New one fan S7

[notlist3d]

Yeah, like they tested S7 heatsink design in S5+

And the 3 hashing boards per miner they tested in them, which I have actually have groan to like.  Took me a while to get use to it but at this point with having big PSU's around and 240 I kinda like the power of having 1/3 more in each unit.

Only thing I wish I could get them to do is use RPI's as controller as easy to get replacement and sd backup is so easy.   But I think BBB are here to stay.

They say 1 fan is naturally more quiet than two fans. Since fan noise is greatly dependent upon rpm, I wouldn't say, that one fan running on higher rpm is necessarily more quiet than two fans running on lower rpm.

If they are using good thermal adhesive and a good fan, it ain't impossible after all.
Avalon 6 comes with a one fan and at least my temps are at reasonable level.

yes it is tru the avalon 6 has 1 fan but it has huge massive heatsinks. It also pulls 1000 watts or less at the ac plug.

the s-7 has 140+ heat sinks  and it pulls 1400 watts or more at the wall.

Like I said in my case I have lots of fans so it is an easy fix.

But the price drop of 7 dollars is insulting.

It should of went to 560 not 575

sidehack has a good point  if your mining room is 70 f  or less you may be good  but if you have a 90f or more room you will suffer.

Comes down to drop the freq from 700 to 600 maybe 500 or add a fan

Bitmain really did cut the price down to the bare minimum... maybe next they'll take the stickers off and save a few pennies on their future miners. Yeah, the boards will probably run real hot and it'll take either a cold room or a freq frop for them to run at a good temperature. I'm sure most people will just install their own fans so the 1 fan won't be such a big problem. Looking at the S5, it's also running on only 1 fan so besides slightly higher temps the miner probably won't suffer.

I have ordered 5 S7 miners of the 1 Fan.

Delivery is fast to my area.

Expected delivery is Thursday.

Fingers crossed

[sidehack]

Yeah but the S7 generates 2-2.5 times the heat of an S5, so that's by no means a valid comparison.

590-620 watts  vs 1300-1450 watts

pretty big difference.

I just think the fan will move at 5200rpm nonstop

 and people will need to downclock.

I would buy one from them at 560  but not 575.  My stock of add-on fans would work.

I feel the drop from 582 to 575 covers the diff and the price moves but not the missing fan.

price truly needs to be 560.  I have 34 coupons sitting in my account.

34? yikes, shoulda sold those if you're not planning to buy a s7. maybe the price will drop a bit more and you could take advantage of the situation.. or resell them and make a profit. people are buying for 650$ still on other websites like amazon and ebay hopefully none of these overheat or the fan isn't too loud, waiting for a few reviews and even then i'll only consider buying one of these.

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.

Still doubtful about this new miner, keep updating us about it. I still don't trust this new "wonderful" price that Bitmain has given us, something smells awfully fishy. If there are issues soon, tell us about it. Otherwise i'll go fish myself a coupon or two and buy one, it'll be nice to put a few s3s out of my rig and replace them with a single s7.

Proof that there really ARE many idiots in the forum. For your information, the S7 miner really IS a piece of shit. I have a few S7 and some Avalon 6 miners. A6 is a much better built machine. S7 is junk, in comparison.

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

All you greedy f&ckers are being f&cked in the a$$ by Chinamen Bitmain, hope you njoy it!!!

I have a few I'll give away if anyone wants one.

This is an incredibly cynical move. This move is worthy of the shady Dan Ackroyd SNL character who used to market products with questionable safety profiles. Especially coupled with the coming northern summer.


 BM is essentially factoring in that the useful life time of this miner will be the shortest of any previous model.

In addition to the higher fan speed previously mentioned, with one fan, a failure of an individual chip heatsink would be catastrophic.  Now you have to wonder about how much of a fire hazard this thing is.

A potential cheap bandaid might be this ebay gizmo: http://www.ebay.com/itm/AC-110V-Digital-C-Temperature-Controller-Temp-Thermostat-Control-relay-Sensor-/380665672071

The relay in this controller could be use to either power down the AC feed to a network switch or switch a relay which directly powers down the miner AC feed.

I also don't get the business case. So let's say you save $5/miner. Say the your miner cost is $300. So you are betting that any increase in this one fan miner warranty return is less than 1 in 60?


From an informational standpoint, this urge to push out miners and not be concerned about the long term reputational impact? Very strange.

[navigatrix]

Made to think about it.
The coupon can be used by others?
Anyone have a coupon it will not use to give me?
This is for the science and the test! hihi
seriously, It will be great.

I have several coupons that I will sell for .06 BTC. PM me if interested.

[nexus99]

If Eligus will ever pay out I will buy one of these... S7 that is.

[suchmoon]

I have several coupons that I will sell for .06 BTC. PM me if interested.

hi,
yes I'm interested but how does it work?
it is possible to use 1 for each machine?
2x antminer s7 = -230 usd
or
2x antminer s7 = -115 usd
?

AFAIK the coupons for physical Antminers are $100, the $115 ones are for Hashnest.

And yes, you can use one coupon for each miner.

[Entropize]

I've got some coupons, PM me an offer for them.
