Edit - he's now posted a video of card running in Novec 7100 Cool
I am using a much bigger box for my final unit and hopefully I can fit 20-25 Neptune cards in the box with a very large radiator.

I will add them 5 at a time until I can't dissipate the heat anymore.

I agree, Avalon first batch has been the only mining gear that has paid off way more than it cost. From here on in your lucky to break even at best. Unless someone comes up with a way to produce 1ph for around $10,000.

Not true... Many of us mined around 50 coin per Jupiter... just so you know....
with all the problems I had with Jupiters, it was worth every red cent imho.

... and Yifu Guo was no angel. There were a lucky few who got Avalons early, but make no mistake,
Avalon is just as guilty(or more) when it comes to orders which were delivered late.

And it cost, what, 60 coins?

... and Yifu Guo was no angel. There were a lucky few who got Avalons early, but make no mistake,

Most of batch-1 that was a big winner. Batch-2 was a toss up. Everything after that was a disaster.

It didnt take Elenelen long to ramp right up to 500mhz with simple vrm heatsinks. Imagine what we could do if that cooling tower, thermal blanket, and that stupid bar were all gone, and replaced with an H2O cooler. the vrms, and any heatsink you put on them would then have excellent exposure to airflow.

That's all fine and dandy. But it's a complete waste of time and money this late in the game. Any tiny bit of performance you might gain is eaten up by miner downtime and the cost of additional parts.

If your Neptunes are running... just let them run.

I can see why jelin was so frustrated with the AX1200i. It won't even power one Neptune module plus controller... the Over Current Protection (OCP) kicks in and the PSU shuts down.

As annoying as this is, it is a safety feature as it would normally be unusual to draw that much current through a single PCIe cable. So i blame KnC for not putting two PCIe jacks on each module, rather than Corsair for their smart PSU. Bitmain put two PCIe jacks on each S3 blade, but it turns out only one is needed. That's a forward thinking design (in case the BM1382 28nm chip needed the power) - KnC take note.

Corsair link software lets you increase the OCP limit which fixes the problem... BUT the link cable is designed to plug into a motherboard USB pin header, not into a USB port (which makes sense as the PSU is designed to be inside a PC). Damn, I've only got a laptop.

I've got 2-to-1 PCIe cables ordered from Cablez, hopefully they will spread the Amps between two ports on the PSU and get around the OCP.

I'm also trying to source an EVGA 1300W superNOVA G2, but no luck yet finding one in New Zealand.

So my Neptune has been delivered, visually looks ok, but I can't power it on yet.

Months ago I kept saying when everyone starts to get their Neptunes they will have trouble powering them up and keeping them cool. This was the first line on my list that stopped my from pre-ordering one. Yea, I was on a "bitcoin high" and "wanted it first" like everyone else, but you have to put some brains into the picture to really figure it all out. The bottom line and my point here is by the time everyone buys all these power supplies and cooling products you will never get even the chance to break even. Just slap on an extra $500+ for power supplies and then if you had any electrical wiring down in your house that's not cheap either. People need to stop complaining about KNC and start using their brains before dumping out $10k on a pre-order. Trust me, I know the feeling. You see a brand new product and want to be one of the first to order it. Your blood pressure increases, you make typing mistakes on the keyboard because you want to move faster, you move some of that bitcoin around and BAM, make that purchase. Then right after the purchase, go to the forum and post a thread that you just ordered blah blah blah blah blah and can't wait to get it. Start posting what order# you got and the torture starts.

If someone can mount an Corsair H80 on the chip and mount a push/pull fan configuration right on the side of the box you can literally bring the size of that box down to a small shoe box size. I've been using that Corsair H80 on my overclocked Intel 3930K processor for a while now and works great. It is a completely sealed system and keeps the processor cool at all times. If there is a will, there would be a way. The ASIC chips are larger in size, so making it work would take a good DIY'er.
