Probably more rigorous DIY is needed by replacing the whole metal-plate (and fasten the Tower in a different way).

I would probably go back to the old mounting method for the heatsink plus separate VRM heatsinks, I suspect that will provide a better setup since you can get better contact with the individual VRM heatsinks.

Yes that is the idea... and some additional Fan's as well.

if you're serious about mounting the radiator the old way (turn the radiator 90^o, using the long bar/plate) and mounted using the two holes (the one to the right of the 10 pin and the other on the opposite side of the ASIC) - depending on which radiator they used as well, I've got the hardware to do it..
 
  I still have some of the plates, etc. to put it all together (similar to what I put together for the "Super Jup").
  I'm also working on a base/mount that you can put all the boards on (similar to the Jupiter)

  Any design ideas are very welcome!

The frankenJupiter ty-wrap method....
should be fine if your not shipping it....

I'm interested, I saw your work for the "Super Jup" and it was impressive! Are you thinking of something where we remove the Neptunes from their cubes and mount them on your base, plus associated plates and pieces? Or, are you going even further and thinking of a rackmount unit of some kind 

[bitpop]

I doubled up all my pcie connectors by cutting and adding a molex or sata

[proclivity]

i also fell for the hash while you wait "order conversion," but contacted KNC and they have put me back on the 2-for-1 Neptune list.

Now just waiting for shipment.. I'm a batch 0 customer and order still shows paid.

I was thinking along the lines of a base with the boards mounted (5) five abreast, mounted using risers at the corners (10mm - 20mm) to keep the boards higher up to allow airflow underneath.  As well, utilizing the plate and spacers (if an Arctic radiator), to get that brick off the VRMs.

Just a thought ...

In my experience with KNC's 28nm hardware,  the primary thing stopping overclocking/better performance, was heat management.  The best solution was to make sure the underside of the board is cooled as well... even just placing a high speed fan on the bottom of the boards worked wonders.  I suspect that the neptune will be harder to overclock (the female pci-e connector and VRM's seem pushed hard on normal clock speeds, for one),  but having some sort of mounting solution to better cool the top and bottom of the board might be a good place to start. You could do this by having the metal sheet that you mount it raised slightly, and place vents underneath the boards (or cut little asic sized holes) to give room for some high powered fans on the bottom.  An even better idea might be to mount the boards upside down,  and give a place to mount fans on the top of the sheet, with holes in the sheet to allow air to go through.

If one were watercooling these boards,  I suspect that mounting them on their side might work really well also.  That way you could put, say,  a nepton 280L on the top side of the board,  and have a high powered air cooling solution on the other side/both sides to keep the VRM's and that PCI-e port cool.

Just some thoughts...

Case1:
I don't think so. It's only an needless try to get out more of this machines. But it will not be possible, because you can't
get more out of an old horse.

It`s only wasted time and electricity.

Case 2:
They make it for fun

Case 3:
narrowness


Most cases 1 and 3 together

lol guys!

I'm only frustraded about the frankenjups

p.s. I worte today to the chamber of commerce and now waiting for an answer

[mo_mo]

anyone in eastern canada host miners?

[jtan1ph]

Hash while you wait started mining. How do I reverse this?

Hash while you wait started mining. How do I reverse this?

May be difficult now since it has been started. Best chance is to contact them by phone asap, and cry a little bit. If it doesn't work, try yelling.

Check it out - someone posted a video of them powering up 4 neptune boxes

Let's hope that was KnCMiner's data centre.

Maximum operating temperature of the BMR46x series is 125 C.

Elenelen, when you get a chance could you please read the numbers on the two black 8 pin packages near the side of the board and post them here ?

There is no way to read anything on those VRM-boards: completely covered with the aluminum plate.

Not the VRM boards, the two 8 pin packages near the edge of the board please. They are in plain sight in the recent photo posted here ( https://bitcointalk.org/index.php?topic=170332.msg7436143#msg7436143 )

Elenelen, have you had a chance to check these 8 pin packages yet? I'm curious to know too.

Yes, but no sorry: I cannot read anything (all is covered by the plate or foam).  Next weekend I will disassemble one box... I will post then.

[smoothrunnings]

I have it running now (I guess I'm the first...)

It does: about 3.3 Th  and 1950W at the wall (the internal ASIC-monitor gives about 1440W...I have no idea where the difference is going to).
The chip is running on 475 Mhz (and can be set to 500 {not tried yet}).

There is one new thing on the controller-board: on plug-6 there is a small display-board which gives info about the IP-address and Hash-speed (very nice)... but this means as well that 5 boxes is the maximum.

The one PCE-power plug isn't running hot {the fan is indeed pressing air through the hole}, but the cables are 44 degrees Celsius.

Post some pictures...

[shmadz]

must have got my tracking number sometime last night as well.

It appears they are actually shipping en masse.

did anyone notice if the hashrate spiked then dropped recently? <smirk>

or if their was a picture of the bottom of the board...you could plan out one big heatsink for the bottom that would raise it up and then you could just put a high powered fan in front and would cool both top n bottom at same time...or just put copper vrm heatsinks on top n bottom like i did n use raisiers like i did...but i fear with the already high heat...you need above n beyond just the small heatsinks...unless maybe if you use server grade fans lol

could also just solder another female pcie connector on the bottom couldn't ya? idk anything bout that thou

kinda curious if that first nep. guy how his vrms are holding out? seeing any black smd caps yet?

[tolip_wen]

I took the bait (while you wait) and spit it out.
My 15Kilogram box is in Germany now (headed to Chicago area).

THANK YOU FOR THE HEADS UP IN THIS THREAD!!!!!!

Had I not spit it out I would have traded 1 neptune for under 24 hours of hash while you wait.
It shipped same day as my HWYW would have started.

They make it easy to dislike/distrust them.

Perhaps I neet to get fitted for a hater hat.

On another note!!!
FrozenCPU now takes bitcoin!
They sell water cooling equip.

It's too bad RAM waterblocks are so expensive, 10-15 of them would tame a neptune's VRMs.
(I'll try making my own out of copper tubing)

I waited till shipping notice before installing new electrical load center.
Around USD $150 in parts if you DIY!    


YMMV
