Reducing noise S7

[zulu55]

Hello folks!
Eventually I got my S7 shipped, set it up and started mining (PPC not BTC); but!
It's really noisy (I just didn't expect it will be SO noisy), and my place doesn't allow me to handle such noise. I'm living in appartment house (mansions or whatever, I don't know how to translate it properly), so there are a lot of neighbours around, and also it is quite annoying for me, because there is not much sq/m (about 60)
What am I actually thinking about (want to know your opinion and take some advice maybe):
To make a box 1x1x1m, put some sound isolating pannels inside of it on all 6 sides of the box (those pannels are used in sound recording studios http://img25.olx.ua/images_slandocomua/82363553_2_644x461_zvukoizolyatsiya-zvukoizolyatsionnye-paneli-2h1-m-fotografii.jpg), make 2 holes from 2 sides of the box for ventilation tubes (aproximately 15cm diameter) and point that tubes straight into the window. What do you think about this idea?
I think it can help significantly, but I'm not sure) 
Or maybe you can suggest any other ideas how to reduce noise?

Thanks!

You could always change the fans first for the same size but quieter. I think scythe do a kaze fan that fits. It doesn't push the same amount of air so temps may rise (you need to take into account ambient temp aswell) but it will be quieter.

Thanks, I'll research this way. But this also will destroy warranty immediately, that's also the point

Noise comes from the fans!
Change the cooling system and that will improve it!
Also:
1. try changing the fans and if not then change the cooling system for something such as water.
2. Putting the miner close to an open window?
3. Or host the miner at a family member's house and find a way to transfer elecricity to them)?
4. Pay for a miner hosting contract from a place like miningsweden.se (if they accept that)

downclock the freq from 700 to 500 and set the fans to 35%  or 40% if you put it in the tube

then buy this wait for link

Wow! Great, thanks a lot! I'll probably try this)
Let me see is there such tubes available near to me)

[gt_addict]

You don't want one too long though. I tried putting ducting on an s4 I had and the temps actually increased as it didn't have enough power to move all the air in the tube.

Yes, I thought about this too. But I can always cut it) Anyway, I'll try it, this method seems to be good
And there is much difference in s4 and s7 design, where fans are placed, so I think ducting for s7 will be better than for s4

[gt_addict]

Totally agree about the design of them and obviously the fans are more powerful on the s7. It was just a bit of advice to take into consideration  hope the ducting helps though. Don't forget to report back with your findings (including temps before and after).

Yes, I'm curious about temp changes too, hope it'll be fine
I'll report for sure)

it worked for my s-7's

and tube length does some times not let all air clear , but a pull fan at the end of the tube can help.

trial and error will be needed

Thanks, I'll take it into consideration

Best way would be to undervolt it with sidehack's mod. Then it would be almost silent.

[raspberryseltzer]

I used the concept from philipma1957 - 3 separate ducts for 3 separate miners, then have some Y connectors to join them together.  Finally have a strong fan like this one:

https://www.amazon.com/dp/B0130ZAO20?psc=1

... to pull the air out and through a window.  Then cover up the ducts with a few more blankets.

[adaseb]

Can't you just cut the duct into 2 pieces and attach to each end? Putting the miner instead could cause a large short since it looks like that material might conduct, or it might go on fire.

Can you please link or give me some details please, so I could understand clearly what do you mean?

Hmm... Isn't that fan making much noise pulling out the hot air?
I just have 1 miner, so I think there is no need in such a powerful fan

Seems a good idea, but I'm not sure about this, how will this affect noise level comparing to putting it fully in?

I've been in this situation. Best thing to do is put the miner or miners away from the window. I have 2 s7's and I used to place them right next to the window with a fan blowing air directly out of the room. I noticed that it was really loud when I would listen to it from outside. Put the miners at the far end of the room, next to the door and you will notice that the noise will be a lot less than before if hearing from outside. good luck

you can also try putting the frequency to 525-600 with fan at 70-80% you gotta play with it a little.

Thanks for your advice! Tomorrow I'll buy the duct, and the only place I can put it is my balcony, so I don't have much choice) I'll play with freq/fan speed and compare results for noise/temp
