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

[notlist3d]

Let me remind you, I Bitmain sent a used S5, which one blade was not working, the guarantee of its system, is now the second blade junk has 3 chips began to fall off in the specification of + 5% in 1155 is not included in my more than 7%. Bitmain claims that up to 3 chips normally. Bad Company Bitmain.

Have you talked to the support team?

[marvykkio]

Not sure appears to be down for me  as well.  I also can't get to antpool either.  So likely all of their main sites down.

this was discussed here some time ago.
Apparently, bitmain made a coding error or omission whereas when you simply type bitmain.com in the browser window, it does not re-direct to secure https://bitmaintech.com
The solution is to type the whole https thingie, which is way too much for a regular lazy browser like myself.
I think that quite a few people are annoyed by this.

In short: redirect from bitmaintech.com to https://bitmaintech.com does not work, but https site works

It seem like the warranty center went on permanent vacation.  My Bitmain experience has been great, up until now. 


Are they on vacation?


I have a dead miner, under warranty, that is sitting here.  I'm glad it at least paid for itself.

how? and still be under warranty?
i thought the warranty was 90 days? there is no way 90 days is enough to get ROI. even with zero power costs it would take longer than that.

Here is a good list of fan's including that one - https://bitmain.zendesk.com/hc/en-us/articles/204199879-Antminer-S4-fan-specification-and-possible-replacement-fans

If you are looking at money vs performance I think "Sanyo Denki SunAce 120 9GV1212P1J091" wins.  Not factoring in sound.

I was lucky, I got 4 fan Delta  ;DTFC1212DE-SP07 for $ 36 including shipping

That is a bargain.  Price is what sent me to the Sanyo.  But at less then 10 each that is a deal on delta's.

thats the fan i got to pair up to the stock fan, it flows alot of air.
the fan i got tho was reversed pwm, so i had to make an adapter.

Sure you get long enough wires??.... the ones on S5's connect to the PCB instead of the HashBoards.
Lot greater travel distance for the wire to connect.
Back then the S1 & S3 fans were interchangeable, the S5 killed that.
The difference is about 2 inches in wire length.
You may need to get your hands dirty or buy the fans directly from Bitmain.
Soldering's no big deal but was kind of stupid to omit the hashboard fan connectors.
Just hope they are long enough, then I'll know what to hunt.

Those 4,000 CFM fans ain't cheap, let alone with enough rope...

the wires were perfect length..
the fan i got use a reverse pwm signal. so instead of 0v full speed, and 5v stop, its 0v stop and 5v full speed..

im not sure if the fans he got are the same.

this was the fan i got
