What is the price of a H60?
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.
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.
Do you know how much heat the H80 can remove? I think those ASICs are about three times the power draw of your 3930k... it probably wont be enough.
theres the H-100 as well, but were only talking about a single asic here... about 150-200 watts max per asic (300 watts total draw for the entire cube according to KNC) found here: https://www.kncminer.com/news/news-96 The asic alone may be half that maximum(an estimation)
It can be done with H60's. How many watts of you think that cooling tower is capable of? It's already pushing it's spec limit in warmer climates.
Surely even an H60 will be far superior to that bulky archaic arctic tower heatsink.
thanks for donation btc for my english!!!!

There was actually "Talk" early on about a dc/dc "Team" who was supposedly working on a custom solution if I remember correctly.... evidently that never transpired.
Nobody volunteered a Neptune box as a guinea pig and the crowd funding never got off the ground.
I might play around with one of my 4 VRM Saturn modules and see if I can upgrade the VRMs on it. The problem is, they are GE Critical Power modules so any results wont be conclusive for Neptune owners.

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.
So true. Been there, done that, stopped doing it. If the Math doesn't work out then don't do it.
soon i will review their cloud mining service on my blog

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.

Actually it currently takes 10 days with 3.3 TH/s to mine a bitcoin.
Can you imagine what its going to be like for the August/Sept SP30 customers ? Thats a few more diff changes down the road still ...
pretty much screwed like all the rest of the preorders to date...only one that worked great was avalon preorder...everyone thinking they will get that kind of success
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.
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.

Whatever gave you the idea Avalon was so "Golden"? and after a good shafting from Avalon, I bought from BFL.
Jupiter made up for all that, and more.
...but I agree.... Neptune, and every other miner screwed from here on out.... sad
There was alot of evidence of Avalon secretly mining weeks/months before delivery.

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.
Wat? You're selling English lessons for BTC? lol
no i need btc donation
for my english lesson
see my btc adress and donation some btc
untill now only 1 donation for my lessons
please donation some btc
maybe ask knc to daontion some btc

Wait, what?!
You've been mining BTC for a long time and you had $10k to buy a Neptune. But you can't afford to pay for your own English lessons?
Not true... Many of us mined around 50 coin per Jupiter... just so you know....
And it cost, what, 60 coins?

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