Topic: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH - page 208. (Read 528055 times)

I bought some very similar ones from a guy on eBay:

http://www.ebay.com/itm/bitcoin-antminer-s1-s2-s3-s4-s5-s7-zeus-lightning-thunder-fan-air-duct-/252171861712?hash=item3ab69d3ed0:g:vbkAAOSwPcVV20xa

The price is good and the quality is very good also - he definitely has a better touch than I had with my Reprap. 

Is there anymore of the 3D printed fan adapter for sale?

Is there a 3D print file available online?

Not all of them can do it.
One out of two B2 that I got likes to be at 575/4.64Th, can't really go any further.

So I have three S7 (two at the office one at home) and for the home unit I purchased one of the 3d printed fan adapters on eBay and using electricians tape I affixed it to a dryer vent that exhausts the hot air into the hvac ducting in my house.

Having it at 40% fan and in a spare basement bedroom/office it successfully ducts the heat upstairs to the three bedrooms above and it stays mid 50's to 60 temp with the cool basement temps

First pic is the printed adapter I borrowed off the eBay listing

doing what Philip did. 606 frequency is killing it batch 2. 4.9 average

That is exactly what I saw when one fan died within a few days of delivery.
I had placed the new firmware 10/23
Fan died and hashing stopped.
Only way I could fix it was by replacing the dead fan.
I think that is an excellent feature.

Are new ant miners worth getting hold of these days given the fact of MH to kwh to cost in UK? Any improvements over how much power is being used on s7 1042 watt is that running at full speed at 100% load or that under volted to produce or that the default it has when shipped mining at 4TH. Can the unit be powered off 2x 750watt psu or need special PSU or high spec?

i found and solve my beeping problem. Problem is; i modified my s7 and make a single fan so, stock s7 firmware hasnt got a Fan connection control but new firmware 23/10 has. we must to connect min. 2 fan (fan1-fan4) for new firmware  finally beeper works his job and beeping very loud. i found my solution on my kernel report. then i decied to make a single device with 1 controller. but i would make a trick for controller 1 fan send to twice controller fan plug pwm signal. i dont do that.



you can configure missing beeper checkbox like this.
open miner configuration page press f12 then find id=beep then double click style="display: none;" delete it leave it ""
press enter finally beeper ringing appears on your page. do what you want and save apply.
(but this is not only 1 bug, another bug is this config is resetting with your frequency change. i said this 1 years ago for S4)
i dont recommend disabling beeper but when a pool down this ring like a hell.

beeper works this problems:
-pool down
-internet down
-fan down
-temp high (over 80C) (this issue is over 79C, everyone says my device is not hashing or stopped because it is.)
                 and also some lm75 temperature chip send faulty temperature data to controller.



this unit : 9.1Th 562Mhz Fan%54 170A 12V - 2250Watt from Wall

and i also shared S4 J7 Chain1 Problem Solving Procedure, like i promised, sorry for delay

agree -- most good brand PSU last a long time due to better quality components - 1 year lifetime is very short and should not even be sold as PSU - just my 2 cents

All the Corsair PSUs I scored were rated for 100k hours = 11+ years 24/7.

evga 1300 has 10 year warranty and runs S7 just fine with two extra PCIe extenders (each cost $4-5).
You can find used for $120-130 (no warranty then) or ~$170-175 new (it even comes with a jumper in a bag, so you don't have to make it or purchase separately).

PSU not lasting a year?

I have all Bitmain PSUs for my S5 and S7s

What's the MTBF for reasonable good brand PSU?

Agreed, about similar area as the northeast but I like the shape of the trees more in the northeast and northwest [More like Christmas trees].  Yes, plenty to do outdoors around here.  We have nice State parks, lakes, hunting, etc.  We are located at the foothills of the smokey mountains.  Houston, is a bit flat with as close as it is to the ocean.  Although, I don't mind flat when it's close to the ocean.  I just got back from vacation in Naples, Florida and Marco Island, Florida.  Quite flat down there.

OT: Houston here, but we have a similar area up north a bit-Woodlands (name speaks for itself)-great for families w/kids, lots of space.

Hoover, Alabama

yeah, I second that...I would like to live in a more wooded area. Which state is it (somewhere North East)?

I wasn't leaving it up long.  Only wanted to leave it there about 30 minutes or so to disprove the previous statement about home mining being over.  It all depends on how far one is willing to go with managing noise.

Also, don't believe the hype about PSU's lasting no more than a year.

Totally off topic... but you have a beautiful house

"For sure my wife would not let me keep the S7 with that annoying loud howling sound so I had to come up with a solution."

Unless you go watercooled the S7 is not a good idea for home miners, imo. Seriously, what are you guys thinking with your homemade tubes and extensions, they are a serious fire hazard. Let alone the noise pollution.

The extreme heat these monsters are releasing have marked a red line for me. The chance something is burning or melting, as demonstrated with pictures in other threads, is warning sign enough that home mining has reached a limit. And 1200 watt PSUs, do they even last for more than a year 24/7? They are also damn expensive.

Designwise, I don't like the entire single heatsinks on the back of the S7- many have reported them to be falling off. Back in the days of gpu mining you were better off with an AMD 5870 than 5970 too. It was just too much of a hassle to get them cooled and running smoothly. The 5970s often died prematurely, no wonder.

Until something has improved, the S5s are probably as high as I will go until the (final) end of home mining in August 2016.
