Topic: Reducing noise S7 (Read 1974 times)
My main farm area with 16 s7's in it in summer runs 85-95F ambient and the miners routinely have run at 70-75C running full speed 24x7x365. Zero problems and they batch-1's through batch 16's.
Why not just put both tubes outside?
Wonder what your neighbours will think when they see that.

The highest i've had my s7s is 70 temp, and when that happens I lower frequency down to 600-650 and leave the fan at 100% and it brings it down to 64-67. My miners stay around 60-67 all day, but when it sometimes reaches high 60's i will open the door that the miners are in and it usually drops it down to 62-64. I've had the miners for about 3 weeks now and no problems.
edit: saw your second picture, make sure to add a back up pool just in case the primary pool server goes down.

Thanks!
So my temps are ok, that's good
Yes, I'll add a back up pool, thanks for mentioning

So, I've performed ducting and noise reduction is pretty good
Firstly, I want to mention, that my tube is different from what Philipima1957 advised me. Its' isolating layer is thin (actually I expected it would be twice or triple thicker - 2.5cm), so tube itself didn't reduce noise much, but I covered it with 3 blankets and then it was a significant noise reduction, so now I'm in the room next to miner and I don't hear it at all, working on 100%
I placed miner and PSU fully inside the duct, cut a small hole in it for PSU wire
Pointed out of the duct into the window, so it is pulling air from room into the window (I've done visa-versa at first, but is was not a good idea)

Not very esthetic, but effective
Now I run it at 700mhz freq and customized fan speed and temp results seems to be normal (as I was told by seller - 62-68d.cent. is ok)
https://s31.postimg.org/3p8kwau57/stats.png
It occupied one room but I don't use that room at all) Local temp in my apartment is ok, as it should be at summer, miner doesn't affect it now, and noise is not heard almost at all.
Question is - is 62-68 temp ok? Is that bad or not to run it on 100% in the duct?

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.
yes he can do that

out<<< Miner--Pcie----Miner <<<
Above would be fully cut tube 1 miner
he may find two tubes work first tube 3 feet second tube 6 feet both tubes go over the miner up to the pcie wires.
I have done all those methods along with an small down clock of freq and dropping fans to 40 or 50 %
I like the insulated duct idea but will the whole S7 fit inside it? Also is it a fire hazard if its inside and gets too hot? Let us know how it goes OP, and please update with pictures. Thank you.
search for the sidehack s7 hacking thread. You however need to buy some microchip programmer dongle. So try the tubes first and let us know if it makes a difference.
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

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

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

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
Best way would be to undervolt it with sidehack's mod. Then it would be almost silent.
Can you please link or give me some details please, so I could understand clearly what do you mean?

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

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).

I'll report for sure)
