Hi,

So one of the hashing boards in one of my batch 1 S7 has stopped working, what should I do? Cheesy



If anyone got any tips/tricks I would appreciate it.

It's probably not worth it to send it back to Bitmain for repairs? The shipping cost alone would probably be too much AFAIK. (Norway)

Your board #3 is showing problems too. I'd say try powering just one board at a time. Maybe the problem is your PSU. Maybe that would be the best case Scenario.

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.

Ah. There was that tube where they would build Mineral Oil rigs. They said fans don't burn out even though they can't spin fast at all, because to burn out, there would need to be excessive friction.

Since the motor in fan is just current being run around the fan pole to make it spin, there's no actual strain on the parts. They say however the fans don't actually make any difference in cooling performance, they just looks cool. Until you take them out, then they remain pretty much forever sticky, but however still work normally afterward.

I don't know if those(deltas) fan Specifically would not work under mineral oil, but in that case;

Cheap low performance PMW 120mm case fans definitively do. I dont know if the firmware would accept those readings however? Might be 2x4$ bucks fix, if the firmware just look for a signal.

I need to pick someone's brain about solo mining PEERCOIN with S7's

For whatever reason I just cannot get it going and yes, I'm running a full node with plenty of incoming connections. The router is configured properly. It a matter of getting the miners to talk to the node/wallet. and yes again, I'm running the latest version v0.5.2

If someone is mining PEERCOIN with their S5 or S7, please post your ppcoin.conf file, and what you use for the URL to talk to the wallet.

Thanks

BTW.... My head hurts from beating it on the keyboard....

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
