Each PSU has a J4bberwock breakout and 20x PCIe cables. One of the three has the premium heavier duty cabling the other two have the standard. $125 each.

Those are fun because they're a super awkward shape, and because mains input and DC output are tightly packed together on one end.
Ya, I have a few though from a chassis so I just soldered up a C19 on the AC side and 10ga wire to the dc output. Have a raspberry pi running AWS IoT code to control power on/off remotely. Working on getting the I2C and some other data gathering working now. Would be way easier if there were a decent breakout for them though |

Has anyone bought and done some testing on the single fan batch? What were some of the results?
a loud miner that can run at stock freq 700 in a 71 f room. I did see this post on the s-7 one fan thread Ya, That was probably me unless someone else also ran one that way... still waiting for a day in the 80's to really test out it's ability to handle higher temps... usually the garage gets into the range of 90 on a day that it is ~85F outside But yes it is loud, around the same as the previous S7s. Although I had multiple 2 fan S7s running at the time so it was kind of hard to tell. I have a fourth unit coming to the garage Monday and will likely have to power them all down when that happens in order to reconfigure power. So I can make a good estimate on which is louder then. Well was 88 today and I am sure it was hotter in the garage since there is no a/c and just a box fan in the window the miners are pointing their exhaust at to get as much heat out as I can and the highest the 1 fan unit hit was 66... more hot days coming so I may have to down clock a bit to be safe. Errors stayed at .0006 though so no huge worries. |

can't know for sure as I am not there but it usually sits a few degrees above ambient, it's a garage with a box fan in one window sucking air out and the miners exhausting toward the fan with another window open to let air in. Nothing fancy but it ventilates fairly well. There are two other two fan S7s in there with it.

So outside is ~71F and the miner is holding with two blades at 60c and one at 56c. Clock still 700 and fan at 5400 hardware errors at .0007

Well supposed to hit 76F here today and i have one of these one fan units and two of the standard two fan S7s running in my garage so we shall see how it does. It's at 700MHz currently cause it's been rather cool but I will be watching throughout the day and adjusting if needed. Will post back with what happens.

So, just got the S7-F1 hooked up and running. Temps are low today, in the 60's so I went ahead and let it ride at 700 and it's holding steady at 59c on the highest blade with .0005% error rate. Going to let this go for a bit as the temps will rise into the 70's next week. I will keep you all updated on how it goes. As for the noise it does seem a bit quieter than the others but since they are all on the same rack it's hard to tell.
Also, the packaging was all updated, new foam, smaller box etc... So this was definitely not just a stop putting one of the fans on redesign
what/how does the backplate look like. is it a completely new panel or did they slap the grate over the old one? (can you screw mount a fan to the back?) If possible many of us would love if you could post some pictures of it. If you could get all 4 sides and a few extra shots would be a great addition to this thread. If you have a decent camera please think of this  As soon as I get back to the house tonight I will do that. The backplate looks to be a new panel. Does not look like it will be easy to add a second fan, there are no pre-tapped places to bolt it to anyway... you might be able to take the backplate off and attache the fan to the plate with some washer/nut combo then reattach the plate but that would be about the easiest way I could see of doing it. |

What are your thoughts on the overall build quality? Was it comparable to previous batches or better/worse? I would say it's the same. Time will tell though... |

@philipma1957 That's the plan. Will start it out at ~500 and whatever % ends up being top speed for the fan and then work the freq up from there.
I have pretty decent ventilation in the garage so it doesn't get too hot but we will see. Also may have to wait a bit for a real "stress test" as the temps here aren't supposed to be over 60 F for the next week or so.
Now, if it won't do 700 then I may rig another fan to it... I have a few spares now so what the heck...

Just got my shipment notification so I will let you all know how it is. Should be here Thursday or Friday. It will be running in my garage here in North Carolina so it should be a decent stress test.

I am one of the aforementioned fools and idiots who purchased an S7 with one fan. And I'm probably going to get another.
I have them hosted so this is not an eyewitness account.
I have one S7 Batch 3 or 4, don't recall. It runs at 4.724 Th/s and the temps are 61, 58, 58. Never had an issue. Good miner
The new S7 Batch 16 runs at 4.723 Th/s and the temps are 63, 61, 64. Now it's only been 2 days, but so far no issues.
Are they saving money? Of course they are. Is the miner shit? Doubtful.
Proof that there really ARE many idiots in the forum. For your information, the S7 miner really IS a piece of shit. Then I have made a dreadful mistake. Thanks for shining light on my error cheap talker. Ya, guess I made that mistake too... but then I couldn't bring myself to spend twice the price on a miner that was just as efficient as the S7, on the other hand if I were buying at ~$1k per S7 then I would be leaning harder towards avalon. Mostly for better support of cgminer and the basic virtue of not being bitmain. But none of that matters because the S7 is ~$530 shipped to the US if you can snag a coupon on here and in the days of efficiency and cost being king there is simply no contest S7s all day |

Anyone want to take a guess which way the price gets adjusted? "Price will be adjusted a little this Friday, pay attention to our website for update. All orders that we get payment by Thursday will be shipped out before holiday." This was taken from the Bitmain site just now.

Good call! Thanks for that! Prime eligible too, this is why I love Amazon! |

Anybody ever run into a situation where you are missing a fan in the GUI? fan is on, though at a really low level and cgminer shows no fan for fan1. Bad fan? Bad board? Thanks in advance!
I ran into this problem once and it turned out that one of the fan cables had a spot on it that looked like it had been crushed. I bent it back and forth a couple times and it was good as new. Try messing with the fan connections, or try powering the fan with another power source and seeing if it comes on. I wiggled them a bit and unplugged/plugged it back in but I will check again just to be sure... Think I am going to take this one out of the rack and back home to the bench tonight so that I can test it out |

Dead fan, the other one is moving it. Good point, hadn't thought of that. Got any recommendations on replacements? I know they can be had from bitmain but that takes too long. Anybody see an issue using this fan from amazon? http://www.amazon.com/gp/product/B010EA116C?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00 |
