Yes waterheater i mean. So you do have 220v So why is all this discusion about then? Just change the outlet to 220v.

And the cooling. I think the two jetengines will solve that but still have to work it out.

This is what i did with my S5 but don't think it's going to work for the S7...

Hi guys,

I see you got some big problems with your power outlet in the usa. But how does that work for you? I'm in Amsterdam and ofcourse we have 230v and 16A outlet. So i can use 3600 watt on one outlet. But i see you guys can only run one S7 on one outlet?? So my question is how many outlets a house have there? And don't you have some household stuff that takes like 2000 watt? (watercooker ore so)

And one more thing..... The sound the S7 is going to make. We all know it is going to be loud.......very loud. But you can just build a box around it and problem solved. Right?

Hi There,

Trying to get my U3 running. But it does not see it.
I made the .bat file but that's not working.
Using windows 7 64.
Would make my day if somebody could help. I'm going to kill it soon......

Thanks Beffje

Had the same last week.
I'm running 5 S5's so i was pretty sick from it.
2 where broken. One had a board with 4 chips that don't work any more.
And the other one had a hole board that's broken. This one is a month old so it's going back to bitmain tomorrow.

Then i did a furmware update and i think bitmain fixed it olready. Becouse on friday my internet went out again and temp stayed the same for the 5 minits i checked. Anyone tried to do this?

What temp data you need? So i don't have the standard data. But i think it's about the same temp. Just not that noisy. I can tell you that the bottum sink is getting warm. So in my eyes it is doing his job. And it's like 10 min. of work. Drill out the outer holes off the blok. Stick some legges in. (M4) And the S5 will fit execly!

Who sayed any thing about more air flow?
There is less air folw that the standard fan. So that story about you sensor is bla.

So what to do when you have less air flow and you want more cooling.....
Increase the cooling surface 

As we know the heatsick of the S5 is flat on the gound. So i put some cooling past in between. Bottem sick is getting hot so it is doing his job.

And noise level. (heatsick vers.) 60 dB
The wrapped one. Was just a little les then normal. But still way to much...

Hi guys,

Nice feed back. First it is a 140 mm fan. So it olso does the bottum sink.

Then i tested a closed one.

But that was not much better.

I olso did a hanging one and that runs hotter. And if this would be better Bitmain would make a different setup.


Then the differents in temp.......
I think it runs the same as the standard. Mabye a little cooler even. As the room temp can go up to 35 c and the miners are still running at 65 c at 400M

I'm in Amsterdam.
But the fams are fine thanks

Hi there,

Thanx for the help. So i need to store the image online first?

I just want to share my custom cooling. It's easy and works just fine.
You need an old S1 for heatsink and a Noctua NF-A14 industrialPPC-3000 PWM, 140mm and a other 120mm fan.

So first you need to fix some legs. Like this.


Then put some cooling past on the bottum of your antminer. The heatsink part. And them place it on top of the sink with the laggs



Drill a hole just above antminersticker and use a stockfan bolt to place new fen.



On the other side i have a noiseblocker B12-P

I was not planning on posting this that's why it's a bit crappy. But maybe it can be to some use.





Running 5 at 60 dB.
