    There are 3 in that rig, interposed between 3090's.
    60, 67, and 71 but they are crappy single fan asus's so the stock cooling solution isn't the best.

    Those 2060's just run hot, it is interesting seeing the differences between identical cards.
    Having a large sample set shows how some cards have been assembled with less care and run hotter than its identical twin.

    The asus ko and ko gaming 3070's are fantastic, but its also the voltages, they run 10w less then the dual oc so obviously i guess with a bit more voltage = more heat.

    Keen to see some more pics of everyone's setup. I'll go first - my downscaled mining on my gaming rig. 3x 3070 + 1x 3080 = 290 MH/s

    I use alot of cable ties. Also Molex connectors technically have a higher current rating than SATA. Also you dont need that SATA to PCIe bridge.

    I like those stands, are they 3D printed, bought or repurposed from something else?

    Custom made entertainment unit , htpc and amplifier both vent through the left cabinet into the left void space also, htpc has 3060 , still have to do the pelmet surround and cornice around to integrate it all properly and the skirting, hopefully i will do a bit this weekend :)

    Top shelf is ETH miner 3 x 3070 , 1 x 1660ti, 2nd setup is 3 x rx480 4gb cards, currently on ETC , storage underneath + sub which i dont think i will run in the cabinet while the miners are in there, speaker towers are fine as is.
    Screenshot_20210604-195954_Gallery.jpg
    Side filler is hinged, can run cabling etc down there, airflow comes from a gap underneath and also from the amplifier/htpc intakes , i put a divider in so air goes into bottom rig motherboard shelf, then up through the shelf cutouts to cool the rx480's, then exhausted into the vent space to go up and through the ETH mining shelf and out the top into the roof

    Vent box in roof cavity , left hand fan is 100cfm 180mm silverstone 3 speed adjustable as direct exhaust , Right hand fan is 144cfm 180mm Silverstone fully dial adjustable.

    Right hand vent connect to adjustable roof vent which i can turn on/off from the loungeroom , when off this side bypasses into the roof cavity also on the Y adapter.

    Havent had to use the heater at all this winter, can fully adjust both the amount of air coming in and the temperature by adjusting the 2 fans speeds up and down to vent mor eor less into the roof cavity.

    3D printed, although I would choose a different design if i was to do it again. Uses too much material and takes too long to print. There are simpler designs now that would work just fine.

    Love this! Great to see all these ingenious ideas.

    Finished building this rig earlier this week.
    upload_2021-6-5_0-22-26.jpeg

    Just need to tidy up some wiring.

    You can get 8pin cpu to 2x pcie cables from Aliexpress, adds extra pcie ports to PSU’s as most have at least 1 spare.

    You are going to need venting with that many GPUs. I used to do this but now I put my rigs inside the cabinet vent the air into the roof space

    yep, working on that now, walling off a section of that room.
    It is in an AC’d room.

    when all the people in the gpu threads complain why they cant buy one. any idea what you've spent in total and total power draw?

    I built it for a mate. My rigs are similar but I only have 2x btc37 boards (1x s, 1x t variant)
    All up cost would be ~ $50k, power draw from hiveOS is 8.3kw

    The rig does 0.1eth/day during slow times, in the recent flux of activity it was doing 0.25/day

    And the Glee bastards trying to downplay the role of GPU mining as to the state of GPU prices:lol:!

    Have you done Absolute Core Clock on Hive OS for your nvidia cards?

    Also, are these rigs on only one circuit or two at your house?

    Yep, all cards are running absolute core, then mem to stable limit.
    All cards are nvidia. 3x 1660s, 31x 2060, 1x 2080ti, 2x 3070, 3x 3080 and 13x 3090

    The rigs are on separate phases, in a workshop that has a 40kw solar system on the roof.
