A common misconception is that gold is better at moving heat than more common metals like copper. Copper's thermal conductivity is about 23% better than gold. And gold is apparently over 450,000% more expensive, so there's that..
True, forgot about that. Didn't realize pure silver is a little higher than copper, and a diamond heat sink would be more expensive than a gold one :-)

Sort of. Synthetic diamonds are produced in ton per day quantities for industrial applications, but the problem is that they're normally sub-millimeter size. So there is no practical way to combine them into a typical heatsink. It's the same problem with many of the nanomaterials discovered in the last few decades which in theory have amazing thermal conductivities: it's difficult or impossible to make anything sizable and practical for these uses from them.

4x 280x waiting on a 290x so I can add another.
https://i.imgur.com/Fr6Lz0c.jpg?1

What temperaturs do you have there? And what PSU???
coldest one: 67 and hottest one: 75.

Setup:
Proc: Intel Celeron G1620
Mobo: Gigabyte GA-Z68X-UD3H-B3
RAM: Corsair Dominator CMP4GX3M2C1600C7
PSU: Corsair Enthusiast TX850M
        Seasonic M12II 750W 80+ Bronze
GPU: 3x Dual-x 280x 1x Vapor-X and in a few days a Gigabyte 7970

I'll be running the Dual-X's from the 850 Corsair and the Vapor and GB from the 750W, which will also power the Mobo and risers.

I'm planning on building this in a few weeks:
https://i.imgur.com/JzKfKb5.jpg
https://i.imgur.com/6x1Yk9J.jpg
It'll run 7 280x's on 3 PSU's cooled by 6 200mm fans. All arranged vertical to create a natural flow upward.

I plan on something very similar. My drawings allow room at the back so the motherboard can mount inward though. Also I'm only using twin PSU's. It's a 5 card 290 setup (running in a previous frame design), but soon to be a 7 card 290 rig.

I assume you're going for USB PCI-e risers? You might need to make it a bit deeper to allow for cable management.

Keep in touch, look forward to seeing your work! Seems building vertically is in the minority here!

Desktop miner:[u/][b/] 2x Gigabyte Windforece 280X @~1.5mh/s with CGminer 3.7.2 and Win7 x64 Ent, 1x Coolermaster 1kw
Dedicated miner:[u/][b/] 5x Sapphire 290s (Hynix) @~4.8mh/s with SGminer 4.0.0 and Ubuntu 3.12 x64, 1x Enermax Platimax 1500W and 1x EVGA 1300W G2

:-) Granted I'm in the small time with 200gh here, but to be honest I can say I know a thing or two about both cooling and building my own 1 volt 120 amp power supplies.

And 300 volt 400 amp 3 phase power supplies.

That happen to be water cooled. :-)

(giggle)

I wasn't knocking you or anyone else, you have done very good work oc'ing your jalas.  I was just giving you a hard time when you poked that the rest of us were mining with toys since we (most) aren't watercooling our rigs.  Wink

Impossible is a word found only in the dictionary of fools.

*nod* Totally not my intention. I'm amazed at what people are doing on this forum, in a way I'm really knocking rust off my own wings with all this. It's exciting and fun and creative all at the same time.

Good stuff, very good stuff. My apologies if I poked the wrong way.

Version 1.1 of the AntRack, has ~36 ants on it. Still not 100% happy with the airflow and cabling, but its getting closer.

Yes I am  Wink  An Antminer today is worth more than 2 or 3 of the other miners in 3 months...being my point   Cool

My current system runs fine with 1xHD7950 and 2xHD5850 on a Corsair HX850w PSU. I just ordered an extra 2xHD7950, two powered risers and a 850w single rail PSU and I'm starting to be confused on how to wire it up.

What I think I have to do:
- NEVER power one PSU while the other isn't running, so run them simultaneously only.
- For cards powered by a secondary PSU the power from the powered risers must come from the same secondary PSU.

What is the correct way to do it according to you without killing my hardware?

Sorry I'm asking this here but I get mixed answers ranging from "IT'LL BURN YOUR HOUSE DOWN AND KILL YOUR KITTENS" to "nah, it'll run fine".

Look at https://bitcointalk.org/index.php?topic=7216.msg4637321#msg4637321 - 3 same quality PSUs are wired together (every 12V branch) and no problem. 3 of 4 risers are powered with 12V link cut, fourth riser is non powered draining power from mobo. Runs flawlessly for about half a year.

Custom wooden rig, match anyone ? Cheesy

Delivering ~16.6 Mh/s
Burning ~6500W (distributed on 4 circuits of 10 amps each)

Working on a much better 19" rackable rig, cause this beast can't scale no more.
No way I'm going to put a third level on this thing Smiley

I've seen about 100 pages of this thread, but your rig is the beast! It inspired me to save some money and start building! Smiley
