I bought a 20 Antminer S5.
Order 00120150316111752885y7gx4Lw006AF   ANTMINER S5 BATCH 5 × 8
Order 00120150314212252404W3YFet10064A ANTMINER S5 BATCH 5 × 7
Order 00120150313142123199TBEA7TDx0653  ANTMINER S5 BATCH 5 × 5
All Shipped 2015-03-24.

Only 14 of them are perfectly fine, 6 is not.

1 miner . Yellow LED an BeagleBone Black does not work




2. miner  One board shows temp 0



3.miner. Very confusing error. Mined, but  will not light up green blinking LED..
Someone in factory Scraped off the resistor...




4. Miner.  Ohne BeagleBone Black working onlu 1 hour, and and after it is dead. 
No network, no network leds .




5. One of the miners shows  on one blade  only 5 chip



After only a couple of minutes shows only 6 x



6. Only one blade is working. I get the -----  or  xxxxx . The first few minutes are ooooooo  , but  only half the speed.





Which of these errors go under warranty?

The rheostat. It was too low rating for the S5's fan though, so I'm going to try an actual PWM fan controller rated much higher.

rheo stat extremely hot or s5?

Heh, I actually tried an in-line rheostat, 25 Ohm 3-watt. It worked, but was getting extremely hot, so I stopped after a half hour.
I'll try a high-er rated one next. Maybe get us a way for manual control if necessary.

IMO, a way simpler and cheaper option is to run the stock fan at lower power. something like this for driving the fan at 5V or 7V:



I found that at 7V the noise is about 60%, but airflow is still about 75-80% and its suitable for slightly above stock speeds at room temp
at 5V the noise is about 30% of stock, but airflow is about 55-65%, and can offer about 1.05TH at room temperature with home-friendly noise levels

Read the thread man. I must have said the only real world workable dual fan solution (if you don't have any S3 fans) is to buy two of these fans in a push / pull. Must have mentioned it over 10 times. For one fan setup you need at LEAST a 38mm push with at least 185-200 CFM, max 4000 RPM's. For a dual fan setup you would need two 25+ mm in a push pull with at LEAST 110-125 CFM, max 3000 RPM's. If the ambient temps increase considerably on the dual fan setup some kind of air conditioning will or may be needed. Most other fans cannot take the pressure or keep up with the demand then the Noctua's, hence the 6 year warranty. They are also IP52 rated, which can take dripping water and some spray and dust won't even bother it. The motor is completely sealed of course.

Have fun!!!

The server may have been taking a bit longer to confirm.  Please wait for a response via e-mail.  It may take 24-48 hours, however, please do not panic, the next available shipping date is April 7th so there is plenty of time!

how much confirmation need to change the order status from unpaid to paid?
my order id is 001201504051120225592V0wOzv60691 and i already sent btc to bitmain

Yep. It cost more to use a credit card and a third party website.

Oh and in my area DHL is a crap shipping company compared to UPS.They do not even deliver to my house and I'm in a mid size city. They pass it off to another company to deliver and then try to get import fees  twice. Once on line and once at the door. Watch these guys. Also very slow. In the time it took DHL to get the parcel out of China my other one, shipped via UPS, arrived had been mining for 1 day.

i want to order in dhgate.com
but the price are different.
it cost 407$ to indonesia with dhl 

1 S5 to Indonesia via UPS is $340+$37.82
2 S5 to Indonesia via UPS is $680+$62.44

JUST PERFECT!

No dashes before -- all o's on both blades.  And it was hashing fine out of the box at stock freq for a few hours, then I cranked it up to 400 and it was doing about 1.3 TH nicely.  But so frickin loud.  That's when I decided not to leave well enough alone, and to replace the fan with an S3 push. 

Today its hashing on the one blade at 350 freq again.  And I can see the S3 fan is not going to be enough.  Its barely keeping the one blade at stock clock under 60 degrees...

I did reseat all the power and data cables I can see and reach from the top.  I guess a full tear-down is in order.  What was the good thermal paste again?

Did you only use one fan off the S3? I don't think that is near enough for the heat. You'd need both push and pulls form the S3.

I tried adding just a 104CFM fan to the back of the S5 tonight and use with the stock fan to see if it makes any difference tomorrow after I get a chance to put it in my rig.

Should reduce temps enough to warrant a fan speed reduction. We'll see.

The fan speeds of the S5 and it's extreme heat generation IMO is a downer on this. My SP20's create less heat at much quieter fan speeds. I was hoping to rock a few dozen S5's but I might have to just buy more SP20's unless I find a decent way to quiet them at least to SP20' levels.. 
(I run my rigs in one of my garages under the house. Can't hear it inside, but it's quite loud and toasty in the garage.)
