For reference each 12038 loads at ~1.9A at 4000rpm, making each fan up to 23W.

12038 is just a generic reference to 120mmx38mm fans, it's not a specific model. I was under the impression the fans were similar to the AFC1212DE 3900RPM fans which draw 3.0A max each. Not that this is remotely on topic or anything.

AFB aren't focused flow, they're FFB something-or-the-other or one of the FFB derivatives.

Bitmain announced IN THE SAME ANNOUNCEMENT where they announced the S7 that they were working on another chip - I forget if it was 14nm or 16nm offhand. They have also in the last couple days mentioned that they would have information on the "upcomming S9" soon - but since they're not selling off "used" S7 units yet I'd guess at least another month perhaps 2 before they even think about starting sales on the S9, except perhaps on a pre-order basis.

Given their roll-back on the efficiency spec of the A4 and the miner based on it from their original announcement, and that they were working on it at the same time as the A3, I suspect it turned out to have similar efficiency to the BW.COM LK-1401 chip rather than being a "new ground breaking" level of efficiency like the BitFury chip.

It's also possible that the LK-1401 is actually the Innosilocon A3 design, given the long-standing relationship between Innosilocon and LKetc (which owns part of BW.COM), but that is pure speculation.

Got a link to this BW.com Huh

these guys are huge, just ya site hard to translate, but 14mn announced from them in 2015

they ran preorders from 2015, should be hashing the 14mn now. their impressive chips, check their site Wink

Practically the B16 has the same specs as the SP50 (from October 2015) with the only difference that you can not buy the B16, so i do not really trust in the model from BW.com --> Renderings are nice but i personally prefer real, existing physical gear Wink

TRUE! so little known about them, and yes it dosen't look like they actually SELL any hardware to outsiders (tho i can't get thru half the site ;p)

Why do you suppose gold wires will increase power efficiency?

While gold is not as good a conductor as copper when clean, it does not tarnish and so remains very stable at power conductivity over time. Almost all other conductors (aside from exotic supeconductors) degrade over time do to corrosion.

It's listed as a repair because the volt-setting circuit has been known to shoot craps, but many would consider it an upgrade.

I'm assuming you'll want to hack the regulators on later batch machines and get about 25% better efficiency?

Is that possible?

ya BW has has 16mn for a while, and SAY they have 14mn too. wish their site wasent imposible to use, as they are other best option out there for little guy

It is a generic reference, which is also what Bitmain calls that fan. I had the data sheet at one point but I can't seem to find it now. The fan you linked is full rotor with no 'prespin' so uses more power.

I was estimating 2A per fan. I do have some 3A fans around, which do bear a resemblance to the S7 fans, so they could be running hotter. I've not put one on a meter to test but it shouldn't be too hard.
