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.

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.

See, I don't understand that. If it's an enclosed system and the Novec evaporates off the ASICs dropping their temperature, that energy is in the Novec gas. If it condenses within the enclosed container as it must or it's lost, that energy must be released. The energy wouldn't leave the enclosed container and its temperature would build. He says he might heat a driveway. So, is taking the heat out via whatever fluid is circulating within the condenser enough to remove all the heat?

The fluid vapour is cooled by water.

And the cooled condensate dripping into the lower chamber with the boiling Novec is sufficient to keep the major volume of Novec from rising to a high temperature. I see how the cool condenser would be sufficient without a running fan to condense the Novec. My thought was that an additional cooling of the liquid would be needed.

So, say 4 boards of an S5 cooled in this way would need a minimum of how much Novec I wonder.

Many advantages to Novec. No dust (can seal room), no noise, extreme density, can retrofit ANYWHERE, literally just need a room and water pipes. Works in high ambient conditions, can hook up to very cheap evaporative cooling solutions making it low power.

However, none of these help you and its not designed for small scale.

That stuff is not cheap. The equipment is more expensive to contain it. Good luck

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?

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

I had another one fail a few weeks ago and Bitmain Support was much more responsive then. I don't mind paying the shipping to Denver, just don't want to ship it back without an RMA number or confirmation that they will send me a replacement.

I heard back from BitmainWarranty and just shipped my faulty S5 back to Colorado. Hopefully they can turn it around as fast as last time..
