i'm working on oil immersion cooling, remove the fans n stickers then dip the whole s7 into oil bath. use a car radiator for cooling the oil, pumps to circulate the oil in tank.

have to "cheat" the fans. s7 needs to "see/detect" 2 fans or else it won't mine. not difficult to "cheat" it.

coming soon heh . . .  

Why not just leave the fan on and spinning? They'd move the oil through the s7, but spin much slower. Since the motor would be perpetually oiled, i dont think it would damage them?

They are meant for 4000+RPM operation in open air.  Oil is too viscous, they would burn out trying to move that much liquid and probably melt some stuff.

Is there still not any 3rd party cooling kits for the S7? I'm considering selling my last S7 thats in Canada, but only because of the noise.

I wonder if it possible to use the Antminer S3 water block and a cooling kit from syscooling.com ?
If they still sell that stuff.

There was this mod with S5: https://bitcointalksearch.org/topic/modify-s5-antminer-to-watercooling-929437

They have been out of the game a long time, and in my opinion for good reason.  Last thing I would do with a nice S7 is mix syscooling gear in it.   

I would go for a fan mod and run at lower freq.  Or other ways to make noise less.  There have been a few mods some have shown. But I would stick with air cooling personally.

Dunno, i would not mind a completely silent S7. I dont know if syscooling would be the go to or not, however.

Got to love the wonderful support we're getting from Bitmain.  Almost 2 months and no response to my question.

Maybe something like this using a bigger and quieter fan!

Yeah, maybe a duct and a 360mm fan ? Cheesy

Just out of interest I have a 2 month old S7 B8 that has lost a hashing board,

I have emailed a previous contact at that I had regarding another S7 that had essentially bricked its self. She was called "Sherry" at "[email protected]"
However I haven't had a response?

I am concerned as its getting close to the end of its warranty :/ and I am left with a 2 hash board S7  Angry

Is there any other emails people recommend?

Regards

'The right to privacy matters'
Batch 13, unlucky for some? is up. Small reduction in price to $637, ships out from March 21st.

Rich




I see a batch 13 at under 600 usd for sure. And I do not see an s-7+.

I do not know if they will do a batch 14.



Well I got the batch 13 correct as for the price I was off.


637 is pretty good price.



Hello, evreryone

I was one of the ''lucky'' batch 1 owners.
failed from the start, random offline issues and afer a coupple of weeks only one board out of tree worked!
I sent back for RMA, 2 faling boards and controller board.
thing is i got back 3 boards no controller, will the S5 controller work in anyway with it causes cables are the same....
any help appreciated 2000 euro went to 700 $ in the waiting peride.

sorry bitmain your trusted and valued in my opinion but this sucks big time................!

Wow I thought I got fucked on my batch 1!

Hey tell you what I am renting some hash right now. I will point it at ck solo pool.

If it hits we can split the block


here is the rental it will go for 20 more hours

this was done before and they even said the last s-5's they sold were used.
Every single miner bitmain sells is "used".  I think they roi most (maybe all) of their gear in house before they sell them.
Bitmain runs their equipment like crazy, I wouldn't be surprised if one or two arrive DOA. Notice how each batch gets cheaper? That's because every batch is based off how much money they make from them (at least that's my theory). S7 B12 looks too good to be true, i'll hold off on them. No ROI expected anyways, so its basically another used s5 from ebay. No profit, and the only difference is that bitmain probably ran it a lot harder than a regular person would.

Batch 8 was really last big change.  They have kept same S7 design since then, where they made less chips and more frequency.  This change for sure made it more profitable as less chips.

The batches now are sold at lower prices due to difficulty, they seem to follow it.   We really don't read a ton of DOA considering amount sold.... so that is the good thing.    But it is true when you make a miner in batches you don't sit it in a box new waiting for it to ship out, it goes onto a rack and mines unless sold soon after made.   This goes for any company though on making miners no one let's them sit in boxes for long periods of time.
