Hello to everybody,
My question si: can I do the same thing with gridseed? So I can remoove the fan and put these GridSeed unit into the mineral oil.
Tnx
No. However, the gridseed not need fan for litecoin mining. It is suitable for passive cooling. Heh?  Why not? What's so special about GS that would prevent it from being cooled via mineral oil? |

Ignore my post (answer if you want others to see) but I've sent you an email.
Hi Sportswood,
Would this case be suitable for use as a standard pc open air case?
I want to use this case for a gaming rig with the hope of being able to mount the water cooling like you've mounted the fans.
My main goal would to be to attach a bracket that will take a lcd monitor on the base of it and stand it up long ways.
Do you think this case would suit this setup? Or is there another case you make or additional brackets you can add to it that might be better?
Ok. It would be easier to build a custom case, using the same building materials. For example, here's a SFF:    |

What are the dimensions of the heatsinks?
What specific bit, they're quite contoured and are definitely custom. I'd have to take on apart again. I just need the outer dimensions in order to properly size a case for them, ala:  The heatsinks will rest on the bottom "lip" of the support beams, so I just need to know how much room is required between the beams. |

Bitcoin / Hardware / Quiet server cabinets

Now that the mining hardware has matured to where all of them ship in there own case, I thought it would be a good idea to offer server rack frames for mining equipment and quiet server/mining cabinets. Made from slotted aluminum extrusion, this unique material offers the possibility to build 3-4 layer side panels and to be very modular e.g. easily increase depth/height of the rack by simply adding "modules." Here is a model of a 8U frame (these could be built at any U height):   With an SP10:  All comments/suggestions are appreciated! Thanks! Rich |

I should have some cool renders for you soon of the new backplate / heatsink assembly that will ship with the boards.
When dissipating the kind of heat that one of these chips can put out getting a lot of pressure on the cooler is very important. Unfortunately it's very hard to get those kind of pressures without warping the board using the stock backplates that ship with a heat sink or closed loop water cooler since they just don't support directly under the ASIC. Even using a piece of flat metal is difficult, as there are ~300 capacitors under the chip to ensure smooth voltage to the dies.
Our solution for the production boards was to shuffle those capacitors around, leaving a cross of flat PCB in the center of the chip. We then milled four pockets in the back plate under each die where the capacitors are, but left the meat of the backplate in that cross that runs through the center of the ASIC, so it bears right against the PCB. Voila, you can tighten down the cooler an insane amount, with no appreciable board flex.
In addition, rather than just make a backplate out of flat metal, we extended the area and made it out of aluminum heatsink. Not only do the fins add some extra rigidity, but the backplate/heatsink combination extends out to cover a big area of the ground and core voltage planes, helping to cool off the power supply components. The backplate is wide enough that it can mounted to the board with four #6-32 screws and a 105mm square hole spacing, which means if you're using a 120mm radiator like the H80i you can mount the radiator on standoffs to the backside of the board, or just install a 120mm fan blowing down on the heatsink to really keep the DC/DC stage cool.
The heatsink is also symmetrical, so if you use a case and your airflow is side to side instead of front to back, you can just rotate it 90 degrees to make sure you get the optimal flow over the heatsink.
Looking forward to the renders.  |

Guess who designed and built that case in the picture? Yep. Any similarity between my "wide" mining tray and your rack size design is co-incidental. Mine is a natural evolution of my "wide" tray, but deepened/narrowed to work well with cheap server PSUs.  |
