Great looking rig congrats. Craftsmanship is excellent keep up the good work.
Thanks! I did some work on the waterblocks tonight, should have them finished up completely tomorrow!
Nice setup,did you try reversing the top fans so that they push air on the cards rather than pulling air away? that should solve your heat problem

note : you will need 2500Rpm high performance top fans, not silent 1500rpm
I tried swapping the fans around in several places. Oddly enough, the best I've had it was with 4 top fans pushing down and leaving the fans off of the side completely. I have a box fan behind it all, pushing air down the cards.
I should have picked up some better fans, but even with the crazy high velocity box fan pushing down on these cards I still don't see much better than 80 degrees.
Cool Rig, hope you reach your goal. I just build 2 Rigs with 3*7970 each, mining ltc with scrypt at around 2200 each at their best clocks but right now i have them at 2000 each.
Thanks man, and good luck with litecoins! I have a feeling I'll be mining on those before much longer.
dang thats a really sick rig for right now man! hopefully the asics don't come out for a bit longer and you can hold out and make this thing profitable!
Thanks! I sure do hope so! But I'm probably never going to be able to pay this thing off with coins, not after all the watercooling expense. But, I am still doing better on my predictions than I anticipated. I figured difficulty would be much higher than it is now, hopefully that trend continues!
But, even if I can't pay it off I just swap out the processor and memory I'd have one of the baddest watercooled gaming rigs around. At least that's what I gotta tell myself!
Nice looking rig you got there

Thanks!
stick with 4 7950 per rig you can easy get 2500kh runing under 60c core 80c vrm 1050mhz core 1250 ram 1.050v core ( saphire vaporx 7950 oc dualbios edition ) i have 20 rigs of 4 cards and 1 with 3 cards
Were I to do it again I think I would go for the 7950 instead. This thing is capable of 3gh/s though, I can feel it!
get a 1080 rad there under 120 gbp and are brill
I paid $80 a piece for two koolance 3x140 rads. I don't think I'd be able to get good airflow to a big one like that mounted underneath, and if I mount it up top it covers the pretty pieces!
Also, I'm going to try and vent the hot air outside occasionally. I am going to have fans on the radiators pulling air in, and two fans on the end pushing air out from under the case. I'll have a small section of ducting, then vent straight out a open window.
Kinda like this, except my koolance radiators are about 1/3 as thick as those lol
