that many chips with 1 fan??? they're mad.
even with 2 fans - the amount of heat pushed out is quite substantial.
obvious that they are cutting corners now

S7-20160316-700M-1 fan-6000.tar.gz thats the latest FW ...

6000 means 6k rpm fan Huh

hmm afaik max prolly 5k rpm for fan of that size.

normal s7's (earlier batches) will not run if it only detects 1 fan, but have seen EXCEEDING 880deg C & causing miners to auto shutdown.

me thinks mid 70 deg C is still "ok" but exceeding 80C is a little too high.

afaik, chips are rated up to 125 deg C. thats only the chips but other components ? hmmm

most electronic components can take up to 880 C but if more, i smell trouble.

thoughts ?

One fan only, really? Huh

Bitmain cutting corners again, for profit, no other reason. Make sure you get a second fan, if you're buying B16.

But what can we say really. Has anyone actually tested a batch 8-16 Antminer S7 with a one fan?

I agree though that I wouldn't run mine with just one fan either.

Anybody brave enough to test this? Cheesy

Well I keep seeing that the S7 runs a little better at higher temps but I would still be nervous to run the unit with only a single fan. Regardless of what Bitmain declares.

Wow I'm really curious how these things will run with just one fan. I don't know much about the theories of cooling, but the S5 only had one fan and having a second fan didn't really help the cooling that much if I remember correctly.

Received a 115$, also Antpool user only. The mail clearly sstates it can be used to buy a new S7 from bitmain. Ping me if you want the Coupon.

I got the coupon for the same reason but in their mail is declared that it's only valid if you bought an Antminer S7 between the 9th september 2015 and 24th March 2016

Batch 16 S7 only comes with 1 fan... really? lol

Wow thought you must be joking.... Very late in the Day to be making this sort of change. Wonder what they are up to, or perhaps they are just running low on fans?

Well Bitmain is still selling the fans separate so that cant be it. https://www.bitmaintech.com/productDetail.htm?pid=00020160105104607947aoAkWsJK06D0

lol They reduced the price of the S7 by less than the cost of the fan...but took the fan off.

Profit Ftw!!1!

I hope that this is only their way to April fool us Tongue

If it is serious, could be though that they made sure that the second fan was not needed.
Hopefully so, if it is not April fools.

I got two emails says I have $115 S7 coupons available but none are showing in my account yet. I am assuming because they are not redeemable until 4/1?

Yeah I got an email also from Hashfast saying I can get a $115 coupon and I never ordered anything before from Bitmain. Only used their Antpool.

I also just got an email with a $115 S7 Coupon from Hashnest. Only thing I have ever bought from Bitmain is an R1 Antrouter. Looks like they are on a big push, perhaps we are nearing the end of the S7?

Can this product ship to Finland?

Kyllä, joudut vaan hoitamaan tilauksen tullauksen ja maksamaan arvonlisäverot koko summasta (tuotteet+postikulut).
Ei tullimaksua, mutta arvonlisävero 24%

-----
Yes, you just need to deal with the customs clearance and pay VAT for the total sum (products+shipping).
No customs duty, but a 24% VAT.

Ootkos varma että ei tule tullimaksua :/ ?

Olen varma. Olen tilannut 1kpl S2 ja 2kpl S7 Bitmainilta ja hoitanut tulliselvitykset.

translation:
Are you sure that there is no customs duty :/ ?

Yes. I've ordered 1pc S2 and 2pcs S7 from Bitmain and done the customs clearances.

Yep. There is no custom duty for bitmainers in EU area. But you need to pay VAT, which is different in different EU members. In Finland VAT is 24% and you pay it for mainer AND shippment.

If you calculate profitability, be sure to ad electricity transfer and electricity tax to calculation. Not just electricity price.

Yeah, I already mentioned that (see bold).
