Willing to buy;

Working S3 Controller + 2x Working S3 Blades including all connection cables. Basically a S3 without the heatsinks + husk/frame. = 0.2BTC Shipped per working set
(Willing to buy the whole thing if it does not make a big difference on shipping, in the case where you would rather not disassemble)

Working S5 Blade + Support bracket (black metal thing you bolt controller and heatsink into) = 0.4BTC Shipped

May also be interested in picking up dead S5 blade in acceptable condition. 10$/per.

Also interested in picking up 18 but also 16 pins long cables for S5's.

Question: one miner=three connectors? Could you connect a total of three S7 to one controller? Or only two?
I also see that Phil used one short connector from the second S7, so only 2 long ones needed, right?
Therefore to hookup three machines you need four, not six long ones-am I right or not?
Thanks.

Still nothing useful as to proving a board was "burnt with flame and smoke". If you're saying its due to the smell then its probably from someone unglueing heatsinks off a dead board with a torch. If you're saying that the dark ones are a different color because they've been in a fire, that's even more ridiculous - its nickel plating.

bitmain it says on the website that the weight is 4.5 kg  S7 someone who can please check if the weight is correct?

Did you know that the weight of S5 already packed weighs 3.2 KG? bitmain and declares that the weight is 4.2 kg? let's see who still has the courage to say that bitmain is honest?
you know that means 1 KG more in shipping it?

They were moving support to https://bitmain.zendesk.com/hc/en-us with tickets.  Not sure how far they made it on it.  I kinda feel they get so many emails they never fully made the trasition.  I would agree if they had a more concrete help desk type system it would be much better.

I am not a fan of their recent moves on compensation.   But we gave them the trust to do it.  There was no solid TOS or anything that protected us.  We kinda went in blind and suspected if anything was truly late they would fix it..... so it gave them full power on it.  They choose a pretty crappy compensation no doubt.  But there is not much we can do.  

I mean it's already midday Monday in China.  If bitmain wanted to come out and say "Were sorry heres some coupons" or anything they could have.    I hate it but I feel no amount of these threads or posts will change their mind.  

It will take someone to mod most likely.  I just don't see another C series for the many reasons I have posted earlier.

You can look at their partner syscooling on C1, and S5 mod.  They have not logged in for months.   So that does not sound very promising.

S5+ board do fit on S5 waterblock ? Right ?

I appreciate your offer, but a bit too high for my pockets.
I purchased a S5 for 1.35BTC shipped a month ago.
For 3 BTC I can get 2 units with 4 heatsink, 2 controller, 2 case and 2 fans. shipped and still have some change

VAT do kill prices on international trade  

Question :

I want to replace the DAMN noisy fan.
I expected a big drop in noise but at 3200RPM, it is still annoying.
I could trick the temp sensor to lower fan speed but I don't want to go that route.
I run at 46 Degrees C., fan speed could be much lower.
How can I set my RPM fan to run lower in controller ?
I can build a external temp control circuit but I feel lazy and want easy solution.

Suggestions ?

Someone mentioned they void your warrantly on the S7 if you don't plug cables into all 3 jacks, which is funny because it's a 1200W machine that "requires" 10 cables to run but their 1600W PSU on gives you 8 (and that 18AWG). Double standard much?

About a year, year and a half ago Bitmain was taking enough flak from everyone that they actively worked on improving customer service and warranty fulfillment. It looks a lot like they either stopped caring or decided it wasn't a worthy investment.

Since this thread is already here, I might as well use it. Today I resurrected a dead S5 board but it's the early version with 16-pin cable so I had to borrow a controller to test it. All the controllers I have running around use the 18-pin. I have the 18-pin signal pinout already figured out but I haven't done anything with a 16-pin before today. Anyone know offhand what difference there is between the two?

Do you have a less primitive mean to try to repair it than an oven? It was the only suggestion made to revive a board that i have no real use of unless it can work. If i can't revive i'll probably ship it to sidehack and thats that.

Doing this does not seem like it could damage the chips, so anything goes.

I'm very interested in any other suggestion pertaining to this.

Yes. Yes. The holes don't look self drilled, they all have the factory groove in it. I didn't pay for this blade, i only paid for the rest of the miner, so i don't see how i have been scammed.

Okay so heres a picture of the board, this thing has way too many screws;

1)Should this side be up or down? I wouldn't want stuff falling off if it become lose when the solder is melted! xD

2)Also this is kind of smudgey, could this cause any issues?;

And for the record, here is a picture of the previous pasting job;

Time to start cleaning.

You do not recommend using S5+ blades with S5 controller with S5 software or S5+ software? One second you say S5 software is bad and the next you say S5+ software is bad.

Are they both bad?

The post you sent me, he says they run at 2.2th. If they ran at 2.7TH it would possibly be worth it. Since i used 2.2TH for the math. While i did 2.6TH for 2*S5 for 2.2BTC~ That is the price i been picking up parts at, around 1BTC for a whole s5. Or 250$~

And i am in Québec, but the tax isin't applicable if the seller pick value = 1$ for electronic parts. Regardless the seller does not wish to ship outside the US. So i need to find something else.
