On the box fan thing, just get a standard 20x20 furnace filter and fit it to the input of the fan - suction from the fan will hold it in place and it's a GOOD fit for most common box fans like that Lasko one poster linked. No need for special "fan filters".
The one issue with putting fan filters on the S5 fans it that they reduce airflow noticeably. Good for dust reduction IN the unit, but NOT GOOD for keeping them cool. Better to keep the dust out of the room entirely IMO.

what i think an antminer s7 would be:
5.58THs to 4.68THs
power under 1500watts
price 825 to 975
just my two cents
5.58THs to 4.68THs
power under 1500watts
price 825 to 975
just my two cents
nah, what you described is more like S8 or S7+
S7: 2300-2700 TH, 505-595W in a small form factor. It is much easier to dissipate that much heat vs 1500W
however, it would throw a wrench into plans of many if it would require three separate PCIe connectors with each more than 200W as per S5+ design.
It would mean that Corsair 750 workhorse is a no go.
I would agree more if the S5+ is or was the S6 makes sense that the S7 is for everyone would be more in line around 2.2 th or a tad higher if it is 230 watts per TH that's what maybe 500 watts tops or a tad hgiher as you said , at defaults then goes from there . it would make better sense to have it run on a 110 to 220 line depending on the PSU .
Price it at or like the S3 S5 etc ...that way every one stays happy including them .
if it goes this way i some how see the S8 using less power and more speed if it's a new chip by then .
this is what i hope, they would be unwise to make something that cant run off one psu and is fairly quiet..
not everyone wants to buy something that needs 4 or 5 large psus, and has 8 fans running 5000 rpms.
Thanks Bitmain for creating a next-gen product for home miners!
Sorry, I haven't read this whole thread, but is there an ETA yet for when the S7 will be available?

you could get lucky cost is zip
I think part of reason of making this thread is to worry other makers. They were smart to keep same nm and master it. I think they will be able to make a lot by doing this.
I still wonder on time frame though. Once they get producing them I predict a lot coming fast of the new product.
Well I think with the smaller nm chips there's a huge problem of power consumption.. Intel is dealing with this now on their new gen stuff in the works.. So Bitmain is the winner here even with LKETC and their 14nm.. The power draw from their new chip will be comparable to bitmains fully custom 28nm
Especially when you consider the difference in production cost. It's probably of different magnitude. 14nm could definitively be able to laugh at 28nm in W/GH ratio if properly optimized but i don't think the development cost is going to be able to compete.
As usual, China win with cheap mass production.
Please do not forget TSMC from Taiwan, others from Singapour and south Korea. China is not the biggest....
There are lot's of places with cheap to do the production. But not all the countries really have the buisness's to do it. Producing chips is something not all of the countries you listed I think can do.
China has kinda taken over on a lot. They are just able to make it cheaper with many factors effecting it.
One thing with BTC so low I don't see a reason for them to be rushing to production.

Thank you for your replies, I have them both in my house, ready to use. Im living on a crowded street and I fear the fan infront of the window might push a lot of dust.
@VirosaGITS at what clock you are running your miner(s)?
@VirosaGITS at what clock you are running your miner(s)?
Right i forgot. Freq = 387.5.
Its the second best hashrate for W freq for me but virtually 0 HW, seem a good compromise until winter where i may use the optimal setting which is 393.75. Maybe even try 400 when its winter cooled.
For the dust i recommend getting a box fan filter pack. Its just some kind of net you put over the fan. There's the cheap throw away one or there's high quality cleanable pad that are more expensive.

We should make a bot to request paying address repeatedly to CPU-abuse their VPS... shouldn't be that hard, and that would cost'em money or banning
EDIT: Already tried, it is a fixed set of addresses, shouldn't be hard to track.
Good on you, we definitely need to report the website to the host as they will likely take it down and that will be the end of that.EDIT: Already tried, it is a fixed set of addresses, shouldn't be hard to track.
Now back on subject, does anyone know if the antistatic fans by corsair that a lot use for the S5 with a push and pull method would work if the dimensions were shifted a bit more one way? (A height increase or depth increase) I ask as the only think I could see changing on the design is a bit added in a direction.
I still wonder what the actual dB is from a meter. Looking at the stats, 6 fans running over 4500 rpm should sound like a Ferrari. What corsair fans are you referring to? As my experience with them are not that bright in s5, I simply couldn't use any other fan without underclocking. What I came up with the latest update was to set the stock fan to the lowest rate and put a corsair fan (or whatever with over 2000 rpm, 90 cmf and silent) as pull.
I think i remember seeing they were 70dB fans. So with the added noise of air turbulence and 6 of them, it would not be surprised for 80dB.
I don't think you should use a sp120 here, i don't think it can pull enough Static pressure to make a difference vs the huge pressure from the stock push. However it could add a bit of airflow to the external end chips.
Personally the best way i did this was just the stock fan at lower% with a box fan blowing air on it. Temps are tight together, 57/58 for example. And its much cheaper, support multiple S5 and is quiet.
Hmm, thats another idea I am willing to try. What you mean by box fan is something like this, right?

At what % you run the stock fan and at what mhz? (with getting those temps)
Naw not a fan on a stand, a box fan.
Personally my box fans are in the window and push in fresh air and i use plastic to direct air directly to the sides of the S5 toward the exhaust, but some users just put the S5 on the box fan. I'd probably do that if i wasnt dumping air strait outside with ducts. That plan would probably work if generating heat inside the room was not a problem.
My fan still run at 50% its still summer here, temp does from 55 to 63 when its 28C outside. I think i'll be able to drop them very low during winter.

Well, at first there were 27 available and now its 21. I suspect someone might have sent coins. :/ Leaving - trust too.
Hopefully it's just us sticking them in the basket, and not unfortunate people getting scammed.
