap this around my duct (pipes) too?

no fan mods .  some down clock if you have the older firmware that allows it.


  this is decent stuff.

you can make variations of the tent I made.

ie smaller  shelf  then I used.

Ok sorry to create a new thread but I have 3x S9's on the way and I need help with noise & heat. I will be running EVGA-1600 PSU's (Platinum) on each of 3 circuits.

-------------------

CURRENT SETUP: For context, I'm running 4x S7's in a dorm right now under my bed and they're decently quiet (with fans and underclock). However, I heard that the S9's are 5-7db louder (stock configuration). Here's my setup:

2x separate 15A/120V circuits (front/main)
2x 15A/120V on a SINGLE circuit

I've messed with some S7's and have been able to run them continuously underclocked at 550Mhz/475/450/400 respectively yielding 4.7Th/s, 3.3, 3.0, 2.7. I plan on building a duct to expel any hot air out the window as this is overwhelming at the moment. Fans are between 50-65%.

-------------------

I didn't consider noise when I got the S9's. So a few issues:

- Heat: shouldn't be an issue after my duct is built; can vent out the window; we have A/C.
- Electricity: should be fine as well; got my PSU questions solved already

- NOISE: What's the best way to deal with this? Insulation? Aftermarket fan mod? Underclock + Fan Underclock? All of them? They would all be going under my bed to help a bit with that.


How loud are the S9's compared to the S7's with insulation/new fans/underclock/etc?

Thanks in advance!!


Edit: I did find a lot of threads on the S5, but not the S9. Someone recommended the Scythe DFS123812-3000 "ULTRA KAZE" (http://www.newegg.com/Product/Product.aspx?Item=N82E16835185054). Would that be good for a push-pull configuration on the S9 as well?

Cost is not a consideration, as S9's cost a lot in the first place. Looking for a straight-up answer for the best aftermarket fans


Edit #2: No aftermarket fans rather; found out it voids the warranty.
