Topic: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH - page 168. (Read 451277 times)

Hi, we are in the same boat. 1 of my s5 blade dead in a month and promised to give shipping label to ship back. But its already 3 weeks since the promised and I never heard back from them again. I send couple email but no reply at all. BITMAIN if you read this please prosess our RMA. I Have been loyal customer since antminer S1.  Thank You

This is off topic but the Novec fluid doesn't get pumped anywhere. This video should explain it better. https://www.youtube.com/watch?v=a6ErbZtpL88

Back on topic. Bitmain, I'm ready to purchase more S5's. With the price of BTC creeping up I think it would be worthwhile.

Not the most complete description but I take it there is an inflow and outflow pipe pair to the tank moving the Novec to an external radiator to exhaust heat and a second inflow and outflow pair to the condenser also to an external radiator?  Ah, found it.  One gallon offered for sale @ $379.95.

I had another S5 loose a blade on Sunday (2nd one that has failed in the 30 days I've had them). I tried using a different power supply and also moving the cables to the other port on the controller but it's still going all xxx's. I'm not overclocking, just running stock settings. I emailed Bitmain support but only got one response asking what kind of power supply I was using. I responded back (EVGA 750G & Corsair HX850) but heard  nothing further from them. Bitmain, can you send me an RMA number and I'll ship this back to Colorado?

This is what i want to do with all my miners https://www.youtube.com/watch?v=a6ErbZtpL88

bobsaq3 and sidehack are spot on at stock/factory clock rates.
We prefer to allow a little more head room for OC'ing the Prisma's and hence have migrated to one DPS-1600BB per Prisma.
OC'ing a Prisma only makes financial sense if the cost per Kwh is low ($0.08/KWh or less).

Then there are the heat dissipation issues that come with filling a room/Data Center with OC'ed Prisma's.
Pursuant to that we are prototyping Open Bath Immersion (OBI) cooling using the 3M Novec Engineered Fluids in custom built polycarbonate immersion tanks.
With the ultimate goal of immersing 32 OC'ed Prisma hash boards, controlled by an RPi w/wireless, in an OBI tank powered by 5 DPS-2000's.
Power consumption should be ~10Kw per tank and dissipate ~32K BTU continuously, enough to heat the average American sized home in a Minnesota winter AND GET PAID TO DO IT.
The residual/excess heat could be used to heat a garage, heat a driveway, heat sidewalks, melt snow off of the roof, heat a pool/hot tub/fish pond, etc. . . . . . .

Our Youtube channel (PlanetCrypto) has some videos of our initial testing.

We no longer power the fan in the S3+ tank as it is not required for condensation.
The heat generated from the S3+ tank supplements the in-floor heat in our little DC.
We have laid PEX in the ground outside the DC as a place to dump excess heat in upcoming expanded systems.

When we get a 32 Prisma board system up and running we'll post some vid's on the channel.

Don't make me have to go buy used lastgen hardware

dogie we need more S5s or the mythical S6. Use your influence to tell them to giterdun!

 

And now the question of the day: Who manufactures the S5 fan and what model?
