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

[notlist3d]

Just unboxed a couple S5's I bought a while back and found one of them had obviously been used excessively.  It has soot all over the heatsink.  I have submitted a WTF email to Bitmain...I guess they really are going downhill

Let us know how it goes!  That was not the "2nd hand" unit was it?  
It was still a batch that showed new right?

Bitmain has been doing this for quite some time now - Passing off obviously used and dirty units as "brand new". I've received dirty and used "brand new units" myself.

It had been a while since the last "batch" of miners so they were plugged in for quite a bit compared to earlier batches I think.    The raising of prices made less sells I think and then the batch kept lasting.

And I do give them credit to mark these right now as 2nd hand.   They have all been run in a data center for a while, so the status change of new was the right thing to do.

I'm not unrealistic I know they need to be running and cant sit in a box.  But I like the more honest status change.

It could pad the margins, though.

margins? Very last S3+ (brand new) they were selling for around 200USD and S5s is much cheaper in production

yes but the s5 is twice as fast and uses half the power.. so that means its worth twice as much. :/

I don't know if I go with the logic on this. It also depends on hashrate of network when you get the product.

Twice as fast with more energy savings does not always equal worth twice as much.  There are a LOT of variables.

Talk about signature campaign spam and necro posting ....

If any rig is twice as fast as another, not only that, but uses half the energy to deliver that hash rate compared to the other, then it is as clear as daylight that it has to be, arguably, twice as expensive, if not more.

EDIT: And no, I refuse to feed the troll.

If they were released at the same time... then yes it would be true.  It was mentioned "Very last S3+ (brand new) they were selling for around 200USD" so it's been quite a while since there were brand new S3+.  So I'm assuming were talking about two different points in time.

I could be wrong but I don't think S3+ and S5 were selling at same time.  So variables such as difficulty among other things is a factor.  (Not sure on S3++ it might have been selling at same time as S5).

S3++ was S3 + that i remeber was not but I don't think bitmain ever sold any S3++ to the gen public you had to catch those on a ebay sells and had to notice it .

Also received some obviously used S5 units about a month and half ago.  They are at least performing at their rated hash rate, but still should be listed at the very least "used".
Cleaning the heat-sinks are no easy task either.
One very early batch I ordered when S5 was first sold, run around 10c cooler in the exact same environment, and have less dust on them than the "new" ones ordered.  No cleaning have been done to them either.

The normal English definition don't always apply within the realm of Bitcoin. "New" doesn't mean unused. It probably means not previously sold, and comes with a warranty. "Pre-order" sometimes means you have invested in the company. It doesn't always mean you are a customer. It might also mean "you are a fool".

Did you just clean heat sinks or repasting to?    Cleaning heat sinks is not terrible in itself.

But after working on a C1 and 4 boards with I can say thermal paste is a lot of work.  If you clean it properly and then do new paste just takes a long time.

Real miners have compressors for that purpose - you need to blow all dead critters from those heatsinks and fans once in a while anyway, at least before selling them on eBay

I've seen a pressure washer used once too although I wouldn't recommend that.

But receiving dirty "new" equipment if effing annoying, I agree with that part.

have compressor clean of my s5(about 5 bar), dust, insect and friend went away but stain still there.
seller has to do more effort to make it look like new, if used.

[fullzero]

I got one of these a few years back; as powerful as an air compressor, but way more portable and no waiting for a tank to fill. 

Makes me wonder how much BTC is wasted on compressed air cans.

I like it bigger and meaner... this is my tool of the trade:



And for the home miners, a good ole' electrolux vacuum

if your DHGate store didn't keep refusing my VALID credit card

DHGate isn't Bitmain, its an online marketplace like Amazon or ebay. If your credit card is failing, then your card company is rejecting the transaction.

In regards to cleaning, the debris was caked on, so an alcohol solution was needed and wiped each blade.  Took about 20 minutes or so but they are nice and shiny now.
Didn't mess with the thermal paste.

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

[QuintLeo]

Anything in the 200ish CFM range should work, perhaps down to 150CFM for quieter at the cost of running a little warmer.

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

[shadow1975]

Maybe any link or type of fan. Must be RPM controlable ?

Any link would be useful. Tnx in advance.

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