      tbh you’re gonna struggle with those cards plugged directly in to the mobo. The air gets diffused all over the place rather than neatly out of the backplate (connector end) which is fine for a single GPU but useless for multicard setups. Raising the card so i can suck in cool air rather than the hot air from the back of the card in front (clue: shut down the rig and feel how hot the back of the card is) will help hugely. I tried the 120mm fan trick but ended up with a bunch of 12" desk fans.

      Go to page 4 of this thread for some pics… Pyxis uses 4x 7950’s and i use 4x 7970’s and we both came up with the same(ish) designs although Pyxis looks more refined ;).

          Jeese Nut, just seen your rigs, what is the total combined wattage of all that? Gotta be touching 6000/7000W+ what are you plugged into? The Cooker or Shower ring main? :D

            Just shy of 7000w including the fans and the AC unit which runs on fan only mode most of the time (anothe 1.5kw when it gets too hot).

            All running from the neighbours shed! :-X

                  Joking aside i have a separate 40A breaker at the house attached to ~50m of 10mm SWA that runs down to my cabin where there’s another CU that has 2 circuits for the miners (3 on 1, 2 on the other). I did try them all on 1 circuit for shits and giggles but the 2.5mm T&E got rather hot! :-[

                    Yeah man it would get warm, it’s only good for circa 22Amps you are pulling around 30Amps :D
                    I wired my shed up to a 30Amp breaker on the MB, I have my own little hobby workshop in there, complete with compressor, welder, spray booth, temp controlled curing cabinet (except my miner is currently set up in that :) )

                              Which 7850s are you using here? What options are your passing?

                              I can’t get over 530 on mine.

                                I am running Gigabyte and MSI 7850’s and that is both cards combined I posted. MSI is getting 300 k/h each and the Gigabytes I’m getting 343 k/h each when it is full speed, but I am waiting for a replacement on one of the Gigabytes… No overclocking and zero h/w errors…

                                            wow… guys running rigs at 80c+?..

                                            I got:

                                            2x 7870 420kh each at 75c
                                            2x 7790 300kh each at 70c

                                            I was quite impressed with the 7790 (didnt look at stats before i bought)… for those that want to best bang for the buck… $150 card doing 300kh and is extremely power efficient.
                                            [/quote]

                                            ok so what is your setting???..I cant get more than 244kH/s from 7790 so far.
