Call it push and pull please. The new batch only has a push.

The picture just shows the suck.
Haha - The picture and the website say it is the same fan (Cooling: 1x 12038 fan-same as Batch 15) which should ~ 182CFM @ 4800RPM, but the firmware says 6000 which would be considerably more and hopefully less wattage.

the S7 fan design is a "suck air" + "blow air" method, no?
which fan are they removing?
sucking or blowing one?
no punt intended

they want to BLOW & don't want to SUCK ! heh
depends how u look at it though, blow to chips but it can be sucking cold air in too but blow the hot air out

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
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 ?
I think leads to problems as you have only one fan working.... no backup. So if there is a failure it's going to get hot.... and you are counting on it detecting it and turning off. The thought of a S7 with no fans running scares me personally.
I would only run 1 if temporary and had another fan on the way, also I would be watching heat like a hawk. I think 1 fan sounds like a bad idea.

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.
Buy a new S7 "for hashnest"

One fan only, really? 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?

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.
March 31, 2016, 07:41:34 AM
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.

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 March 31, 2016, 07:36:19 AM
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.
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?
