ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH

Which fan do u recommend for replacement for cooling S5. Original one has broken down.

I personally like these:  http://www.amazon.com/gp/product/B00HQ18UDA?psc=1&redirect=true&ref_=oh_aui_detailpage_o06_s00

How do U attach that one to S5 ? Do you remove casing ?

Yes, the casing is removed.  And this fan is RPM controllable.  I'm not sure why the casing is on there.  I'm not familiar with any setup that would use the fan with this casing.  For all I know, it may just be to protect the fan during shipping.

By the way...  I've bought over a dozen of these fans from this seller on Amazon.  They are a good seller.  Free Shipping for that fan as well.

I use them in S4's, S3's and S5's.  I bought more of them to replace factory fans in the SP20's as well.  Of course, I had to buy a different connector to be able to connect this particular fan to the connector in the SP20's...  http://www.ebay.com/itm/161350482183?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

People complain about the 4000RPM "stock S5 fan" being loud - but that 5500RPM version should be good for COOL.

Yup Deltas keep them ql all the time.

Antpool is shrinking in last few days.  I wonder if next gen miners will be coming online soon.

net hashrate has been steadily increasing, so something new is coming online.

[QuintLeo]

I'm pretty sure BitFury has been rolling out their "next generation" for a few months now - but they don't sell to end users any more, just to megafarms like MegaBigPower, so it's hard to judge.

 I'm also 100% SURE Bitmain is rolling out their next generation into their own farm, given their sail of OFFICIALLY "Used" S5 units.

 KnC has supposedly been deployiing their new Solar 16nm stuff for a few months now, but with the massive lawsuit issues and their not selling to end users any more, dunno if they're going to be around in 2 years (and dunno who will end up with their gear if they DO go under - assuming it's still working by then. Their track record on reliability is BAD).

 Avalon? No clue, but no announcements yet even of tapeout.

 Innosillicon? Claims tape-out on their next generation but not production yet.

 SFARDS? Apparently not in high volume production yet, might be having yield issues - though the tech they're using is more proven than any of the 14/16nm options.

[QuintLeo]

All the VC in the world won't help if KnC loses out big enough in the courts. VC firms might be more willing to take risks than most investors, but even they have limits....

I would like confirmation, did the latest S5 firmware fix the chip not going idle when the S5 lose internet connection? The fan would power down but not the chips.

Wondering if i should order those bimetal thermal thing or not.

Looks like second hand S5s sold out. Waiting for some news from Bitmain.

Maybe they just had to ready another pallet for shipping; August 5th shipping -> August 14th shipping.

nope not sold out yet still green here as of this posting.

[QuintLeo]

Not sold out, but VERY slow on shipping.

 Good thing I'm still on high summer electric rate for another month or so or I'd be actively ticked off.

It did but for some it had other side affects like hashing cut in half. or speed dropping to 900 GH .

The entire problem seems to be hit or miss.  I have had an S5 since batch 1. 

I have lost internet before to the unit and did not get this problem.   But others obviously did. I wish we could see what the differences are.

It did sold out, when Rabinovich first posted. Now its green again but it appear to be a different batch (of batch 7). The previous one said august 5, this one says "Shipping starts from August 14th after receiving full payment". This is probably why QuintLeo find it slow on shipping.

That sound troublesome. These second hands are from Batch 7, it makes me wonder what bugs i'm going to get. =/

[QuintLeo]

Nope, I'm not in the "August 14" batch 7. I might have been in the August 5 one though, which would make them "not late" yet.
 (Edit - just got a 'shipped' email with my tracking number, not that I was worried about getting them - just when.)


 Given my current sat Internet, I'd have to say that the "pull the PWM wire to set the fan to 100%" option was a VERY good thing for me - I've not had the fans kick out ever so far.

 I'm not worrying about if the fans kick out if I have a power outage, oddly enough. 9-)

Antpool hashrate is back to what it was before, let's see if it continues upwards from here.

Just got my pair of the used S5s - one of them has STRAIGHT BLADE heatsinks in it, the other the usual curved.

 I wonder it Bitmain finally gave up on that curved sillyness....


 Both of them were pretty clean, the shipment packaging was a little marginal but it worked, a couple of the HS blades were bent up on the bottom but that's pretty common and easy to fix....

I see, they work well performance wise? I am supposed to received mine tomorrow. For some reason, having to pay import tax for UPS is an "unexpected issue" and that delayed it to tomorrow or something. Well whatever.

I might try your pull the pin trick to get 100% fan at all time, maybe not, the melting issue is supposed to have been fixed and there's manual user control fan firmware out now. I will of course test that and also cut its internet to see how it reacts.

If i can keep the fan speed dialed down just a bit and it doesnt wind down when it lose connection, i might go for it.

Same here, had to pay $33 of tax... go figure
